What This Code Means
M25.549 is the ICD-10-CM diagnosis code for pain in joints of unspecified hand. Pain in hand joints when the specific side is not documented or when both hands are affected. M25.549 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering other joint disorders (m20-m25).
M25.549 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.
Only use when laterality is truly unspecified or undocumented.
