What the Online Code Book Does

What the online code book doesA tabbed ICD-10-CM code book on the left connects to an HCC mapping panel showing the HCC category, RAF value, MEAT support, and the ICD-10-CM source label.Tabbed ICD-10-CMHCC mapping & RAFE11.65I50.22J44.9N18.32Notes & highlights savedE11.65HCC 38RAF weightMEAT supportMEATSource · ICD-10-CM 2026

The online ICD-10-CM code book keeps the full tabbed index next to its HCC mapping, RAF values, MEAT support, and source labels, so coders can move from a diagnosis to its risk-adjustment context without leaving the page. Notes and highlights stay attached to each code for the next pass.
