Other congenital malformations of pulmonary artery

This code represents various congenital structural abnormalities of the pulmonary artery that are not specifically classified elsewhere. These malformations can include conditions such as hypoplasia, atresia, or abnormal branching patterns of the main pulmonary artery or its major branches, impacting blood flow to the lungs.

Use this code for documented congenital anomalies of the pulmonary artery that do not have a more specific ICD-10-CM code. This applies when imaging studies (e.g., echocardiogram, CT angiography, MRI) or surgical findings confirm a malformation like an aberrant origin of a pulmonary artery branch or a diffuse hypoplasia not meeting criteria for other specified codes.

• Ensure documentation clearly specifies a congenital malformation of the pulmonary artery.
• Always review for more specific codes within the Q25.7 category before assigning this "other" code.
• 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.
