What This Code Means
M89.125 is the ICD-10-CM diagnosis code for complete physeal arrest, right distal humerus. A condition where the growth plate in the right upper arm bone (near the elbow) has completely stopped growing, preventing further bone lengthening in that area. M89.125 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering other osteopathies (m86-m90).
M89.125 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Confirm documentation explicitly states 'complete' physeal arrest at the distal humerus.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for M89.125 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
