Other codes that can never be billed with M32.19
These codes carry an Excludes1 note pointing at M32.19. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M32.19 alone.
Risk adjustment
M32.19 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 94 Systemic Lupus Erythematosus and Other Specified Systemic Connective Tissue Disorders0.268 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.
