What This Code Means
F84 is the ICD-10-CM diagnosis code for pervasive developmental disorders. F84 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering pervasive and specific developmental disorders (f80-f89).
Header codes like F84 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 F84 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
