Conductive hearing loss, bilateral

This code signifies a type of hearing loss affecting both ears where sound transmission to the inner ear is impaired. This impairment typically results from issues in the outer or middle ear, such as blockages or damage to the ossicles.

Apply this code when documentation clearly indicates a conductive hearing loss impacting both the left and right ears. This diagnosis is often supported by audiometry results showing an air-bone gap in both ears, along with clinical findings consistent with middle ear pathology.

• Ensure documentation specifies "bilateral" involvement; otherwise, use a unilateral code or unspecified if laterality is not documented.
• Distinguish from sensorineural hearing loss (H90.3-H90.5) where the inner ear or auditory nerve is affected.
• Code any underlying cause of the conductive hearing loss (e.g., otitis media, otosclerosis) in addition to this code.
