ICD-10 Code H95.89 – Other postprocedural complications and disorders of the ear and mastoid process, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.89 – Other postprocedural complications and disorders of the ear and mastoid process, not elsewhere classified
What it is
This code identifies ear or mastoid problems that occur after a procedure and do not fit a more specific diagnosis. Use it for postoperative complications or disorders involving the ear or mastoid process when documentation is nonspecific.
Clinical signs
Clinical features vary; refer to documentation. Findings may include postoperative pain, swelling, drainage, hearing change, or other procedure-related ear symptoms, but you should code only what is documented.
When to use this code
Use H95.89 when the record clearly links the ear or mastoid disorder to a prior procedure and no more specific code is available. It is appropriate for residual or postoperative complications involving this anatomic site. If the provider names a specific complication, use that code instead.
Do not use for
Do not use this code for routine postoperative follow-up without a complication. Do not use it when a more specific ear or mastoid postprocedural complication is documented; check documentation.
Coding tip
Confirm the note states a postprocedural ear or mastoid complication and supports no better-defined code before assigning H95.89.
