ICD-10 Code G97 – Intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G97 – Intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified
What it is
G97 covers nervous system complications or disorders that occur during or after a procedure and are not classified elsewhere. Use it when the documentation identifies a procedure-related neurologic problem but no more specific code applies.
Clinical signs
Clinical features vary; refer to documentation. Findings may include new neurologic deficits, altered sensation, weakness, headache, or other postoperative neurologic changes linked to the procedure.
When to use this code
Use G97 when the provider documents an intraoperative or postprocedural nervous system complication and the record does not support a more specific diagnosis. It may apply after surgery, anesthesia, or another procedure when the neurologic issue is clearly attributed to the intervention. Check documentation for the exact complication and timing.
Do not use for
Do not use G97 for routine postoperative pain, expected recovery symptoms, or neurologic conditions unrelated to a procedure. If a more specific complication code is documented, code that instead.
Coding tip
Confirm the complication is explicitly linked to the procedure and search for a more specific subcode before defaulting to G97.
