Question

What is coded in addition to category I12, Hypertensive chronic kidney disease when both huypertension and chronic kidney disease are present in a patient?

When a ptient has hypertensive retionopathy, what is the second code that should be used with subcategory I35.0. Background retinopathy and retinal vascular changes?

What assumption can be made by the coder when a physician describes a patient has having atherosclerotic coronary artery disease with angina?

Answer 1

I12.0 is the code that indicates hypertensive chronic kidney disease. It indicates the end stage kidney disease caused due to the hypertension.

H35.03 is the subcategory code indicating hypertensive retinopathy.

414.0 is the code for the atherosclerotic coronary artery disease to specify angina code 411.1 or 413.9 is used based on the type of angina.

For CAD associated with hypertension have another code in range of 150.0

Hence the coder may have the confusion to code CAD independently or to code it to associate with hypertension.

These are the codes for the conditions specified above.
