These conditions cannot occur together. Billing both on the same encounter is a denial.

Other codes that can never be billed with E84.11
These codes carry an Excludes1 note pointing at E84.11. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E84.11 alone.
Risk adjustment
E84.11 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 277 Cystic Fibrosis0.998 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.
