Answer: The correct procedure code is 69320 (Reconstruction external auditory canal for congenital atresia, single stage), and the diagnosis is 744.03 (Congenital anomaly of middle ear except ossicles). Once ICD-10 goes into effect, the diagnosis code will change to Q16.4 (Other congenital malformations of middle ear).
