ICD-10 Code H71.32 – Diffuse cholesteatosis, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H71.32 – Diffuse cholesteatosis, left ear
What it is
H71.32 identifies diffuse cholesteatosis affecting the left ear. Use it when documentation states this specific ear-site diagnosis and not a more general middle ear disorder.
Clinical signs
Clinical features vary; refer to documentation. Cholesteatosis is typically associated with abnormal keratinizing tissue in the ear and may be noted on otologic examination or imaging.
When to use this code
Use this code when the provider documents diffuse cholesteatosis limited to the left ear. It is appropriate for outpatient, inpatient, or specialty ear, nose, and throat records when the diagnosis is confirmed.
If the note only says cholesteatosis without laterality, check documentation before assigning a code. Code the documented site exactly as recorded.
Do not use for
Do not use this code for right ear, bilateral disease, or unspecified ear involvement. Do not apply it to other chronic ear conditions unless cholesteatosis is specifically documented.
Coding tip
Verify laterality in the operative note, assessment, or imaging report before coding H71.32.
