ICD-10 Code H71.11 – Cholesteatoma of tympanum, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H71.11 – Cholesteatoma of tympanum, right ear
What it is
This code identifies a cholesteatoma located in the tympanum of the right ear. It refers to an abnormal growth of skin-like tissue in the middle ear space, not the outer ear canal.
Clinical signs
Typical findings include chronic ear drainage, hearing loss, and a visible or suspected middle ear mass. Clinical features vary; refer to documentation.
When to use this code
Use H71.11 when the provider documents cholesteatoma specifically in the right tympanum or right middle ear. It also applies when imaging, otoscopy, or operative findings clearly localize the lesion to that site. Check documentation if laterality or exact location is unclear.
Do not use for
Do not use this code for cholesteatoma in the left ear, bilateral disease, or unspecified ear. Avoid it if the record only mentions chronic otitis media without confirmed cholesteatoma.
Coding tip
Confirm both laterality and anatomic site before assigning H71.11.
