Other codes that can never be billed with R57.9
These codes carry an Excludes1 note pointing at R57.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R57.9 alone.
Risk adjustment
R57.9 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 213 Cardio-Respiratory Failure and Shock0.370 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.
