Other nonrheumatic pulmonary valve disorders

This code signifies a non-rheumatic condition affecting the pulmonary valve that is not specifically classified elsewhere. It encompasses various structural or functional abnormalities of the pulmonary valve, excluding those caused by rheumatic fever. These disorders can impact blood flow from the right ventricle to the pulmonary artery.

Use this code for documented pulmonary valve disorders such as congenital pulmonary valve anomalies (e.g., dysplastic pulmonary valve, bicuspid pulmonary valve) not otherwise specified, or acquired non-rheumatic pulmonary valve insufficiency or stenosis when a more specific code is unavailable. Documentation should clearly indicate a pulmonary valve disorder and explicitly rule out a rheumatic origin.

• Always seek a more specific code if available for the exact pulmonary valve disorder (e.g., congenital pulmonary valve stenosis Q22.1).
• Ensure documentation explicitly states "non-rheumatic" or provides sufficient detail to exclude rheumatic etiology.
• Do not use for rheumatic pulmonary valve disease (I07.0-I07.9) or congenital pulmonary valve stenosis/atresia (Q22.1-Q22.3) if a more precise congenital code is applicable.
