About coding postpartum anemia
The ICD-10-CM code for postpartum anemia is O90.81 (Anemia of the puerperium).
Within O90.8 (other complications of the puerperium, not elsewhere classified), O90.81 is specifically for anemia of the puerperium. Related codes cover other complications of the puerperium, not elsewhere classified (O90.89).
Don't report O90.81 together with the conditions in its Excludes1 note: pre-existing anemia complicating the puerperium (O99.03).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for O90.81)
- pre-existing anemia complicating the puerperium (O99.03)
