ICD-10 Code H95.119 – Chronic inflammation of postmastoidectomy cavity, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.119 – Chronic inflammation of postmastoidectomy cavity, unspecified ear
What it is
H95.119 identifies chronic inflammation in a postmastoidectomy cavity when the affected ear is not specified. Use it for persistent inflammatory changes in the surgical mastoid cavity after mastoid surgery.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include ongoing cavity inflammation, drainage, debris, or recurrent irritation in the postmastoidectomy space.
When to use this code
Use H95.119 when the record states chronic inflammation of a postmastoidectomy cavity and does not name the right or left ear. It may also fit follow-up notes describing persistent postoperative cavity inflammation. If the documentation specifies the ear, use the more specific code.
Do not use for
Do not use this code for acute postoperative infection, nonspecific otitis, or mastoid disease without a documented postmastoidectomy cavity. Check documentation if the record does not clearly identify chronic inflammation.
Coding tip
Confirm both chronicity and the postmastoidectomy cavity before assigning H95.119.
