What This Code Means
M19.031 is the ICD-10-CM diagnosis code for primary osteoarthritis, right wrist. Wear and tear arthritis of the right wrist joint, occurring without a prior injury or underlying condition. M19.031 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering osteoarthritis (m15-m19).
M19.031 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.
