About ICD-9-CM 084.5
084.5 is an ICD-9-CM diagnosis code for mixed malaria. 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 3 ICD-10-CM codes, such as B50.9 (Plasmodium falciparum malaria, unspecified), B51.9 (Plasmodium vivax malaria without complication) and B52.9 (Plasmodium malariae malaria without complication). All of these are approximate matches, so review the record to pick the right one.
