ICD-10 Code G97.63 – Postprocedural seroma of a nervous system organ or structure following a nervous system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G97.63 – Postprocedural seroma of a nervous system organ or structure following a nervous system procedure
What it is
This code identifies a seroma, or localized fluid collection, that develops after a procedure involving a nervous system organ or structure. It reflects a postoperative complication rather than the original neurologic condition.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include a postoperative swelling or fluid collection at the surgical site, sometimes with discomfort, pressure, or wound drainage.
When to use this code
Use G97.63 when the provider documents a seroma specifically linked to a prior nervous system procedure, such as surgery involving the brain, spinal cord, or related structures. Code the complication only when the relationship to the procedure is stated or clearly supported in the record.
If the note describes a different postoperative issue, such as infection, hematoma, or CSF leak, do not assign this code. Check documentation when the complication type is unclear.
Do not use for
Do not use this code for a generic postoperative fluid collection without documentation that it is a seroma after a nervous system procedure. It also should not be used for non-neurologic surgical sites.
Coding tip
Link the seroma to the specific nervous system procedure in the record before assigning G97.63.
