What This Code Means
M87.17 is the ICD-10-CM diagnosis code for osteonecrosis due to drugs, ankle, foot and toes. M87.17 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).
Header codes like M87.17 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for M87.17 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
