ICD-10 Code H80.92 – Unspecified Otosclerosis, Left Ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H80.92 – Unspecified otosclerosis, left ear
What it is
H80.92 identifies otosclerosis affecting the left ear when the record does not specify the type. It refers to abnormal bone remodeling in the otic capsule that can impair sound conduction or hearing.
Clinical signs
Common findings include progressive hearing loss, often conductive, and sometimes tinnitus. Clinical features vary; refer to documentation, and confirm that the left ear is the site involved.
When to use this code
Use H80.92 when the provider documents otosclerosis in the left ear but does not state whether it is conductive, cochlear, or another specified form. It also fits when the note confirms otosclerosis and laterality, but the subtype remains unspecified. Check documentation if both ears are mentioned.
Do not use for
Do not use this code if the record specifies another otosclerosis type or a different ear. Do not assign it for nonspecific hearing loss without documented otosclerosis.
Coding tip
Verify laterality and subtype in the operative note, audiology report, or assessment before selecting H80.92.
