ICD-10 Code G97.51 – Postprocedural hemorrhage of a nervous system organ or structure following a nervous system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G97.51 – Postprocedural hemorrhage of a nervous system organ or structure following a nervous system procedure
What it is
This code identifies bleeding that occurs after a procedure involving a nervous system organ or structure. Use it when the hemorrhage is documented as a postoperative or postprocedural complication.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include new neurologic symptoms, evidence of bleeding on imaging, or a noted postoperative hemorrhage at the procedure site.
When to use this code
Use G97.51 when the record states that hemorrhage followed a nervous system procedure and the provider links the bleeding to that procedure. It is appropriate for postprocedure complications involving the brain, spinal cord, or related structures. Code only when the documentation clearly identifies the hemorrhage as postoperative.
Do not use for
Do not use this code for hemorrhage unrelated to a procedure or for bleeding after non-nervous-system procedures. If the documentation does not specify a postoperative nervous system hemorrhage, check documentation.
Coding tip
Confirm both the procedure site and the complication wording before assigning G97.51.
