ICD-10 Code H93.099 – Unspecified degenerative and vascular disorders of unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.099 – Unspecified degenerative and vascular disorders of unspecified ear
What it is
This code identifies a degenerative or vascular disorder affecting the ear when the documentation does not specify the exact ear or the precise condition. Use it for nonspecific ear pathology that is not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. Notes may mention chronic ear changes, vascular abnormalities, or age-related degeneration, but the record must support an ear disorder rather than a separate, better-defined diagnosis.
When to use this code
Use H93.099 when the provider documents an unspecified degenerative or vascular disorder of the ear and no more specific code is available. It also fits when laterality is not stated and the chart does not identify a distinct underlying ear condition. Check documentation if the note only describes symptoms or a suspected disorder.
Do not use for
Do not use this code for hearing loss, tinnitus, infection, or trauma unless the provider specifically links them to an unspecified degenerative or vascular ear disorder. Do not code it when a more specific ear diagnosis is documented.
Coding tip
Before assigning H93.099, confirm that the record supports both “degenerative or vascular” and “unspecified ear” rather than a symptom-only or better-defined diagnosis.
