ICD-10 Code H95.22 – Intraoperative hemorrhage and hematoma of ear and mastoid process complicating other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.22 – Intraoperative hemorrhage and hematoma of ear and mastoid process complicating other procedure
What it is
This code identifies bleeding or a hematoma affecting the ear or mastoid process that occurs during another procedure. It is used when the complication happens intraoperatively and is documented as involving the ear or mastoid area.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include visible bleeding, tissue swelling, or a noted hematoma in the operative field, with the event recorded as occurring during surgery.
When to use this code
Use H95.22 when the operative report or surgeon’s note clearly states that hemorrhage or hematoma developed in the ear or mastoid process during a procedure. Code it only when the complication is documented as intraoperative and tied to that anatomic site.
Apply the code when the complication is the focus of the record, not when bleeding is expected, minor, or unrelated to the procedure. Check documentation if the site, timing, or relationship to the procedure is unclear.
Do not use for
Do not use this code for postoperative bleeding, traumatic ear injury, or hemorrhage in another body site. If the record does not identify an intraoperative ear or mastoid complication, check documentation.
Coding tip
Confirm both the timing and the exact anatomic site in the operative note before assigning H95.22.
