ICD-10 Code H71.93 – Unspecified cholesteatoma, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H71.93 – Unspecified cholesteatoma, bilateral
What it is
H71.93 identifies cholesteatoma in both ears when the record does not specify the exact type. It refers to an abnormal growth of skin-like tissue in the middle ear that can damage nearby structures.
Clinical signs
Common findings include chronic ear drainage, hearing loss, and a history of recurrent ear disease. Clinical features vary; refer to documentation for laterality, extent, and any associated complications.
When to use this code
Use H71.93 when the provider documents bilateral cholesteatoma but does not identify a more specific type. Apply it when both ears are involved and the note only supports an unspecified diagnosis. Check documentation if the record suggests a different cholesteatoma category or laterality.
Do not use for
Do not use this code for cholesteatoma limited to one ear or for a more specific cholesteatoma type. If the documentation identifies another ear condition without cholesteatoma, choose the documented diagnosis instead.
Coding tip
Verify both laterality and specificity in the operative note, consult, or assessment before assigning H71.93.
