What This Code Means
G89.0 is the ICD-10-CM diagnosis code for central pain syndrome. Chronic pain originating from the central nervous system (brain or spinal cord) rather than from an injury or disease at a specific body location. G89.0 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).
G89.0 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.
Document whether the central pain syndrome is acute or chronic; this code specifically indicates the chronic form.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G89.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document whether the central pain syndrome is acute or chronic; this code specifically indicates the chronic form
- •Verify the pain is truly centrally mediated and not secondary to another documented condition
