ICD-10 Code G97.6 – Postprocedural hematoma and seroma of a nervous system organ or structure following a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G97.6 – Postprocedural hematoma and seroma of a nervous system organ or structure following a procedure
What it is
This code identifies a hematoma or seroma that develops after a procedure involving a nervous system organ or structure. Use it when the complication is documented as occurring after surgery or another procedure.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include swelling, pain, wound fullness, or neurologic change related to a postoperative collection at the operative site.
When to use this code
Use G97.6 when the provider documents a postprocedural hematoma or seroma involving the brain, spinal cord, or related nervous system structure. It applies when the complication is clearly linked to the procedure and not to trauma or infection. Check documentation if the site or cause is unclear.
Do not use for
Do not use this code for traumatic hematomas, abscesses, or routine postoperative pain without a documented hematoma or seroma. Check documentation if the collection is in a non-neurologic surgical site.
Coding tip
Assign the code only when the record states a postprocedural hematoma or seroma; otherwise, query for clarification.
