Unspecified anomaly of ear

This code signifies a congenital malformation of the ear that is not further specified as to its exact nature or location. It encompasses any birth defect affecting the external, middle, or inner ear when more precise diagnostic information is unavailable. This could include structural abnormalities present at birth.

Use this code when the medical record indicates a congenital anomaly of the ear, but the physician documentation does not provide sufficient detail to assign a more specific ICD-9-CM code (e.g., microtia, anotia, preauricular sinus). It is appropriate when the anomaly is noted but not fully characterized.

• Avoid using this code if a more specific congenital anomaly of the ear (e.g., 744.0-744.2, 744.8) can be identified from the documentation.
• Query the provider for further clarification if the documentation is vague regarding the specific type of ear anomaly.
• This code should be used as a last resort when no other specific congenital ear anomaly code applies.
