084.4
ICD-9-CMThis code signifies a diagnosis of malaria that is not specifically identified as Plasmodium falciparum, vivax, malariae, or ovale. It encompasses less common Plasmodium species infections or cases where the specific species is undetermined but malaria is confirmed.
Apply this code when documentation confirms a malaria infection, but the specific Plasmodium species is not documented or is identified as a species other than P. falciparum, P. vivax, P. malariae, or P. ovale. This is appropriate for diagnoses such as P. knowlesi malaria or "unspecified malaria."
