Is M12.841 an HCC code?
No. M12.841 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
M12.841 is the ICD-10-CM diagnosis code for other specific arthropathies, not elsewhere classified, right hand. A joint condition affecting the right hand that doesn't fit into other specific arthropathy categories. M12.841 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).
M12.841 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.
Verify that 'hand' refers to the wrist/hand area and not fingers, which may require different coding.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for M12.841 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify that 'hand' refers to the wrist/hand area and not fingers, which may require different coding
- •Ensure right hand is clearly documented; use M12.849 if side is unspecified
