What This Code Means

M25.559 is the ICD-10-CM diagnosis code for pain in unspecified hip. Pain in the hip joint when the specific side is not documented or is bilateral. M25.559 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).

M25.559 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.

Use only when laterality cannot be determined from the medical record.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for M25.559 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
