Pectus carinatum

This code represents pectus carinatum, also known as pigeon chest, a congenital chest wall deformity characterized by an outward protrusion of the sternum and costal cartilages. This malformation results in an abnormally prominent anterior chest wall, which can vary in severity and may be symmetrical or asymmetrical.

Use this code when documentation clearly indicates a diagnosis of pectus carinatum. This typically applies to patients presenting with the characteristic outward sternal bowing, often identified during physical examination. Supporting documentation includes physician notes detailing the physical findings and diagnosis.

• Differentiate from pectus excavatum (funnel chest), which is an inward depression of the sternum.
• Consider additional codes for any associated symptoms or complications, such as respiratory compromise, if documented.
• Ensure the documentation specifies "carinatum" to avoid confusion with other chest wall deformities.
