Risk adjustment
F22 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:
- HCC 152 Psychosis, Except Schizophrenia0.484 RAF
- HCC 152 Psychosis, Except Schizophrenia0.484 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score. Look up the whole chart to see which of its HCCs the hierarchy would zero.
