Cochlear otosclerosis, bilateral

AIClinical Context

Clinical Description

This code signifies the presence of otosclerosis affecting the cochlea in both ears. Cochlear otosclerosis is a progressive bone remodeling disorder of the otic capsule that can lead to sensorineural hearing loss due to its impact on the inner ear structures.

When to Use

Apply this code when documentation explicitly states bilateral cochlear otosclerosis as the cause of hearing impairment. This diagnosis is typically supported by audiometric findings consistent with sensorineural hearing loss and imaging (e.g., CT scan) demonstrating otosclerotic foci within the cochlea.

Coding Tips

Ensure the documentation specifies "cochlear" involvement, not just general otosclerosis.
Verify laterality; this code is specifically for bilateral involvement.
Do not confuse with conductive otosclerosis (H80.0-) or mixed otosclerosis (H80.1-).
