What This Code Means
V21 is the ICD-10-CM diagnosis code for motorcycle rider injured in collision with pedal cycle. V21 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering motorcycle rider injured in transport accident (v20-v29).
Header codes like V21 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 V21 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
