Other malaria, not elsewhere classified

This code represents malaria infections that are not specifically identified as Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, or mixed malaria. It encompasses other less common Plasmodium species or atypical presentations not classifiable to a more specific malaria code.

Use this code when diagnostic testing confirms a malaria infection, but the specific Plasmodium species is identified as something other than the four common types (e.g., Plasmodium knowlesi) or when the documentation explicitly states "other malaria" without further specification that would allow for a more precise code. Documentation should clearly indicate a confirmed malaria diagnosis and the absence of a more specific species identification.

• Do not use this code for unspecified malaria; refer to B54 for that scenario.
• Ensure the medical record explicitly rules out P. falciparum, P. vivax, P. ovale, and P. malariae before assigning this code.
• Always sequence the malaria code first, followed by any associated manifestations or complications.
