Other nonrheumatic aortic valve disorders

This code represents various non-rheumatic conditions affecting the aortic valve that are not specifically categorized elsewhere. These disorders can include congenital anomalies, degenerative changes, or other acquired conditions leading to dysfunction of the aortic valve. It encompasses a range of structural or functional abnormalities impacting blood flow from the left ventricle.

Use this code for documented aortic valve disorders that are explicitly stated as non-rheumatic and do not have a more specific ICD-10-CM code. This includes conditions like bicuspid aortic valve without stenosis or insufficiency specified, or other congenital malformations not classified as stenosis or insufficiency. Documentation should clearly indicate the non-rheumatic etiology and the specific nature of the aortic valve disorder.

• Ensure the documentation explicitly states "non-rheumatic" and that no more specific code (e.g., for stenosis or insufficiency) is applicable.
• Avoid using this code if a more precise diagnosis, such as congenital aortic stenosis (Q23.0) or aortic valve insufficiency (I35.1), is documented.
• Consider sequencing this code after a primary cardiac condition if the aortic valve disorder is a secondary finding or complication.
