Congen malform of ear causing impairment of hearing, unsp

This code signifies a birth defect affecting the ear's structure that results in some degree of hearing loss, where the specific type of malformation is not documented. It indicates an anatomical abnormality present at birth that interferes with auditory function.

Apply this code when documentation confirms a congenital ear malformation causing hearing impairment, but the specific nature of the malformation (e.g., microtia, atresia, anotia) is not specified. This code is appropriate when the physician notes "congenital ear malformation with hearing loss, type unspecified" or similar.

• Do not use this code if a more specific congenital ear malformation code (Q16.0-Q16.8) can be assigned based on documentation.
• Always code the associated hearing loss (e.g., H90.-, H91.-) in addition to this code.
• Query the provider for more specific details regarding the ear malformation if available, to allow for more precise coding.
