ICD-10 Code H71.3 – Diffuse Cholesteatosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H71.3 – Diffuse cholesteatosis
What it is
H71.3 identifies diffuse cholesteatosis, a condition involving widespread abnormal cholesteatoma-like tissue in the middle ear or related structures. Use the code when documentation specifically describes diffuse cholesteatosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include chronic ear disease, persistent drainage, hearing loss, or destructive middle ear changes noted on exam or imaging.
When to use this code
Use H71.3 when the provider documents diffuse cholesteatosis by name. It is appropriate when the record supports a diffuse, widespread lesion rather than a localized or unspecified ear condition. Check documentation if the note only mentions cholesteatoma broadly.
Do not use for
Do not use this code for simple otitis media, nonspecific ear discharge, or other ear disorders without documented diffuse cholesteatosis. If the diagnosis is different or unclear, check documentation.
Coding tip
Code only from the provider’s stated diagnosis; do not infer diffuse cholesteatosis from symptoms or imaging alone.
