What is the correct diagnostic coding for a patient diagnosed with acute systolic heart failure due to hypertension with CKD stage 4?

The correct answer reflects a thorough understanding of the diagnostic coding guidelines for the specified conditions. In this case, the coding appropriately identifies the underlying causes and the severity of the patient’s conditions.

The code I13.0 pertains specifically to heart failure due to hypertension, where the patient presents with acute systolic heart failure—a critical association. The second code, I50.21, accurately designates the type of heart failure, confirming that it is acute systolic heart failure. The final code, N18.4, indicates chronic kidney disease stage 4, which is aligned with the patient’s condition of CKD.

This answer highlights the correct relationship between the cardiovascular condition (acute systolic heart failure) and its etiology (hypertension), while also accurately representing the severity of the chronic kidney disease. Each component of the code is essential for providing a comprehensive view of the patient’s health status, ensuring that all significant conditions are documented.

Other options may include incorrect codes for the classifications or miss crucial components needed for a complete diagnosis, potentially leading to inadequate representation of the patient’s health status in medical records. Therefore, the selection of B is the most comprehensive and accurate representation for the given clinical scenario.
