ICD-10 Code H95.4 – Postprocedural hemorrhage of ear and mastoid process following a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.4 – Postprocedural hemorrhage of ear and mastoid process following a procedure
What it is
H95.4 identifies bleeding that occurs in the ear or mastoid region after a procedure. Use it when the record shows a postoperative hemorrhage or bleeding complication involving these structures.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe postoperative bleeding, oozing, hematoma, or the need for evaluation because of hemorrhage at the surgical site.
When to use this code
Use this code when a clinician documents hemorrhage as a complication of surgery or another procedure on the ear or mastoid process. It applies to postoperative bleeding linked to that procedure, not to unrelated ear bleeding. Check documentation for the exact site and timing.
Do not use for
Do not use it for ear bleeding that is not documented as postprocedural. Do not assign it when the cause is unclear or when the bleeding involves another anatomic site.
Coding tip
Confirm the operative note and postoperative complication wording before coding H95.4.
