Other anomalies of ribs and sternum

This code represents congenital malformations affecting the ribs and sternum that are not classified elsewhere. These anomalies can include various structural defects such as bifid ribs, absent ribs, pectus excavatum (funnel chest), pectus carinatum (pigeon chest), and sternal clefts. These conditions are present at birth and can range from asymptomatic to causing significant respiratory or cardiac compromise.

Use this code when documentation specifies a congenital anomaly of the ribs or sternum that is not more specifically categorized by another ICD-9-CM code. This includes conditions like pectus deformities, rib fusions, or other structural abnormalities identified through physical examination, imaging studies (e.g., X-ray, CT scan), or genetic testing.

• Differentiate between congenital and acquired chest wall deformities; this code is strictly for congenital conditions.
• For pectus excavatum or carinatum, ensure the documentation explicitly states "congenital" if not otherwise clear.
• Consider additional codes for any associated symptoms or complications, such as respiratory distress or cardiac displacement, if documented.
