ICD-10 Code H71.91 – Unspecified cholesteatoma, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H71.91 – Unspecified cholesteatoma, right ear
What it is
This code identifies cholesteatoma in the right ear when the record does not specify the exact type. It refers to an abnormal skin growth in the middle ear that can damage nearby structures.
Clinical signs
Typical findings include chronic ear drainage, hearing loss, or a visible/reported middle ear mass. Clinical features vary; refer to documentation.
When to use this code
Use H71.91 when the provider documents cholesteatoma in the right ear but does not name a more specific type or site detail. It is appropriate for confirmed diagnoses in progress notes, operative reports, or specialist assessments. If the record later specifies a more exact cholesteatoma type, code that instead.
Do not use for
Do not use this code for cholesteatoma of the left ear, bilateral disease, or when documentation identifies a different ear disorder. Check documentation if the side or diagnosis is unclear.
Coding tip
Assign the most specific cholesteatoma code supported by the note; if laterality or type is missing, H71.91 is the fallback only for the right ear.
