O99.03 — Anemia complicating the puerperium
O99.03 is a billable, specific ICD-10-CM code for anemia complicating the puerperium. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- postpartum anemia not pre-existing prior to delivery (O90.81)
Other codes that can never be billed with O99.03
These codes carry an Excludes1 note pointing at O99.03. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O99.03 alone.
- O90.81Anemia of the puerperium
Risk adjustment
O99.03 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.
How O99.03 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to O99.03.
