What This Code Means
R29.7 is the ICD-10-CM diagnosis code for national institutes of health stroke scale (nihss) score. R29.7 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering symptoms and signs involving the nervous and musculoskeletal systems (r25-r29).
Header codes like R29.7 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 R29.7 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
