What This Code Means

G97.81 is the ICD-10-CM diagnosis code for other intraoperative complications of nervous system. Complications of the nervous system that occur during a surgical procedure, such as nerve damage or bleeding during brain or spinal surgery. G97.81 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering other disorders of the nervous system (g89-g99).

G97.81 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This code requires documentation of the specific intraoperative complication; review operative notes for details.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G97.81 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
