About ICD-9-CM 084.0
084.0 is an ICD-9-CM diagnosis code for falciparum malaria [malignant tertian]. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as B50.8 (Other severe and complicated Plasmodium falciparum malaria) and B50.9 (Plasmodium falciparum malaria, unspecified). All of these are approximate matches, so review the record to pick the right one.
