Hemolysis following incomplete spontaneous abortion

Other codes that can never be billed with O03.1

These codes carry an Excludes1 note pointing at O03.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O03.1 alone.

Risk adjustment

O03.1 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

O03.1 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
