ICD-10 Code G97.8 – Other intraoperative and postprocedural complications and disorders of nervous system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G97.8 – Other intraoperative and postprocedural complications and disorders of nervous system
What it is
G97.8 identifies nervous system complications or disorders that occur during or after a procedure and are not classified elsewhere. Use it when the documentation clearly links the neurologic problem to the operation or postoperative period.
Clinical signs
Clinical features vary; refer to documentation. Findings may include new neurologic deficits, altered sensation, weakness, pain, or other postoperative nerve-related complications described by the treating clinician.
When to use this code
Use this code when the record states a nervous system complication is intraoperative or postoperative and no more specific code applies. It may fit after surgery if the provider documents a related neurologic disorder, such as nerve injury or other complication. Check documentation for the exact relationship and specificity.
Do not use for
Do not use G97.8 for routine postoperative pain, expected recovery findings, or neurologic conditions that are unrelated to the procedure. If the complication has a more specific code, use that instead.
Coding tip
Look for explicit provider documentation tying the neurologic problem to the procedure, because the cause and timing determine correct code selection.
