ICD-10 Code H95.01 – Recurrent cholesteatoma of postmastoidectomy cavity, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.01 – Recurrent cholesteatoma of postmastoidectomy cavity, right ear
What it is
H95.01 identifies a recurrent cholesteatoma that develops in the postmastoidectomy cavity of the right ear. Use it when documentation specifies recurrence after prior mastoid surgery.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include chronic ear drainage, debris in the mastoid cavity, or evidence of recurrent keratinizing epithelium on otologic examination.
When to use this code
Use this code when the record clearly states recurrent cholesteatoma in the right postmastoidectomy cavity. It applies to postoperative recurrence, not to a first-time cholesteatoma or unspecified ear disease. If laterality or recurrence is not documented, check documentation before coding.
Do not use for
Do not use this code for cholesteatoma of the middle ear, external ear, or unspecified ear without a postmastoidectomy cavity. Also avoid it when the chart does not confirm right-sided recurrence.
Coding tip
Confirm both recurrence and right ear laterality in the operative or ENT note before assigning H95.01.
