About coding ovale malaria
The ICD-10-CM code for ovale malaria is B53.0 (Plasmodium ovale malaria).
Within B53 (other specified malaria), B53.0 is specifically for Plasmodium ovale malaria. Related codes cover malaria due to simian plasmodia (B53.1) and other malaria, not elsewhere classified (B53.8).
Don't report B53.0 together with the conditions in its Excludes1 note: Plasmodium ovale with Plasmodium falciparum (B50.-), Plasmodium ovale with Plasmodium malariae (B52.-) and Plasmodium ovale with Plasmodium vivax (B51.-).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
Don't confuse with (Excludes1 for B53.0)
