ICD-10 Code H95 – Intraoperative and Postprocedural Complications and Disorders of Ear and Mastoid Process, Not Elsewhere Classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95 – Intraoperative and postprocedural complications and disorders of ear and mastoid process, not elsewhere classified
What it is
H95 is a category for complications or other disorders involving the ear or mastoid process that occur during or after a procedure and are not classified elsewhere. Use it when the documentation identifies a postprocedural ear or mastoid issue but gives no more specific code.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a new ear or mastoid complication after surgery, such as pain, drainage, infection, hearing change, or wound problems.
When to use this code
Use H95 when the record clearly links the ear or mastoid disorder to an operation, procedure, or postoperative state. It fits cases where the complication is documented but a more specific subcategory is not available. Check whether the note names the exact complication first.
Do not use for
Do not use H95 for routine postoperative follow-up without a complication, or for ear conditions unrelated to a procedure. If the record identifies a specific complication code, use that instead.
Coding tip
Confirm the procedure relationship and the exact complication wording before assigning H95.
