ICD-10 Code H71.0 – Cholesteatoma of attic (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H71.0 – Cholesteatoma of attic
What it is
H71.0 identifies a cholesteatoma located in the attic, the upper part of the middle ear. It is an abnormal growth of skin-like tissue that can erode nearby structures.
Clinical signs
Typical findings include chronic ear discharge, hearing loss, and a retraction pocket or debris in the attic on exam. Clinical features vary; refer to documentation.
When to use this code
Use H71.0 when the record specifically documents an attic cholesteatoma, also called epitympanic cholesteatoma. Apply it when the provider identifies the attic as the site, whether by otoscopy, imaging, or operative note.
Do not infer the site from a general cholesteatoma diagnosis. If the documentation only says “cholesteatoma” without location, check documentation before coding.
Do not use for
Do not use H71.0 for cholesteatoma in another middle-ear location or for nonspecific ear debris. Check documentation if the note does not confirm the attic site.
Coding tip
Always match the code to the documented anatomic site, not just the disease name.
