Attic perforation of tympanic membrane, bilateral

This code signifies a hole or defect in the pars flaccida (attic) region of both eardrums. This perforation allows for direct communication between the external ear canal and the middle ear space, potentially leading to recurrent infections and hearing loss.

Apply this code when documentation explicitly states a bilateral attic perforation of the tympanic membrane. This is typically diagnosed via otoscopy and may be associated with chronic otitis media.

• Ensure the documentation specifies "attic" or "pars flaccida" and "bilateral" to support this specific code.
• Distinguish from perforations of the pars tensa, which are coded differently.
• Code any associated chronic otitis media or hearing loss separately.
