ICD-10 Code H80.81 – Other otosclerosis, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H80.81 – Other otosclerosis, right ear
What it is
H80.81 identifies otosclerosis affecting the right ear, with features that do not fit a more specific otosclerosis category. It is a diagnosis used when the chart documents right-sided disease.
Clinical signs
Typical findings include progressive conductive hearing loss and reduced hearing on the affected side. Clinical features vary; refer to documentation.
When to use this code
Use H80.81 when the provider documents other otosclerosis in the right ear and the record supports laterality. Code it for confirmed right-ear otosclerosis, even if the note does not describe all audiologic details. Check documentation if the term is vague or bilateral disease is mentioned.
Do not use for
Do not use this code for otosclerosis involving the left ear, both ears, or unspecified laterality. Do not assign it when the record only mentions hearing loss without a documented otosclerosis diagnosis.
Coding tip
Confirm the ear and the exact otosclerosis wording before coding, because laterality drives the final code.
