ICD-10 Code H71.00 – Cholesteatoma of attic, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H71.00 – Cholesteatoma of attic, unspecified ear
What it is
This code identifies a cholesteatoma located in the attic, or epitympanum, of the ear when the side is not specified. It refers to an abnormal skin growth in the middle ear space.
Clinical signs
Typical findings include persistent ear drainage, hearing loss, and evidence of a retraction pocket or destructive mass on otoscopic exam. Clinical features vary; refer to documentation.
When to use this code
Use H71.00 when the provider documents a cholesteatoma of the attic but does not specify right or left ear. This code fits confirmed diagnoses in outpatient, inpatient, or specialist notes. If the record identifies the ear laterality, code that more specific option instead.
Do not use for
Do not use this code for cholesteatoma in another ear location or when the attic is not documented. Check documentation if the provider only notes chronic otitis media or ear drainage without confirmed cholesteatoma.
Coding tip
Always look for laterality and exact anatomic site in the operative note, ENT assessment, or imaging report before selecting H71.00.
