Adhesive middle ear disease, bilateral

This code signifies a condition where fibrous adhesions form within both middle ear cavities, restricting the movement of the ossicles and eardrum. This can lead to conductive hearing loss and a sensation of ear fullness due to impaired sound transmission.

Use this code when documentation explicitly states "adhesive middle ear disease" affecting both ears. This diagnosis is typically made based on otoscopic examination, audiometry showing conductive hearing loss, and sometimes tympanometry revealing reduced eardrum mobility.

• Ensure the documentation clearly specifies "bilateral" involvement; otherwise, use a unilateral code.
• Distinguish from otosclerosis (H80.-) or other causes of conductive hearing loss.
• Code any associated hearing loss (e.g., H90.0-) as a secondary diagnosis.
