2025 ICD-10-CM Diagnosis Code B54

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Clinical Information

• Blackwater Fever

  a complication of malaria, falciparum characterized by the passage of dark red to black urine.

• Malaria

  a protozoan disease caused in humans by four species of the plasmodium genus: plasmodium falciparum; plasmodium vivax; plasmodium ovale; and plasmodium 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.

• Malaria Vaccines

  vaccines made from antigens arising from any of the four strains of plasmodium which cause malaria in humans, or from p. berghei which causes malaria in rodents.

• Malaria, Avian

  any of a group of infections of fowl caused by protozoa of the genera plasmodium, leucocytozoon, and haemoproteus. the life cycles of these parasites and the disease produced bears strong resemblance to those observed in human malaria.

• Malaria, Cerebral

  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. (from adams et al., principles of neurology, 6th ed, p136)

• Malaria, Falciparum

  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.

• Malaria, Vivax

  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.

• Plasmodium

  a genus of protozoa that comprise the malaria parasites of mammals. four species infect humans (although occasional infections with primate malarias may occur). these are plasmodium falciparum; plasmodium malariae; plasmodium ovale, and plasmodium vivax. species causing infection in vertebrates other than man include: plasmodium berghei; plasmodium chabaudi; p. vinckei, and plasmodium yoelii in rodents; p. brasilianum, plasmodium cynomolgi; and plasmodium knowlesi in monkeys; and plasmodium gallinaceum in chickens.

• Plasmodium falciparum

  a species of protozoa that is the causal agent of falciparum malaria (malaria, falciparum). it is most prevalent in the tropics and subtropics.

• Antimalarial Agent|Anti-Malarial Agent|Anti-Malarial Drug|Antimalarial Drugs|Antimalarials

  agents used to treat malaria, and are usually classified based on action against plasmodia at different stages in their life cycle in the human.

• Blackwater Fever|Malarial Hemoglobinuria

  a complication of malaria resulting from hemolysis.

• CDISC Malaria Therapeutic Area User Guide Version 1.0|Malaria Therapeutic Area User Guide v1.0

  the 1.0 version of the cdisc malaria therapeutic area user guide.

• CDISC SDTM Malaria Findings About Test Code Terminology|MRFATSCD|Malaria Findings About Test Code|SDTM-MRFATSCD

  terminology associated with the malaria findings about test code codelist of the clinical data interchange standards consortium (cdisc) study data tabulation model (sdtm).

• CDISC SDTM Malaria Findings About Test Name Terminology|MRFATS|Malaria Findings About Test Name|SDTM-MRFATS

  terminology associated with the malaria findings about test name codelist of the clinical data interchange standards consortium (cdisc) study data tabulation model (sdtm).

• Cerebral Malaria

  a sequestration of plasmodium falciparum in the brain, which can cause coma and/or seizures.

• Falciparum Malaria

  malaria resulting from infection by plasmodium falciparum.

• Malaria

  a protozoan infection caused by the genus plasmodium. there are four species of plasmodium that can infect humans: plasmodium falciparum, vivax, ovale, and malariae. it is transmitted to humans by infected mosquitoes. signs and symptoms include paroxysmal high fever, sweating, chills, and anemia.

• Nephrotic Syndrome - Malaria Associated|Malaria Associated Nephrotic Syndrome

  nephrotic syndrome associated with malaria.

• Plasmodium malariae|PLASMODIUM MALARIAE

  a protozoan parasite in the family plasmodiidae. p. malariae causes quartan malaria, a milder form of malaria than that caused by p. falciparum or p. vivax.

• Plasmodium Measurement|Malaria|PLSMDM|Plasmodium|Plasmodium

  the determination of the amount of plasmodium present in a sample.

• Quartan Malaria

  malaria resulting from infection by plasmodium malariae.

• Severe Malaria|Complicated Malaria

  acute malaria with signs of organ dysfunction, severe anemia (hemoglobin less than 5 g/dl or hematocrit less than 15%) and/or hyperparasitemia (greater than 5% of red blood cells infected).

• Vivax Malaria

  malaria resulting from infection by plasmodium vivax.

MS-DRG Mapping for ICD-10-CM Code B54

Diagnosis-Related Groups (DRGs) are used to classify hospital cases for billing and healthcare management. They help standardize how hospitals and other providers are reimbursed for inpatient care. Patients are grouped based on their principal diagnosis into broader categories called Major Diagnostic Categories (MDCs).

Once assigned to a DRG, the hospital receives a set payment for the patient’s care, regardless of the actual services provided. This fixed rate is intended to cover the typical cost of treating patients within that group. The payment amount depends on the DRG's relative weight, which reflects the expected complexity and cost of care based on the severity of the patient’s condition.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V42.0 applicable from 10/01/2024 through 09/30/2025.

Convert B54 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Patient Education

Malaria

Malaria is a serious disease caused by a parasite. You get it when an infected mosquito bites you. Malaria is a major cause of death worldwide, but it is almost wiped out in the United States. The disease is mostly a problem in developing countries with warm climates. If you travel to these countries, you are at risk. There are four different types of malaria caused by four related parasites. The most deadly type occurs in Africa south of the Sahara Desert.

Malaria symptoms include chills, flu-like symptoms, fever, vomiting, diarrhea, and jaundice. A blood test can diagnose it. It can be life-threatening. However, you can treat malaria with drugs. The type of drug depends on which kind of malaria you have and where you were infected.

Malaria can be prevented. When traveling to areas where malaria is found:

• See your doctor for medicines that protect you
• Wear insect repellent with DEET
• Cover up
• Sleep under mosquito netting
