Other codes that can never be billed with O45.01

These codes carry an Excludes1 note pointing at O45.01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O45.01 alone.

O67Labor and delivery complicated by intrapartum hemorrhage, not elsewhere classified
O46Antepartum hemorrhage, not elsewhere classified
O99.1Other diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism complicating pregnancy, childbirth and the puerperium

Risk adjustment

O45.01 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.

Code history

O45.01 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
