Plasmodium vivax malaria without complication

This code signifies a confirmed diagnosis of malaria caused specifically by the parasite Plasmodium vivax, where the patient is not experiencing any severe manifestations or complications typically associated with malaria, such as cerebral malaria, severe anemia, or renal failure. It represents an uncomplicated case of P. vivax infection.

Use this code when diagnostic testing, such as a blood smear or rapid diagnostic test, confirms the presence of Plasmodium vivax and the physician's documentation explicitly states that the malaria is uncomplicated. This code is appropriate for patients presenting with typical malaria symptoms (fever, chills, headache) without evidence of organ dysfunction or severe disease.

• Ensure documentation clearly specifies Plasmodium vivax as the causative agent.
• Do not use this code if any complications of malaria are documented; instead, select a more specific code from category B51 that includes the complication.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
