What This Code Means
M93.871 is the ICD-10-CM diagnosis code for other specified osteochondropathies, right ankle and foot. A disease affecting the bone and cartilage in the right ankle and foot area, where the specific type is documented but doesn't fit standard categories. M93.871 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering chondropathies (m91-m94).
M93.871 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.
Verify the specific osteochondropathy type is documented in the medical record before assigning this code.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for M93.871 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
