What This Code Means
M12.822 is the ICD-10-CM diagnosis code for other specific arthropathies, not elsewhere classified, left elbow. A specific type of joint disease affecting the left elbow that doesn't fit into other standard categories. M12.822 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering inflammatory polyarthropathies (m05-m14).
M12.822 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 left elbow is documented; use M12.821 for right elbow.
