Code Classification

  • Certain infectious and parasitic diseases
    (A00–B99)
    • Protozoal diseases
      (B50-B64)
      • African trypanosomiasis
        (B56)

B56.9 is a billable diagnosis code used to specify a medical diagnosis of african trypanosomiasis, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like B56.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

  • Infection by Trypanosoma brucei brucei
  • Infection by Trypanosoma suis

Clinical Classification

Clinical Information

  • Chagas Cardiomyopathy

    a disease of the cardiac muscle developed subsequent to the initial protozoan infection by trypanosoma cruzi. after infection, less than 10% develop acute illness such as myocarditis (mostly in children). the disease then enters a latent phase without clinical symptoms until about 20 years later. myocardial symptoms of advanced chagas disease include conduction defects (heart block) and cardiomegaly.
  • Chagas Disease

    infection with the protozoan parasite trypanosoma cruzi, a form of trypanosomiasis endemic in central and south america. it is named after the brazilian physician carlos chagas, who discovered the parasite. infection by the parasite (positive serologic result only) is distinguished from the clinical manifestations that develop years later, such as destruction of parasympathetic ganglia; chagas cardiomyopathy; and dysfunction of the esophagus or colon.
  • Trypanosomiasis

    infection with protozoa of the genus trypanosoma.
  • Trypanosomiasis, African

    a disease endemic among people and animals in central africa. it is caused by various species of trypanosomes, particularly t. gambiense and t. rhodesiense. its second host is the tsetse fly. involvement of the central nervous system produces "african sleeping sickness." nagana is a rapidly fatal trypanosomiasis of horses and other animals.
  • Trypanosomiasis, Bovine

    infection in cattle caused by various species of trypanosomes.
  • Trypanosoma

    a genus of flagellate protozoans found in the blood and lymph of vertebrates and invertebrates, both hosts being required to complete the life cycle.
  • Tsetse Flies

    bloodsucking flies of the genus glossina, found primarily in equatorial africa. several species are intermediate hosts of trypanosomes.

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Convert B56.9 to ICD-9-CM

  • ICD-9-CM Code: 086.5 - African trypanosoma NOS
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
  • ICD-9-CM Code: 086.9 - Trypanosomiasis NOS
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Parasitic Diseases

Parasites are living things that use other living things - like your body - for food and a place to live. You can get them from contaminated food or water, a bug bite, or sexual contact. Some parasitic diseases are easily treated and some are not.

Parasites range in size from tiny, one-celled organisms called protozoa to worms that can be seen with the naked eye. Some parasitic diseases occur in the United States. Contaminated water supplies can lead to Giardia infections. Cats can transmit toxoplasmosis, which is dangerous for pregnant women. Others, like malaria, are common in other parts of the world.

If you are traveling, it's important to drink only water you know is safe. Prevention is especially important. There are no vaccines for parasitic diseases. Some medicines are available to treat parasitic infections.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
