What is the icd 9 code for single stage reconstruction of the right external auditory canal for congenital atresia?

The ICD-9 code for congenital atresia of the external auditory canal is 744.1. However, ICD-9 does not specifically code for surgical procedures like a single-stage reconstruction. You would typically need to refer to procedural codes (CPT) for the specific surgical intervention. For accurate billing and coding, it's essential to consult current coding guidelines and resources.
