AHA Coding Clinic® for ICD-9 - 2011 Issue 4; VOLUMES 1 & 2 NEW/REVISED CODES
Pulmonary Artery Anomalies
Effective October 1, 2011, code 747.31 has been created for pulmonary artery coarctation and atresia. Coarctation refers to narrowing or stenosis. Narrowing of the main pulmonary artery or its branches makes it difficult for blood that is deficient in oxygen to pass from the right ventricle to the lungs to get the oxygen that is necessary for the body. The heart becomes overworked when it has to pump harder to get the blood into the lungs. A moderate or severe degree of pulmonary artery stenosis can lead to pulmonary hypertension at rest or during exercise. Pulmonary artery stenosis...

Article Overview
This article explains a set of pulmonary artery and pulmonary circulation anomalies and notes related diagnosis code changes effective October 1, 2011. It is aimed at coders and other revenue-cycle professionals who need to understand the scope of these conditions, the affected diagnosis code categories, and the general procedural context discussed in the article. The content also includes a short example involving diagnostic workup and an endovascular treatment scenario.
Why This Topic Matters
Pulmonary vascular abnormalities can affect both diagnosis coding and procedure reporting, especially when the condition is congenital or involves endovascular treatment. The article helps readers recognize the topic area and the coding framework discussed for these anomalies.
