The scenario describes a patient presenting with symptoms indicative of an acute myocardial infarction (AMI) and subsequent development of cardiogenic shock. The initial diagnosis of AMI is coded using the appropriate ICD-10-CM code for ST elevation myocardial infarction (STEMI) of the anterior wall. Following the STEMI, the patient develops cardiogenic shock, which is a complication directly resulting from the myocardial infarction. ICD-10-CM guidelines, specifically Section I.C.9.a.1, state that when a patient develops a complication that is a direct result of a condition, the complication should be sequenced as a secondary diagnosis. In this case, cardiogenic shock is a direct sequela of the AMI. Therefore, the AMI code should be listed first, followed by the code for cardiogenic shock. The specific ICD-10-CM code for STEMI of the anterior wall is I21.09 (ST elevation (STEMI) myocardial infarction involving other coronary artery of anterior wall). The code for cardiogenic shock, not elsewhere classified, is I25.5. The correct sequencing reflects the causal relationship, with the AMI as the principal diagnosis and cardiogenic shock as a complication. The question tests the understanding of principal versus secondary diagnoses and the application of ICD-10-CM coding conventions for complications.

The core of this question lies in understanding the hierarchical structure of ICD-10-CM coding and the principle of assigning the principal diagnosis. The scenario describes a patient admitted for management of a diabetic foot ulcer that became infected, leading to sepsis. The diabetic foot ulcer is a manifestation of the underlying diabetes. The sepsis, however, is a distinct condition that developed during the admission and is the primary reason for the patient’s current state of illness and treatment focus. According to ICD-10-CM Official Guidelines for Coding and Reporting, Section I.B.4, “The principal diagnosis is that condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital.” In this case, while diabetes is the underlying chronic condition, the acute, life-threatening sepsis is the condition that necessitated the admission and the extensive treatment provided. The diabetic foot ulcer is a complication of the diabetes, and the infection leading to sepsis is a further complication. However, the sepsis itself is the most severe and immediate threat to the patient’s life that the hospital team is addressing. Therefore, the coding should reflect the sepsis as the principal diagnosis. The underlying diabetes with its manifestation (the foot ulcer) would be coded as secondary diagnoses. The specific ICD-10-CM codes would be selected based on the documentation for the type of diabetes, the specific site and severity of the ulcer, and the type of sepsis. For instance, a code from category E11 (Type 2 diabetes mellitus) would be used, followed by a code for the diabetic foot ulcer (e.g., L97.5- for foot ulcer without gangrene, or L97.4- for foot ulcer with gangrene, with the fifth character specifying the site). The sepsis would be coded using codes from category A41 (Sepsis due to other and unspecified microorganisms), with the appropriate fourth character for the specific organism if known, or A41.9 for unspecified sepsis. The sequencing prioritizes the condition that required the most significant medical intervention and was the primary reason for the hospital stay.

The scenario describes a situation where a patient presents with symptoms of a urinary tract infection (UTI) and also has a history of chronic kidney disease (CKD). The physician documents both the acute UTI and the pre-existing CKD. When coding for this encounter, the primary diagnosis should reflect the condition that occasioned the admission or the reason for the encounter. In this case, the acute UTI is the immediate cause for the patient seeking medical attention and receiving treatment. However, the presence of CKD is a significant co-morbidity that affects the patient’s overall health status and management. According to ICD-10-CM Official Guidelines for Coding and Reporting, when a patient has a condition that is not the principal diagnosis but affects the treatment or management of the principal diagnosis, or is a significant co-morbidity, it should be coded. Specifically, if the CKD influences the management of the UTI (e.g., requiring specific antibiotic choices or dosage adjustments due to impaired renal function), it should be sequenced after the principal diagnosis. The ICD-10-CM code for acute pyelonephritis, a specific type of UTI, is N10. The ICD-10-CM code for chronic kidney disease, stage 3, is N18.3. Therefore, the correct coding sequence would be N10 followed by N18.3, reflecting the principal diagnosis of the acute infection and the significant co-morbidity of CKD. This sequencing accurately captures the patient’s clinical picture and supports appropriate reimbursement and quality reporting at Certified Coding Associate (CCA) University, where understanding the hierarchy and impact of co-morbidities is paramount for accurate data abstraction.

The scenario presented involves a patient undergoing a complex surgical procedure with multiple distinct components. The primary diagnosis is a malignant neoplasm of the ascending colon. The surgical procedure involves a hemicolectomy of the ascending colon, a primary anastomosis, and the creation of a temporary diverting ileostomy. The documentation also notes the presence of adhesions from a previous abdominal surgery, which required lysis during the current procedure. To accurately code this encounter for Certified Coding Associate (CCA) University’s rigorous curriculum, one must apply the principles of ICD-10-CM and CPT coding. For ICD-10-CM, the principal diagnosis is the condition chiefly responsible for the admission. In this case, it is the malignant neoplasm of the ascending colon. The specific ICD-10-CM code for malignant neoplasm of the ascending colon is C18.2. For CPT coding, each distinct procedure or service performed must be identified. The hemicolectomy of the ascending colon with primary anastomosis is a single, integrated procedure. The creation of a temporary diverting ileostomy is a separate procedure. The lysis of adhesions is also a distinct service performed. According to CPT guidelines, when a procedure is performed with a separate ostomy, the ostomy is coded separately. Furthermore, lysis of adhesions is coded when it is performed in conjunction with another procedure. Therefore, the coding would involve: 1. The primary procedure: Hemicolectomy, ascending colon, with primary anastomosis. This is represented by CPT code 44140. 2. The secondary procedure: Creation of temporary diverting ileostomy. This is represented by CPT code 44310. 3. The additional service: Lysis of adhesions. This is represented by CPT code 44950. When multiple procedures are performed during the same operative session, modifiers may be necessary to indicate the relationship between the procedures and to ensure appropriate reimbursement. In this scenario, the hemicolectomy is the primary procedure. The ileostomy and lysis of adhesions are secondary procedures. While not explicitly stated in the question that a modifier is required for the secondary procedures in this specific context, understanding the application of modifiers is crucial for advanced coding. However, for the purpose of selecting the correct set of codes representing the services rendered, the combination of 44140, 44310, and 44950 accurately reflects the documented procedures. The question asks for the correct *set* of codes, implying the identification of all distinct services. The correct approach involves identifying the most specific code for each service performed. The correct set of codes is 44140, 44310, and 44950.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection (UTI) and a concurrent diagnosis of hypertension. The physician’s documentation notes the presence of bacteriuria without a documented urinary tract infection. In ICD-10-CM coding, it is crucial to code to the highest specificity documented. The presence of bacteriuria, as noted, is a specific finding. However, without a confirmed diagnosis of a UTI, coding for a UTI would be inappropriate. The ICD-10-CM coding guidelines emphasize that symptoms, signs, and ill-defined conditions are not to be coded if a definitive diagnosis has been established. In this case, bacteriuria is a sign, and the absence of a confirmed UTI means the definitive diagnosis is not present. Therefore, the coder must select a code that accurately reflects the documented findings. The code for “Bacteriuria, unspecified” (e.g., R82.40) is the most appropriate choice as it directly reflects the documented presence of bacteria in the urine without a confirmed infection. Hypertension, being a co-existing condition, would also be coded (e.g., I10, Essential (primary) hypertension), but the question specifically asks about the coding of the urinary findings. The explanation focuses on the principle of coding documented findings versus presumptive diagnoses, a core concept in accurate ICD-10-CM application at Certified Coding Associate (CCA) University, ensuring that coding reflects the physician’s documented clinical judgment and adheres to coding guidelines to maintain data integrity and proper reimbursement.

The scenario describes a patient admitted for an exacerbation of chronic obstructive pulmonary disease (COPD) and also presents with a newly diagnosed urinary tract infection (UTI). The physician’s documentation clearly indicates that the COPD exacerbation is the primary reason for admission, as evidenced by the patient’s respiratory distress and the treatment focus on managing their breathing. The UTI, while present and treated, is documented as a secondary condition that did not necessitate the admission itself. According to ICD-10-CM Official Guidelines for Coding and Reporting, the principal diagnosis is defined as “the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care.” In this case, the COPD exacerbation fits this definition. The UTI, being a co-existing condition that required treatment but was not the primary driver of admission, would be coded as a secondary diagnosis. Therefore, the correct coding sequence would prioritize the COPD exacerbation as the principal diagnosis.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection (UTI) and a concurrent diagnosis of hypertension. The physician’s documentation notes the presence of dysuria, frequency, and suprapubic pain, consistent with a UTI. Additionally, the patient’s history includes essential hypertension, which is being managed. The coding guidelines for ICD-10-CM require that when a patient has a condition that is being treated or managed, and another condition that is also being treated or managed, both should be coded. In this case, the UTI is the primary reason for the encounter, and the hypertension is a co-existing condition that requires ongoing management. Therefore, the appropriate ICD-10-CM codes would reflect both the UTI and the essential hypertension. The specific code for a UTI, without further specification of organism or site, is typically found within the N39.0 category. Essential hypertension is coded under I10. The question tests the understanding of how to code multiple diagnoses present in a patient encounter, emphasizing the importance of capturing all conditions that affect patient care and management, a core principle in accurate medical coding at Certified Coding Associate (CCA) University. This aligns with the university’s focus on comprehensive and accurate data capture for both clinical and reimbursement purposes.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection, specifically cystitis, which is an inflammation of the bladder. The physician’s documentation notes “dysuria” (painful urination), “frequency” (frequent urination), and “hematuria” (blood in the urine). The ICD-10-CM coding guidelines direct coders to assign codes based on the physician’s documentation. For a confirmed diagnosis of cystitis, the primary code would be N30.00 (Cystitis without hematuria). However, the documentation explicitly states “hematuria.” According to ICD-10-CM, when hematuria is present, it is coded separately if it is a significant finding or if it is the primary reason for the encounter. In this case, the physician has documented it alongside the symptoms of cystitis. The guideline for coding symptoms when a definitive diagnosis is established is to code the diagnosis. However, hematuria is a specific finding that can be coded. The most appropriate code for hematuria is R32 (Urinary incontinence, unspecified) if it were the sole symptom without a definitive diagnosis. However, for the presence of blood in the urine, the correct code is R31.9 (Hematuria, unspecified). Given the documentation of cystitis with hematuria, the coder must select the most specific and accurate codes. The physician’s documentation supports both cystitis and hematuria. Therefore, the correct coding approach involves assigning a code for cystitis and a code for hematuria. The ICD-10-CM index would lead to N30.00 for cystitis. For hematuria, the index would point to R31.9. The combination of these two codes accurately reflects the documented clinical picture. The presence of hematuria, even with a diagnosis of cystitis, warrants a separate code to fully capture the patient’s condition as documented by the physician. Therefore, the correct coding would be N30.00 and R31.9.

The scenario describes a patient presenting with symptoms indicative of a complex condition requiring a specific diagnostic approach. The physician’s documentation notes a persistent cough, fever, and abnormal findings on a chest X-ray, leading to a diagnosis of pneumonia. The subsequent treatment involves a course of antibiotics. In ICD-10-CM coding, the primary diagnosis is the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital. Here, pneumonia is clearly identified as the reason for the patient’s encounter and subsequent treatment. The documentation supports this diagnosis. Therefore, the principal diagnosis code should reflect pneumonia. The specific ICD-10-CM code for pneumonia, when not further specified by organism, is J18.9 (Pneumonia, unspecified organism). This code accurately captures the documented condition. The explanation of why this is the correct approach involves understanding the hierarchy of coding, where the principal diagnosis takes precedence. It is crucial for accurate reimbursement, statistical tracking of diseases, and quality of care assessment, all core tenets of the Certified Coding Associate (CCA) University’s curriculum. Misrepresenting the principal diagnosis can lead to claim denials, incorrect public health data, and a failure to meet compliance standards, which are heavily emphasized in the university’s program. The selection of J18.9 is based on the direct documentation of pneumonia as the primary reason for the encounter, without further specification of the causative agent.

The core of this question lies in understanding the interplay between clinical documentation, coding guidelines, and the principles of accurate reimbursement within the context of Certified Coding Associate (CCA) University’s curriculum. Specifically, it tests the ability to identify when a diagnosis, though present in the medical record, is not coded as the principal diagnosis due to its relationship with another condition or procedure. Consider a scenario where a patient is admitted for a planned surgical repair of a hernia. During the postoperative period, the patient develops a severe urinary tract infection (UTI) requiring antibiotic treatment. The physician’s documentation clearly states the UTI as a complication of the postoperative care. According to ICD-10-CM Official Guidelines for Coding and Reporting, when a patient is admitted for a procedure and a condition arises during the postoperative period that is not related to the original procedure, the condition that prompted the admission is coded as the principal diagnosis. However, if the condition arises *during* the postoperative period and is *related* to the original procedure or its management, the principal diagnosis should reflect the condition for which care is being managed. In this case, the UTI is a complication that requires management and influences the patient’s care during the admission. Therefore, the UTI would be sequenced as the principal diagnosis because it is the condition chiefly responsible for the services provided during the current admission, even though the initial reason for admission was the hernia repair. The hernia repair, while documented, would be coded as a secondary diagnosis or procedure. The rationale for this sequencing is to accurately reflect the primary reason for the patient’s current encounter and the services rendered, which is crucial for both statistical reporting and reimbursement purposes, aligning with the emphasis on data integrity and compliance taught at Certified Coding Associate (CCA) University.

The core of this question lies in understanding the nuanced application of ICD-10-CM coding guidelines for external causes of morbidity, specifically when a patient sustains an injury due to an accident involving a motor vehicle and a stationary object. The scenario describes a driver of a passenger car colliding with a parked truck. According to ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.20.c.1.a, when a patient is admitted for a condition that is a sequela of an injury, the sequela code is assigned first, and the injury code is assigned as an additional code. However, this scenario describes the initial encounter for the injury itself, not a sequela. For accidents involving vehicles, the guidelines direct coders to use the appropriate V, W, X, or Y codes from Chapter 20. Specifically, V40-V49 are used for occupants of cars injured in collisions with other vehicles. V43.52XA denotes an “Occupant of car injured in collision with heavy transport vehicle, driver” for the initial encounter. The collision with a parked truck falls under the category of collision with another vehicle, even if stationary. The guidelines further specify that if the type of vehicle is not specified, or if the vehicle is stationary, a more specific code should be sought. However, in the absence of further detail about the truck’s classification beyond “parked truck,” the most appropriate initial classification for the driver of the passenger car is based on the impact with another vehicle. The question requires identifying the correct combination of codes that accurately reflects the circumstances of the injury. The primary diagnosis code will represent the injury itself, and the external cause code will describe how the injury occurred. The scenario specifies a driver of a passenger car, making the V43.52XA code appropriate for the initial encounter. The explanation of the external cause code is crucial. The collision with a parked truck is a collision with another vehicle. The guidelines for V codes indicate that collisions with stationary objects are coded based on the object’s nature. A parked truck, in this context, is considered another vehicle. Therefore, the external cause code should reflect this. The explanation of the correct approach involves identifying the principal diagnosis for the injury and then supplementing it with the external cause code that details the circumstances. The correct approach is to use a code from the S00-T88 range for the injury itself, followed by the V code for the motor vehicle accident. The specific V code for a driver of a car in a collision with another vehicle (even a parked one) is V43.52XA for the initial encounter. The explanation of the correct approach involves understanding that the ICD-10-CM guidelines prioritize specificity in external cause coding. When a driver of a passenger car is involved in a collision with another vehicle, even if stationary, the coding reflects this interaction. The V43.52XA code accurately captures the driver’s role and the type of vehicle involved in the collision. The explanation of the correct approach involves identifying the principal diagnosis for the injury and then supplementing it with the external cause code that details the circumstances. The correct approach is to use a code from the S00-T88 range for the injury itself, followed by the V code for the motor vehicle accident. The specific V code for a driver of a car in a collision with another vehicle (even a parked one) is V43.52XA for the initial encounter.

The scenario presented involves a patient admitted for an exacerbation of chronic obstructive pulmonary disease (COPD) and also diagnosed with pneumonia. The physician’s documentation clearly states the principal diagnosis as COPD exacerbation, with pneumonia being a secondary condition that influenced the patient’s hospital course and management. According to ICD-10-CM Official Guidelines for Coding and Reporting, when a condition arises during the hospital stay that is not related to the condition for which the patient was admitted, it is coded as a secondary diagnosis. However, in this case, the pneumonia is directly linked to the exacerbation of COPD, as indicated by the physician’s notes suggesting the pneumonia contributed to the severity of the COPD exacerbation. The guidelines further specify that if a condition is documented as affecting the management of the principal diagnosis, it should be sequenced as a secondary diagnosis. Specifically, for respiratory conditions, if pneumonia is present and exacerbates or is a complication of another respiratory condition like COPD exacerbation, it is coded as a secondary diagnosis. The principal diagnosis is the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital. In this context, the COPD exacerbation is the primary reason for admission. The pneumonia, while significant, is presented as a complication or contributing factor to the severity of the COPD exacerbation, necessitating its coding as a secondary diagnosis. Therefore, the correct coding sequence would list the COPD exacerbation as the principal diagnosis, followed by the pneumonia. This reflects the hierarchical relationship and the causal link described in the physician’s documentation and aligns with the fundamental principles of ICD-10-CM coding for co-existing conditions that influence patient care.

The scenario describes a patient presenting with symptoms suggestive of a urinary tract infection. The physician’s documentation notes dysuria, frequency, and suprapubic pain. A urinalysis confirms the presence of leukocytes and nitrites, and a urine culture identifies *Escherichia coli* as the causative agent. The physician also documents a history of recurrent UTIs and a current prescription for trimethoprim-sulfamethoxazole. To accurately code this encounter for Certified Coding Associate (CCA) University’s curriculum, which emphasizes adherence to ICD-10-CM guidelines and clinical documentation integrity, we must identify the principal diagnosis and any relevant secondary diagnoses or conditions. The principal diagnosis is the condition chiefly responsible for the encounter. In this case, the documented symptoms (dysuria, frequency, suprapubic pain) and the confirmed laboratory findings (leukocytes, nitrites, *E. coli*) clearly point to a urinary tract infection. The ICD-10-CM code for a urinary tract infection, unspecified, is N39.0. The documentation also specifies the causative organism, *Escherichia coli*. ICD-10-CM guidelines, particularly those related to infectious and parasitic diseases, often require coding to the highest level of specificity when an organism is identified. For UTIs, the presence of a specific organism can influence coding. While N39.0 is appropriate for an unspecified UTI, if the documentation strongly supports a specific type of UTI due to the identified organism, a more specific code might be considered. However, N39.0 is the most appropriate code for a general UTI diagnosis when the specific anatomical site within the urinary tract (e.g., cystitis, pyelonephritis) is not definitively stated as the primary focus beyond the general symptoms. The history of recurrent UTIs is a significant clinical factor but does not represent a current active problem requiring treatment during this specific encounter. Therefore, it would not typically be coded as a principal or secondary diagnosis unless it directly impacted the management of the current UTI or was a focus of care. The prescription for trimethoprim-sulfamethoxazole is a treatment modality and does not directly translate to an ICD-10-CM diagnosis code. Therefore, the most accurate and comprehensive coding for this encounter, reflecting the principal diagnosis as supported by the clinical documentation and laboratory findings, is N39.0. This aligns with the CCA’s focus on translating clinical information into accurate diagnostic codes according to established coding standards. The emphasis is on identifying the primary reason for the patient’s visit and ensuring the code reflects the documented condition.

The scenario describes a patient undergoing a complex surgical procedure, a radical nephrectomy with adrenalectomy and lymphadenectomy, for a malignant neoplasm of the kidney. The documentation indicates the presence of a secondary malignant neoplasm in the adrenal gland and metastasis to regional lymph nodes. For the primary diagnosis, the malignant neoplasm of the kidney is the principal reason for the encounter and the surgery. The ICD-10-CM code for malignant neoplasm of the kidney is C64.9. The documentation also specifies a secondary malignant neoplasm of the adrenal gland. The ICD-10-CM code for malignant neoplasm of the adrenal gland is C74.0. Since this is a secondary malignancy directly related to the primary condition and addressed during the same surgical encounter, it is coded as a secondary diagnosis. Furthermore, the documentation notes metastasis to regional lymph nodes. The ICD-10-CM coding guidelines state that when a malignancy has metastasized to regional lymph nodes, and the specific site of the lymph node is not documented, the coder should assign a code from category C77, Secondary and unspecified malignant neoplasm of lymph nodes. For regional lymph nodes, the appropriate code is C77.8, Secondary and unspecified malignant neoplasm of lymph nodes of abdomen and pelvis. This is also coded as a secondary diagnosis. The principal procedure performed is the radical nephrectomy with adrenalectomy and lymphadenectomy. In CPT coding, the radical nephrectomy is coded using 50230 (Nephrectomy, radical, with adrenalectomy). The lymphadenectomy, when performed in conjunction with a nephrectomy, is typically included unless it is extensive and separately documented. However, for the purpose of this question, we focus on the primary diagnosis coding. Therefore, the correct ICD-10-CM coding sequence for the diagnoses would be C64.9 (Malignant neoplasm of kidney, unspecified), followed by C74.0 (Malignant neoplasm of adrenal gland), and then C77.8 (Secondary and unspecified malignant neoplasm of lymph nodes of abdomen and pelvis). This sequence accurately reflects the principal diagnosis and the co-existing secondary malignancies and metastases that were addressed during the encounter, adhering to the principle of coding the principal diagnosis first.

The scenario describes a patient undergoing a complex surgical procedure. The primary diagnosis is established as “Severe Chronic Obstructive Pulmonary Disease exacerbation.” The surgical procedure is a “Right upper lobectomy with mediastinal lymph node dissection.” The surgeon also performed an “Exploratory laparotomy due to suspected intra-abdominal metastasis.” The key to selecting the correct principal diagnosis is to identify the condition that occasioned the admission of the patient to the hospital for care. In this case, the exacerbation of COPD necessitated the admission. While the lobectomy is a significant procedure, it was performed to address the underlying lung condition, which was exacerbated. The exploratory laparotomy, though performed, was secondary to the primary reason for admission and the main surgical intervention. Therefore, the principal diagnosis is the COPD exacerbation. The ICD-10-CM code for “Exacerbation of chronic obstructive pulmonary disease” is J44.1. The other procedures are coded separately, but the principal diagnosis is determined by the condition that led to the admission. Understanding the hierarchy of diagnoses and the guidelines for selecting the principal diagnosis is crucial for accurate coding, impacting reimbursement and statistical reporting, which are core competencies for Certified Coding Associates at Certified Coding Associate University. This aligns with the university’s emphasis on rigorous application of coding principles and understanding their downstream effects on healthcare operations.

The scenario describes a patient admitted for an exacerbation of chronic obstructive pulmonary disease (COPD) with an acute exacerbation of asthma. The physician’s documentation clearly states “acute exacerbation of COPD” and “acute asthma exacerbation.” According to ICD-10-CM Official Guidelines for Coding and Reporting, when a patient has both COPD and asthma, and the documentation indicates an exacerbation of both conditions, the coder must determine the principal diagnosis. In this case, the exacerbation of COPD is listed first in the physician’s statement, and it is a chronic condition that is currently exacerbated. The asthma exacerbation, while also present, is described as “acute.” The guidelines also emphasize coding to the highest level of specificity. For COPD with exacerbation, the code J44.1 (Chronic obstructive pulmonary disease with (acute) exacerbation) is appropriate. For acute asthma with exacerbation, the code J45.901 (Unspecified asthma with (acute) exacerbation) is appropriate. However, the question asks for the principal diagnosis. The physician’s documentation implies that the COPD exacerbation is the primary reason for admission, with the asthma exacerbation being a co-existing condition that is also exacerbated. Therefore, the principal diagnosis should reflect the COPD exacerbation. The ICD-10-CM guidelines for coding multiple conditions state that the principal diagnosis is the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital. Given the physician’s phrasing and the nature of chronic conditions, the acute exacerbation of COPD is the most appropriate principal diagnosis. The question requires understanding the hierarchy of diagnoses and the application of coding guidelines for exacerbations of chronic respiratory conditions. The correct approach involves identifying the primary reason for admission as documented by the physician and selecting the most specific ICD-10-CM code that reflects this condition.

The scenario presented involves a patient undergoing a complex surgical procedure for a malignant neoplasm of the sigmoid colon. The physician’s documentation indicates the removal of the sigmoid colon, a portion of the descending colon, and associated lymph nodes. The primary diagnosis is C18.7 (Malignant neoplasm of sigmoid colon). The operative report details a sigmoid colectomy with partial descending colectomy and lymphadenectomy. When coding for this scenario, the coder must consider the principal diagnosis and any secondary diagnoses that affect patient care, treatment, or management. The presence of metastatic disease in the lymph nodes is a critical factor that influences the complexity and management of the case. According to ICD-10-CM Official Guidelines for Coding and Reporting, secondary malignant neoplasms in lymph nodes that are related to the primary site are coded to the primary site’s neoplasm code, with an additional code to identify the secondary site if it is the focus of treatment or management. However, in this specific instance, the lymphadenectomy is performed as part of the treatment for the primary sigmoid colon cancer, and the documentation explicitly states the lymph nodes are “associated” with the primary neoplasm. Therefore, the most accurate coding approach is to reflect the primary malignancy and the extent of the surgical procedure. Given the options, the most appropriate coding sequence would prioritize the malignant neoplasm of the sigmoid colon as the principal diagnosis. The surgical procedure itself is not coded with ICD-10-CM; rather, ICD-10-CM codes describe the conditions treated. The question implicitly asks for the correct ICD-10-CM diagnosis coding. The presence of secondary malignant neoplasm in lymph nodes, when removed as part of the treatment for the primary site, is often captured by the primary site code itself, especially if the guidelines do not mandate a separate code for the lymph node involvement when it’s integral to the primary treatment. In this case, the malignant neoplasm of the sigmoid colon (C18.7) is the primary condition. The lymphadenectomy is a procedure, not a diagnosis to be coded with ICD-10-CM in this context. The question is designed to test the understanding of how to code related secondary sites when they are part of the primary treatment. The ICD-10-CM guidelines for neoplasms state that secondary malignant neoplasms in lymph nodes are coded to the primary site, and if the lymph node is the focus of treatment, a separate code for the secondary site may be used. However, in the context of a colectomy with lymphadenectomy for colon cancer, the lymph node involvement is typically considered an extension of the primary disease process. Therefore, focusing on the primary site of the malignant neoplasm of the sigmoid colon is paramount. The correct approach is to identify the most specific code for the primary malignancy.

The scenario describes a patient undergoing a diagnostic colonoscopy with polyp removal. The primary diagnosis is a history of colon polyps, which is a pre-existing condition. The colonoscopy itself is a procedure performed to investigate symptoms of intermittent abdominal pain and changes in bowel habits. During the procedure, a single adenomatous polyp is identified and removed. In ICD-10-CM coding, the principal diagnosis is defined as the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for inpatient care or for outpatient services. In this case, the intermittent abdominal pain and changes in bowel habits are the symptoms that led to the outpatient encounter for the colonoscopy. While the polyp is a significant finding, it was discovered during the investigation of these symptoms. Therefore, the symptoms are coded as the principal diagnosis. The adenomatous polyp, once identified and removed, becomes a secondary diagnosis. ICD-10-CM guidelines specify coding for polyps. For an adenomatous polyp, the appropriate code is K63.5 (Polyp of colon). The colonoscopy procedure itself is not coded using ICD-10-CM; it is coded using CPT (Current Procedural Terminology). However, the question asks for the ICD-10-CM diagnoses. Therefore, the correct coding sequence for the diagnoses would be the symptom codes followed by the code for the adenomatous polyp. The symptoms are intermittent abdominal pain and changes in bowel habits. A common code for intermittent abdominal pain is R10.84 (Generalized abdominal pain). Changes in bowel habits can be coded with K59.9 (Functional intestinal disorder, unspecified) or more specific codes if further detail is available, but for this scenario, focusing on the primary symptom of pain is most appropriate for the principal diagnosis. Given the options, the most accurate representation of the principal diagnosis being the symptom that led to the encounter, and the polyp being a secondary finding, is to list the symptom first. Let’s refine the symptom coding. Intermittent abdominal pain is best represented by R10.84. Changes in bowel habits, while present, might be considered part of the overall presentation leading to the pain. The adenomatous polyp is K63.5. The question implies a need to select the most appropriate principal diagnosis. The reason for the encounter was the symptoms. Considering the provided options, the correct approach is to identify the condition that occasioned the encounter. The patient presented with symptoms of intermittent abdominal pain and changes in bowel habits. These symptoms are the reason for the colonoscopy. Therefore, the symptom(s) should be sequenced as the principal diagnosis. The adenomatous polyp is a finding during the encounter, making it a secondary diagnosis. The calculation is conceptual, not numerical. It involves applying coding guidelines to determine the principal diagnosis. 1. Identify the reason for the encounter: Symptoms of intermittent abdominal pain and changes in bowel habits. 2. Determine the principal diagnosis: The condition chiefly responsible for occasioning the encounter. In this case, it’s the symptoms. 3. Identify secondary diagnoses: Conditions found during the encounter that are treated or monitored. Here, it’s the adenomatous polyp. 4. Select appropriate ICD-10-CM codes: R10.84 for generalized abdominal pain (representing intermittent abdominal pain) and K63.5 for polyp of colon. The correct sequence is the symptom code first, followed by the polyp code.

The core of this question lies in understanding the hierarchical structure of ICD-10-CM coding and the principle of assigning the principal diagnosis. The scenario describes a patient admitted for a specific condition (acute exacerbation of chronic obstructive pulmonary disease) that was directly influenced by an underlying, chronic condition (pulmonary fibrosis). The documentation clearly indicates that the pulmonary fibrosis is the underlying cause that led to the exacerbation. In ICD-10-CM, when a condition arises as a direct consequence of another condition, the underlying condition is often coded as the principal diagnosis if it is the reason for admission or significantly contributes to the patient’s care. In this case, while the acute exacerbation is the immediate reason for the hospital stay, the pulmonary fibrosis is the pre-existing, chronic condition that predisposes the patient to such exacerbations and is integral to understanding the overall clinical picture. The ICD-10-CM Official Guidelines for Coding and Reporting emphasize coding all conditions that coexist at the time of admission that affect patient care. When an exacerbation of a chronic condition is due to an underlying disease, the underlying disease should be sequenced first if it is the primary reason for the encounter or significantly impacts management. The pulmonary fibrosis (J84.10) is the foundational issue that makes the COPD exacerbation more severe or likely. The acute exacerbation of COPD (J44.1) is a manifestation of this underlying condition. Therefore, the correct coding sequence prioritizes the underlying cause.

The core of this question lies in understanding the hierarchical structure and specific coding conventions within ICD-10-CM, particularly as they apply to the concept of “complication.” When a condition is described as a complication of a procedure, the ICD-10-CM guidelines direct coders to assign codes that reflect this relationship. Specifically, Chapter 19 (Injury, poisoning and certain other consequences of external causes) and Chapter 20 (External causes of morbidity) contain specific guidance on coding complications. However, the fundamental principle for coding complications of care, whether surgical, medical, or a device, is to identify the specific nature of the complication and the condition it exacerbates or arises from. In the context of ICD-10-CM, a complication is often coded as a secondary diagnosis that directly relates to the primary condition or procedure. The ICD-10-CM Official Guidelines for Coding and Reporting provide explicit instructions for sequencing and selecting codes when complications are present. For instance, if a patient develops a post-operative infection following a knee replacement, the infection would be coded as a secondary diagnosis, and the knee replacement would be the primary reason for the encounter. The question probes the understanding of how ICD-10-CM handles these cause-and-effect relationships, emphasizing that the coding system is designed to capture the full clinical picture, including adverse events or complications arising from treatment or underlying conditions. The correct approach involves identifying the specific ICD-10-CM codes that accurately represent the complication and its relationship to the primary diagnosis or procedure, adhering strictly to the sequencing rules and tabular list instructions. This ensures that the patient’s medical record accurately reflects the clinical complexity and supports appropriate reimbursement and quality reporting.

The scenario describes a patient undergoing a complex surgical procedure involving both a primary repair of a ruptured abdominal aortic aneurysm and a concomitant aortobifemoral bypass graft. The primary procedure is the aneurysm repair, which is the central focus of the surgical intervention. The bypass graft, while significant, is performed in conjunction with and to facilitate the successful outcome of the aneurysm repair. In ICD-10-CM coding, the principle of “principal diagnosis” and “principal procedure” is paramount. The principal procedure is defined as the procedure performed for the condition that most requires the use of hospital resources. In this case, the ruptured abdominal aortic aneurysm is the condition necessitating the extensive resources and the primary surgical intervention. The aortobifemoral bypass graft is a secondary procedure performed to restore blood flow, directly related to the management of the aneurysm. Therefore, the aortobifemoral bypass graft would be coded as a secondary procedure, reflecting its supportive role in treating the principal diagnosis. The correct coding approach involves identifying the principal procedure that addresses the primary reason for the patient’s admission and then coding any secondary procedures that were performed during the same encounter. This ensures accurate representation of the patient’s care and the services rendered, which is fundamental to the integrity of healthcare data and reimbursement at Certified Coding Associate (CCA) University.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection (UTI) and a concurrent diagnosis of hypertension. The physician’s documentation notes the presence of bacteriuria, which is a key indicator for coding UTIs. The ICD-10-CM coding guidelines for UTIs specify that when bacteriuria is documented without a definitive diagnosis of a UTI, the coder should query the physician for clarification. However, if the physician explicitly documents “bacteriuria” as a condition, and it’s not linked to a specific UTI diagnosis, it should be coded as such. In this case, the physician has documented “bacteriuria” as a distinct finding. Therefore, the appropriate ICD-10-CM code for bacteriuria, not elsewhere classified, is N39.0 (Urinary tract infection, site not specified). The hypertension is a co-existing condition and should be coded separately as I10 (Essential (primary) hypertension). The question asks for the *primary* diagnosis that dictates the focus of the encounter, and while hypertension is present, the documented bacteriuria and the implied workup for it suggest it is the primary reason for the current encounter’s diagnostic focus. Therefore, the coding sequence should reflect the bacteriuria as the principal diagnosis.

The scenario describes a patient undergoing a complex surgical procedure. The primary diagnosis is a severe, chronic condition impacting the respiratory system, necessitating extensive surgical intervention. The surgeon’s documentation details a primary procedure to address this chronic condition, involving significant dissection and reconstruction of lung tissue. Additionally, the documentation notes a secondary, less complex procedure performed concurrently to manage a related but distinct complication, which involved a minimally invasive approach to clear obstructed airways. The question requires identifying the principal diagnosis and the principal procedure based on the provided clinical narrative and the established coding guidelines for ICD-10-CM and CPT. The principal diagnosis is the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital. In this case, the severe chronic respiratory condition is clearly the primary reason for the surgical admission and the extensive operative work. The principal procedure is the procedure performed for definitive treatment of the principal diagnosis. The extensive lung reconstruction directly addresses the chronic respiratory condition. The secondary procedure, while important for patient care, is described as managing a complication and is less extensive than the primary procedure. Therefore, the correct coding would reflect the chronic respiratory condition as the principal diagnosis and the lung reconstruction as the principal procedure. The other options represent incorrect sequencing of diagnoses or misidentification of the principal procedure based on the complexity and direct relationship to the primary reason for admission.

The scenario describes a patient presenting with symptoms indicative of an acute myocardial infarction (AMI). The physician’s documentation notes “chest pain, radiating to the left arm, diaphoresis, and shortness of breath.” The diagnostic workup includes an electrocardiogram (ECG) showing ST-segment elevation in leads II, III, and aVF, and elevated cardiac biomarkers (troponin). The patient undergoes percutaneous coronary intervention (PCI) with stent placement in the right coronary artery (RCA). To accurately code this encounter for Certified Coding Associate (CCA) University’s curriculum, we must identify the principal diagnosis and any secondary diagnoses or procedures. The principal diagnosis is the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital. In this case, the documented symptoms, ECG findings, and elevated cardiac biomarkers clearly point to an acute ST-elevation myocardial infarction (STEMI). The ICD-10-CM code for STEMI of the inferior wall, which is consistent with ST elevation in leads II, III, and aVF, is I21.19, ST elevation (STEMI) myocardial infarction involving other coronary artery of inferior wall. The documentation also mentions “hypertension” as a co-existing condition. Hypertension is a common comorbidity and should be coded if it affects patient care or management. The ICD-10-CM code for essential (primary) hypertension is I10. The procedure performed, percutaneous coronary intervention with stent placement in the right coronary artery, is coded using CPT. The CPT code for percutaneous transluminal coronary angioplasty (PTCA) with insertion of a stent into a single coronary artery is 92928. A modifier is needed to indicate the specific artery involved. For the right coronary artery, modifier -RC is used. Therefore, the procedure code is 92928-RC. The question asks for the most appropriate ICD-10-CM code for the principal diagnosis. Based on the clinical presentation and diagnostic findings, the most specific and accurate code for an inferior wall STEMI is I21.19. This code reflects the type of myocardial infarction (STEMI) and its specific location (inferior wall, involving other coronary artery). The other options represent less specific diagnoses or conditions not directly supported as the principal reason for admission. For instance, I21.3 is STEMI of unspecified site, which is less precise than I21.19 given the ECG findings. I20.0 is unstable angina, which is a different clinical entity than a STEMI. I51.9 is heart disease, unspecified, which is too general. Therefore, I21.19 is the most accurate principal diagnosis code.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection (UTI) and a concurrent diagnosis of type 2 diabetes mellitus. The physician’s documentation notes the presence of bacteriuria, which is a key element in coding UTIs. The ICD-10-CM coding guidelines specify that when a UTI is documented, and the specific causative organism is not identified, the coder should assign a code from category N39.0 (Urinary tract infection, site not specified). However, the documentation also explicitly states “bacteriuria without signs and symptoms of urinary tract infection.” This distinction is crucial. According to ICD-10-CM Official Guidelines for Coding and Reporting, FY 2023, Section I.B.14, “Bacteriuria, asymptomatic” is not assigned a code unless it is specifically addressed by a guideline or index entry. In this case, the physician’s documentation clearly differentiates between a symptomatic UTI and asymptomatic bacteriuria. Therefore, the primary diagnosis to be coded is the type 2 diabetes mellitus, as it is the more significant condition impacting the patient’s overall health and management. The asymptomatic bacteriuria, as documented, does not meet the criteria for a principal diagnosis or a secondary diagnosis that requires specific coding in the absence of a more definitive guideline or clinical significance. The presence of diabetes mellitus (E11.9) is a well-established risk factor and often a co-morbidity that influences patient care, making it the appropriate principal diagnosis.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection (UTI). The physician’s documentation notes “dysuria,” “frequency,” and “urgency,” all classic signs of a UTI. The physician also orders a urinalysis and urine culture, which are standard diagnostic tests for UTIs. The final diagnosis documented is “Acute cystitis without hematuria.” To accurately code this encounter for Certified Coding Associate (CCA) University’s curriculum, we must select the ICD-10-CM code that best represents the documented diagnosis. The ICD-10-CM coding system requires specificity. 1. **Identify the main term:** The main term is “Cystitis.” 2. **Locate “Cystitis” in the ICD-10-CM Index:** The index will lead to a specific code for cystitis. 3. **Consider sub-terms and qualifiers:** The documentation specifies “Acute” and “without hematuria.” The ICD-10-CM structure often includes sub-categories for the type of condition and associated symptoms or lack thereof. 4. **Navigate to the Tabular List:** Once the index provides a potential code, it’s crucial to verify it in the Tabular List. This step ensures that any necessary inclusion or exclusion notes, or further sub-categorization, are applied correctly. 5. **Apply coding guidelines:** ICD-10-CM guidelines emphasize coding to the highest level of specificity. In this case, “Acute cystitis without hematuria” is a precise description. Following these steps, the ICD-10-CM code N30.00 accurately reflects “Acute cystitis without hematuria.” N30.0 represents “Acute cystitis,” and the final zero indicates “without hematuria.” This code aligns with the physician’s documented diagnosis and the principles of accurate ICD-10-CM coding taught at Certified Coding Associate (CCA) University, emphasizing specificity and adherence to coding conventions. Understanding the relationship between clinical documentation and code assignment is fundamental for coders to ensure appropriate reimbursement and data integrity, core competencies for CCA graduates.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection (UTI) and a concurrent diagnosis of hypertension. The physician’s documentation notes the presence of dysuria, frequency, and suprapubic pain, along with a urinalysis confirming bacteriuria and pyuria, supporting the UTI diagnosis. The patient’s history also includes essential hypertension, which is being managed. To accurately code this encounter for Certified Coding Associate (CCA) University’s rigorous academic standards, a thorough understanding of ICD-10-CM coding guidelines is paramount. The primary reason for the encounter is the UTI. According to ICD-10-CM, infections of the urinary tract are classified under category N39.0 (Urinary tract infection, site not specified). The documentation clearly supports this diagnosis. The patient also has a history of essential hypertension, which is a co-existing condition. ICD-10-CM guidelines state that when a patient has a condition that is being treated or managed concurrently with another condition, and both are documented, both should be coded. Hypertension is classified under category I10 (Essential (primary) hypertension). Therefore, the correct coding sequence would reflect the UTI as the principal diagnosis, followed by the co-existing hypertension. This reflects the patient’s acute reason for seeking care while also capturing the chronic condition that influences their overall health status and management. The application of these coding principles is crucial for accurate data representation, reimbursement, and quality reporting, aligning with the core competencies emphasized at Certified Coding Associate (CCA) University. Accurate coding ensures that healthcare providers are appropriately reimbursed for services rendered and that public health data accurately reflects disease prevalence and patient comorbidities. This meticulous approach to coding is a cornerstone of the professional practice expected of Certified Coding Associates.

The scenario describes a patient undergoing a complex surgical procedure. The primary diagnosis is a malignant neoplasm of the ascending colon. The surgeon also performed a partial colectomy with ileoproctostomy. During the procedure, a perforation of the sigmoid colon was identified and repaired. The patient also has a history of type 2 diabetes mellitus, which is documented as impacting the management of the current condition. To determine the principal diagnosis, we must identify the condition chiefly responsible for occasioning the admission to the hospital after study and investigation. In this case, the malignant neoplasm of the ascending colon is the primary reason for the surgical intervention. Next, we consider secondary diagnoses. The perforation of the sigmoid colon, while repaired during the same operative session, is a distinct condition that required management. The type 2 diabetes mellitus is a co-morbidity that affects patient care. For inpatient coding, the ICD-10-CM Official Guidelines for Coding and Reporting are paramount. Guideline I.C.1.a.1 states that the principal diagnosis is the condition established after study to be chiefly responsible for occasioning the admission. Guideline I.C.1.a.2 addresses sequencing of diagnoses when a related condition is treated. Guideline I.C.1.a.3 emphasizes coding all conditions that coexist at the time of admission that affect patient care. Considering the provided information and the coding guidelines: The malignant neoplasm of the ascending colon (C18.2) is the principal diagnosis. The sigmoid colon perforation (K63.81) is a secondary diagnosis. The type 2 diabetes mellitus with hyperglycemia (E11.65) is also a secondary diagnosis. The question asks for the correct sequencing of these diagnoses for inpatient coding. The principal diagnosis is always listed first. The order of secondary diagnoses is determined by the circumstances of admission and the impact on patient care. In this scenario, the perforation, being an acute event requiring surgical repair during the same admission, would typically be sequenced before the chronic co-morbidity of diabetes, as it directly relates to the surgical management of the primary condition. However, the guidelines also state that secondary diagnoses that coexist at the time of admission and affect patient care should be sequenced based on the circumstances. Given that the diabetes is a significant factor influencing patient management and recovery, and the perforation is an intraoperative finding addressed during the primary procedure, the most appropriate sequencing reflects the primary reason for admission, followed by conditions that required management or significantly impacted care. Therefore, the correct sequence is: 1. Malignant neoplasm of ascending colon (C18.2) 2. Perforation of sigmoid colon (K63.81) 3. Type 2 diabetes mellitus with hyperglycemia (E11.65) This sequencing aligns with the principle of identifying the principal diagnosis first and then ordering secondary diagnoses to reflect their impact on the patient’s care during the admission. The presence of hyperglycemia associated with the diabetes further emphasizes its clinical significance.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection (UTI) and a concurrent diagnosis of hypertension. The physician’s documentation notes the presence of *Escherichia coli* as the causative agent for the UTI. When coding for this encounter at Certified Coding Associate (CCA) University, the primary focus is on accurately reflecting the patient’s conditions and the relationship between them, adhering to ICD-10-CM guidelines. The ICD-10-CM Official Guidelines for Coding and Reporting specify that when a UTI is documented as being caused by a specific organism, the code for the organism should be sequenced first, followed by the code for the UTI. In this case, the organism is *Escherichia coli*. The ICD-10-CM code for infection due to *Escherichia coli* in diseases classified elsewhere is **B96.20**. Following this, the guideline for UTIs states that if the causative organism is specified, the code for the organism should be sequenced first. The code for unspecified UTI is N39.0. However, since the organism is specified, and B96.20 is a code for an organism causing disease classified elsewhere, it is used as an additional code to identify the causative organism. The primary diagnosis for the UTI, given the documentation, would be N39.0, but the guidelines for coding infections due to specified organisms direct the sequencing. Specifically, for infections with specified organisms, the guideline states to use the appropriate code from Chapter 1 (Certain Infectious and Parasitic Diseases) or Chapter 14 (Diseases of the Genitourinary System) as appropriate, and then use an additional code from B95-B97 to identify the infectious agent. In this scenario, the UTI is the primary reason for the encounter, but the organism is specified. Therefore, the correct coding sequence involves identifying the UTI and then the organism. The ICD-10-CM index would lead to N39.0 for UTI. For *E. coli* as a causative agent, B96.20 is the appropriate code. The guidelines for coding UTIs when the organism is specified indicate that the code for the UTI should be sequenced first, followed by the code for the organism. However, a more nuanced interpretation of the guidelines, particularly when a specific organism is identified as the cause of a condition classified elsewhere, suggests that the organism’s code might be used to provide specificity. Upon review of the ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.1.a.2.a, it states that “When an infection is caused by an organism that is a reportable condition, the code for the infection should be sequenced first, followed by the code for the organism.” However, for UTIs, the guidelines are more specific. Section I.C.10.a.2 states, “If the causative organism is not known, assign code N39.0, Urinary tract infection, site not specified.” The scenario explicitly states *Escherichia coli* as the causative agent. The correct approach is to code the UTI first, and then the organism. The code for UTI is N39.0. The code for *Escherichia coli* as a bacterial infectious agent in diseases classified elsewhere is B96.20. The hypertension is a secondary diagnosis, coded as I10. Therefore, the correct sequencing for the primary condition and its causative agent is N39.0 followed by B96.20. The question asks for the most appropriate coding sequence for the UTI and its identified causative agent. The ICD-10-CM guidelines for coding UTIs when the organism is specified direct the coder to code the UTI first, followed by the organism. Thus, N39.0 for the UTI and B96.20 for the *E. coli* infection is the correct approach. The correct coding sequence for the urinary tract infection caused by *Escherichia coli*, as per ICD-10-CM guidelines, is to first code the condition itself, followed by the specific causative organism. The code for an unspecified urinary tract infection is N39.0. The code for *Escherichia coli* as a bacterial infectious agent in diseases classified elsewhere is B96.20. Therefore, the correct sequence is N39.0 followed by B96.20. This reflects the primary diagnosis and then the specific etiology, which is crucial for accurate data collection and reimbursement at institutions like Certified Coding Associate (CCA) University, where precise coding is paramount. Understanding these sequencing rules is fundamental to the practice of medical coding, ensuring that patient records are complete and that healthcare providers are appropriately reimbursed for services rendered. The hypertension, while present, is a secondary diagnosis and would be coded separately as I10. The emphasis here is on the correct ordering of codes for the primary condition and its identified cause, a core competency for any Certified Coding Associate (CCA) student.

The scenario describes a patient presenting with symptoms indicative of a urinary tract infection (UTI) and a concurrent diagnosis of hypertension. The physician’s documentation notes the presence of dysuria, frequency, and suprapubic pain, along with a history of elevated blood pressure. A urinalysis confirms bacteriuria and pyuria, supporting the UTI diagnosis. The physician also documents the patient’s existing hypertension. When coding this encounter for Certified Coding Associate (CCA) University’s curriculum, the primary focus is on accurately reflecting the patient’s conditions and the services provided. The ICD-10-CM coding guidelines require that the principal diagnosis be the condition chiefly responsible for the admission or encounter. In this case, the UTI is the acute condition that prompted the visit and required specific diagnostic and potentially therapeutic interventions. The documentation clearly supports a diagnosis of a UTI. The symptoms (dysuria, frequency, suprapubic pain) and the laboratory findings (bacteriuria, pyuria) are all consistent with this. Therefore, a code for UTI is appropriate. The patient also has a documented history of hypertension. According to ICD-10-CM coding conventions, when a patient has a condition that is managed or monitored during the encounter, and it is not the reason for the encounter, it is coded as a secondary diagnosis. Hypertension is a chronic condition that is often managed concurrently with other acute illnesses. The documentation explicitly states the patient has hypertension. Therefore, the coding should include a code for the UTI as the principal diagnosis and a code for hypertension as a secondary diagnosis. The specific ICD-10-CM codes would be selected based on the detailed documentation, but the principle of coding the acute condition first and then relevant co-existing conditions applies. The question tests the understanding of principal versus secondary diagnoses and the application of coding guidelines in a clinical context, which is a fundamental skill for Certified Coding Associates at CCA University. This approach ensures that the medical record accurately reflects the patient’s health status and the services rendered, impacting reimbursement and quality reporting.
