- HCC 92 Bone/Joint/Muscle/Severe Soft Tissue Infections/Necrosis0.479 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.
