For a patient with hypertension, heart failure, and end-stage renal disease, which codes would be appropriate?

The selected codes I13.2, I50.9, and N18.6 are the most appropriate for a patient with hypertension, heart failure, and end-stage renal disease due to the specificity and accuracy they provide in capturing the patient's full clinical picture.

I13.2 is used for hypertension with heart and chronic kidney disease, indicating the presence of both hypertension and renal disease, specifically associated with heart disease. This code captures the interaction between these conditions, which is vital for understanding the comprehensive state of the patient's health.

I50.9 denotes heart failure, unspecified, which is suitable here as it does not require specification of the type or acuity of heart failure. Given that the question does not provide specific details regarding the heart failure type, this code is appropriate.

N18.6 refers to end-stage renal disease, accurately describing the severe state of renal impairment that requires consideration in care and management plans. Using this code ensures that the severity of the renal condition is recognized.

In contrast, the other combinations either misclassify the conditions or do not represent the severity needed for correct coding, making them less suitable. The correct answer comprehensively addresses all the significant health issues of the patient, reflecting the complexity of their clinical situation.
