Malaria is endemic in parts of Asia, Africa, Central and South America, Oceania, and certain Caribbean islands. It is characterized by extreme exhaustion associated with paroxysms of high fever, sweating, shaking chills, and anemia. Malaria in animals is caused by other species of plasmodia. 084 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 084.0 Falciparum malaria (malignant tertian) Malaria caused by PLASMODIUM FALCIPARUM. This is the severest form of malaria and is associated with the highest levels of parasites in the blood. This disease is characterized by irregularly recurring febrile paroxysms that in extreme cases occur with acute cerebral, renal, or gastrointestinal manifestations. 084.0 is a specific code that can be used to specify a diagnosis 084.0 contains 27 index entries ICD-9-CM Diagnosis 084.1 Vivax malaria (benign tertian) Malaria caused by PLASMODIUM VIVAX. This form of malaria is less severe than MALARIA, FALCIPARUM, but there is a higher probability for relapses to occur. Febrile paroxysms often occur every other day. 084.1 is a specific code that can be used to specify a diagnosis 084.1 contains 4 index entries ICD-9-CM Diagnosis 084.2 Quartan malaria 084.2 is a specific code that can be used to specify a diagnosis 084.2 contains 6 index entries ICD-9-CM Diagnosis 084.3 Ovale malaria 084.3 is a specific code that can be used to specify a diagnosis 084.3 contains 3 index entries ICD-9-CM Diagnosis 084.4 Other malaria 084.4 is a specific code that can be used to specify a diagnosis 084.4 contains 2 index entries ICD-9-CM Diagnosis 084.5 Mixed malaria 084.5 is a specific code that can be used to specify a diagnosis 084.5 contains 1 index entry ICD-9-CM Diagnosis 084.6 Malaria unspecified A protozoan disease caused in humans by four species of the genus PLASMODIUM (P. falciparum (MALARIA, FALCIPARUM); P. vivax (MALARIA, VIVAX); P. ovale, and P. malariae) and transmitted by the bite of an infected female mosquito of the genus Anopheles. Malaria is endemic in parts of Asia, Africa, Central and South America, Oceania, and certain Caribbean islands. It is characterized by extreme exhaustion associated with paroxysms of high fever, sweating, shaking chills, and anemia. Malaria in animals is caused by other species of plasmodia. 084.6 is a specific code that can be used to specify a diagnosis 084.6 contains 43 index entries ICD-9-CM Diagnosis 084.7 Induced malaria 084.7 is a specific code that can be used to specify a diagnosis 084.7 contains 2 index entries ICD-9-CM Diagnosis 084.8 Blackwater fever A complication of MALARIA, FALCIPARUM characterized by the passage of dark red to black urine. 084.8 is a specific code that can be used to specify a diagnosis 084.8 contains 22 index entries ICD-9-CM Diagnosis 084.9 Other pernicious complications of malaria A condition characterized by somnolence or coma in the presence of an acute infection with PLASMODIUM FALCIPARUM (and rarely other Plasmodium species). Initial clinical manifestations include HEADACHES, SEIZURES, and alterations of mentation followed by a rapid progression to COMA. Pathologic features include cerebral capillaries filled with parasitized erythrocytes and multiple small foci of cortical and subcortical necrosis. 084.9 is a specific code that can be used to specify a diagnosis 084.9 contains 16 index entries
