2026 ICD-10-CM Diagnosis Code H95.51 – Postprocedural hematoma of ear and mastoid process following a procedure on the ear and mastoid process
What it is
H95.51 identifies a hematoma that develops after a procedure on the ear or mastoid process. It means blood has collected in the surgical area after an ear-related intervention.
Clinical signs
Look for postoperative swelling, localized bruising, tenderness, or a firm mass near the ear or mastoid region. Clinical features vary; refer to documentation for confirmation of a postprocedural hematoma.
When to use this code
Use this code when the record clearly states a hematoma occurred after surgery or another procedure on the ear or mastoid process. It applies when the provider documents the complication as postprocedural and links it to the prior ear procedure. Check documentation if laterality or exact procedure details are needed.
Do not use for
Do not use this code for routine postoperative bruising without a documented hematoma. Do not use it for ear bleeding or swelling unrelated to a prior procedure; check documentation.
Coding tip
Code the complication only when the provider documents it as postprocedural and tied to the ear or mastoid procedure.
