Other codes that can never be billed with E22.8

These codes carry an Excludes1 note pointing at E22.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E22.8 alone.

Risk adjustment

E22.8 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.

Medicare coverage

E22.8 is named in 11 Medicare coverage policies — 11 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
