2026 ICD-10-CM Diagnosis Code H95.88 – Other intraoperative complications and disorders of the ear and mastoid process, not elsewhere classified
What it is
This code reports an intraoperative complication or disorder affecting the ear or mastoid process that is not described by a more specific ICD-10-CM code. Use it when the event occurs during surgery and the documentation supports an ear or mastoid complication.
Clinical signs
Clinical features vary; refer to documentation. You may see operative notes describing unexpected injury, disruption, or other complication involving the ear or mastoid region during a procedure.
When to use this code
Use H95.88 when the surgeon documents an intraoperative complication involving the ear or mastoid process and no more specific code applies. It is appropriate for coding the complication itself, not the original reason for surgery. Check documentation for laterality, if recorded, and for any additional procedure-related codes.
Do not use for
Do not use this code for postoperative complications, routine surgical findings, or conditions unrelated to surgery. If the record identifies a more specific ear or mastoid complication, code that instead.
Coding tip
Code only what the operative report clearly states, and query for specificity if the complication type or site is unclear.
