ICD-10 Code H95.52 – Postprocedural hematoma of ear and mastoid process following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.52 – Postprocedural hematoma of ear and mastoid process following other procedure
What it is
H95.52 identifies a hematoma involving the ear or mastoid process that develops after a procedure. Use it when the chart documents postoperative bleeding or a localized blood collection in this area.
Clinical signs
Typical findings include swelling, bruising, pain, or a palpable mass at the surgical site. Clinical features vary; refer to documentation, especially for notes describing postoperative bleeding or fluid collection.
When to use this code
Use this code when the provider documents a postprocedural hematoma of the ear or mastoid process after a qualifying procedure. It fits situations where the complication is clearly linked to the prior intervention and not to trauma or a spontaneous lesion.
Code it from operative, progress, or discharge documentation that names the complication. If the record only says “postoperative swelling” without hematoma, check documentation before assigning H95.52.
Do not use for
Do not use this code for traumatic ear injuries, uncomplicated postoperative swelling, or hematomas elsewhere on the body. If the source or site is unclear, check documentation.
Coding tip
Confirm both the postoperative relationship and the ear or mastoid site before coding H95.52.
