ICD-10 Code H95.02 – Recurrent cholesteatoma of postmastoidectomy cavity, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.02 – Recurrent cholesteatoma of postmastoidectomy cavity, left ear
What it is
This code identifies a recurrent cholesteatoma that has developed again in the left postmastoidectomy cavity. It reflects abnormal skin-like tissue in a previously operated mastoid space.
Clinical signs
Typical findings include persistent or recurrent ear drainage, debris in the mastoid cavity, and evidence of cholesteatoma on otologic exam. Clinical features vary; refer to documentation.
When to use this code
Use H95.02 when the record clearly states recurrent cholesteatoma in the left postmastoidectomy cavity. You may also use it when operative, ENT, or imaging documentation confirms recurrence after prior mastoid surgery. If the side or recurrence is not documented, check documentation before coding.
Do not use for
Do not use this code for a first-time cholesteatoma or for disease in the right ear or unspecified ear. Do not assign it when the note only mentions mastoid cavity infection or postoperative debris without recurrent cholesteatoma.
Coding tip
Verify both laterality and recurrence in the ENT record before assigning H95.02.
