ICD-10 Code H80.83 – Other otosclerosis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H80.83 – Other otosclerosis, bilateral
What it is
H80.83 identifies otosclerosis affecting both ears when the documentation specifies another form of otosclerosis. It refers to abnormal bone remodeling in the middle ear that can interfere with sound conduction.
Clinical signs
Common findings include progressive conductive hearing loss, often bilateral, and sometimes tinnitus. Clinical features vary; refer to documentation for the exact type and laterality.
When to use this code
Use this code when the provider documents bilateral otosclerosis and does not specify a more precise subtype. It is appropriate for confirmed diagnoses in outpatient, inpatient, or specialist ear evaluations. If the record names a different otosclerosis category, code that instead.
Do not use for
Do not use H80.83 for unilateral otosclerosis or for hearing loss without documented otosclerosis. Check documentation when the laterality or subtype is unclear.
Coding tip
Verify both laterality and the exact otosclerosis description before assigning H80.83.
