Plasmodium vivax malaria (B51)
The ICD-10 code B51 series is used to identify cases of Plasmodium vivax malaria, a specific type of malaria caused by the Plasmodium vivax parasite. These codes help differentiate whether the infection has complications or occurs without any.
The primary code, B51, covers general Plasmodium vivax malaria. More detailed coding includes B51.0, which specifies cases involving rupture of the spleen, sometimes called "Vivax malaria with rupture of spleen." This highlights a serious hematologic complication. B51.8 is used when other complications arise from the infection, while B51.9 captures uncomplicated cases. Synonyms like "malarial fever," "tertian fever," and "intermittent fever" commonly describe uncomplicated Plasmodium vivax malaria and correspond to this last code. These distinctions are crucial for clinical documentation and billing, ensuring precise identification of the presence and severity of vivax malaria.
