ICD-10 Code H93.09 – Unspecified degenerative and vascular disorders of ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.09 – Unspecified degenerative and vascular disorders of ear
What it is
This code describes a nonspecific ear disorder involving degenerative or vascular changes, but the record does not identify a more exact diagnosis. Use it when the provider documents an ear condition in this category without further detail.
Clinical signs
Clinical features vary; refer to documentation. Findings may be limited to a documented degenerative or vascular ear disorder without a clearer named condition, laterality, or site-specific detail.
When to use this code
Use H93.09 when the clinician documents an unspecified degenerative or vascular disorder of the ear and no more specific code is supported. It is appropriate when the chart lacks enough detail for a precise ear diagnosis. Check documentation if the note suggests a different ear disorder.
Do not use for
Do not use this code for clearly identified ear diseases, hearing loss, or tinnitus unless the provider specifically links them to an unspecified degenerative or vascular ear disorder. Do not assign it when a more specific diagnosis is documented.
Coding tip
Query for the exact ear diagnosis whenever the note only says “ear disorder,” because H93.09 is a fallback code.
