What This Code Means
M50.122 is the ICD-10-CM diagnosis code for cervical disc disorder at c5-c6 level with radiculopathy. A herniated or damaged disc between the 5th and 6th neck vertebrae that is pressing on a nerve root, causing pain, numbness, or weakness in the arm. M50.122 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering other dorsopathies (m50-m54).
M50.122 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.
Confirm documentation specifies C5-C6 level and radiculopathy diagnosis.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for M50.122 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
