ICD-10 Code H95.54 – Postprocedural seroma of ear and mastoid process following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.54 – Postprocedural seroma of ear and mastoid process following other procedure
What it is
H95.54 identifies a seroma that develops after a procedure involving the ear or mastoid process. It refers to a postoperative fluid collection, not an infection or abscess.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe localized swelling, a soft fluid-filled mass, or postoperative fullness near the surgical site, with or without discomfort.
When to use this code
Use this code when the provider documents a seroma specifically as a postprocedural complication of ear or mastoid surgery. It is appropriate when the record links the fluid collection to the prior procedure and names the site clearly. Check documentation if the complication type or anatomic location is unclear.
Do not use for
Do not use this code for routine postoperative drainage without a documented seroma, or for infection, hematoma, or abscess. If the record does not specify a postprocedural seroma, check documentation.
Coding tip
Confirm both the postoperative nature and the ear or mastoid site in the provider note before assigning H95.54.
