The V24 → V28 RAF Shift
Same documented member, two models.
When CMS moved from the HCC V24 model to V28, the documentation didn't change — but the way it scores did. This illustrative infographic walks through how one hypothetical member's RAF can land differently under each version: categories get renumbered, coefficients get re-estimated, some conditions are no longer payable, and a transition blend weights the two scores together.
The numbers here are invented for teaching. The point isn't the specific values, it's the shape of what changes between versions.
The bigger takeaway sits in the footer: accuracy over intensity. V28 changes which accurate documentation pays, and how much — not the standard that the score has to reflect the real, documented patient.
Side-by-side and a worked example in the full HCC V28 guide.
