Rheumatic aortic stenosis with insufficiency

This code signifies a heart valve disorder where the aortic valve, due to rheumatic fever, is both narrowed (stenosis) and unable to close completely (insufficiency or regurgitation). This dual pathology impairs blood flow from the left ventricle to the aorta and causes blood to leak back into the ventricle.

Apply this code when documentation explicitly states a diagnosis of rheumatic aortic valve disease presenting with both stenotic and insufficient features. This is typically supported by echocardiogram findings and a patient history consistent with rheumatic fever.

• Ensure documentation specifies a rheumatic etiology; otherwise, non-rheumatic aortic stenosis with insufficiency would be coded differently.
• Do not confuse with isolated rheumatic aortic stenosis or isolated rheumatic aortic insufficiency; this code requires both conditions to be present.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting treatment.
