What This Code Means
M00.2 is the ICD-10-CM diagnosis code for other streptococcal arthritis and polyarthritis. M00.2 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering infectious arthropathies (m00-m02).
Header codes like M00.2 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 M00.2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
