Question: Which codes should I report for aortic valve stenosis and mitral valve regurgitation?
Answer: Code 396.2 (Mitral valve insufficiency and aortic valve stenosis) covers both aortic valve stenosis and mitral valve regurgitation.
Try this: Look up "regurgitation, mitral valve" in the ICD-9 index. It directs you to "see also, Insufficiency, mitral." The entry "Insufficiency, mitral, with aortic (valve) stenosis or obstruction," indicates 396.2 is the correct code to describe both conditions.
