ICD-10 Code H95.1 – Other disorders of ear and mastoid process following mastoidectomy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.1 – Other disorders of ear and mastoid process following mastoidectomy
What it is
Use this code for ear or mastoid problems that occur after a mastoidectomy and do not fit a more specific postprocedural diagnosis. It identifies a complication or residual disorder linked to the surgery.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record should show a prior mastoidectomy plus a documented ear or mastoid abnormality, such as postoperative pain, drainage, infection, or structural change.
When to use this code
Assign H95.1 when the provider documents a disorder of the ear or mastoid process as a consequence of mastoidectomy and no more specific code applies. Use it for postoperative findings that are clearly tied to the surgery. Check documentation for laterality, if relevant, and whether the condition is a complication or residual effect.
Do not use for
Do not use this code for routine aftercare or uncomplicated recovery after mastoidectomy. If the chart identifies a different, more specific postoperative ear or mastoid diagnosis, code that condition instead.
Coding tip
Confirm the operative history and the provider’s causal link to mastoidectomy before selecting H95.1.
