O90.81 — Anemia of the puerperium
O90.81 is a billable, specific ICD-10-CM code for anemia of 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.
- pre-existing anemia complicating the puerperium (O99.03)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Postpartum anemia NOS
Other codes that can never be billed with O90.81
These codes carry an Excludes1 note pointing at O90.81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O90.81 alone.
Risk adjustment
O90.81 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 O90.81 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 O90.81.
- Anemia›postpartum
- Puerperal, puerperium›anemia
