O43
O43 — Placental disorders
Non-billable headerICD-10-CM
O43 is a non-billable header ICD-10-CM code for placental disorders. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Other codes that can never be billed with O43
These codes carry an Excludes1 note pointing at O43. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O43 alone.
Risk adjustment
O43 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 to one of these instead O43
5 child codes. Green means billable.
