Their own Excludes1 notes name this code, so the conflict is not listed above.
Risk adjustment
G37.0 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 198 Multiple Sclerosis0.647 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.
Medicare coverage
G37.0 is named in 19 Medicare coverage policies: 19 listing it as supporting medical necessity. Which one applies depends on your Medicare contractor.
