What This Code Means

M84.852 is the ICD-10-CM diagnosis code for other disorders of continuity of bone, left pelvic region and thigh. A bone disorder affecting the continuity or structural integrity of bone in the left hip, pelvis, or thigh area, not classified as a fracture or other specific condition. M84.852 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering disorders of bone density and structure (m80-m85).

M84.852 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 laterality is documented as left; if not specified, use M84.859 instead.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for M84.852 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips
