About coding anemia puerperal
The ICD-10-CM code for anemia puerperal is O90.81 (Anemia of the puerperium). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on O90.81.
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.
