Cochlear otosclerosis, right ear

This code describes the presence of otosclerosis affecting the cochlea of the right ear. Cochlear otosclerosis is a form of otosclerosis where the abnormal bone growth primarily involves the otic capsule surrounding the cochlea, leading to sensorineural hearing loss due to its impact on the inner ear structures.

Use this code when documentation specifies cochlear otosclerosis affecting the right ear. This diagnosis is typically made based on audiometric findings (sensorineural hearing loss), imaging studies (CT scan showing cochlear involvement), and clinical presentation.

• Ensure documentation explicitly states "cochlear otosclerosis" and specifies the "right ear."
• Do not confuse with fenestral otosclerosis (H80.0-) or retrofenestral otosclerosis (H80.1-) unless cochlear involvement is also documented.
• Code any associated hearing loss separately, linking it to the otosclerosis as appropriate.
