ICD-10 Code H95.112 – Chronic inflammation of postmastoidectomy cavity, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.112 – Chronic inflammation of postmastoidectomy cavity, left ear
What it is
This code identifies long-term inflammation in the mastoidectomy cavity of the left ear after surgery. Use it when the record specifically documents chronic inflammatory change in that postoperative space.
Clinical signs
Findings may include persistent drainage, irritation, or recurrent inflammation in the postmastoidectomy cavity. Clinical features vary; refer to documentation.
When to use this code
Use H95.112 when the clinician documents chronic inflammation affecting the left postmastoidectomy cavity. It fits postoperative ear records that describe ongoing cavity inflammation rather than an acute infection or a general ear disorder. Verify laterality and chronicity in the note.
Do not use for
Do not use this code for acute postoperative infection, nonspecific otitis, or mastoid disease without documentation of a postmastoidectomy cavity. Check documentation if the side or chronic nature is unclear.
Coding tip
Confirm the left-sided postoperative cavity is named explicitly, because laterality is built into this code.
