Other codes that can never be billed with E70.330
These codes carry an Excludes1 note pointing at E70.330. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E70.330 alone.
Risk adjustment
E70.330 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

E70.330 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
