Plasmodium vivax malaria with other complications

This code signifies a diagnosis of malaria caused by the Plasmodium vivax parasite, where the patient is experiencing additional complications beyond the typical febrile illness. These complications can affect various organ systems and indicate a more severe disease presentation.

Use this code when documentation explicitly states Plasmodium vivax malaria and describes specific complications such as severe anemia, splenic rupture, acute kidney injury, or other organ involvement. The physician's notes must clearly link the complication to the P. vivax infection.

• Always ensure the documentation specifies Plasmodium vivax as the causative agent; do not use for other Plasmodium species.
• Code the specific complication(s) separately in addition to this malaria code, following ICD-10-CM sequencing guidelines.
• Distinguish from B51.0 (malaria with cerebral complications) and B51.9 (malaria without complications).
