Code Classification

  • Certain infectious and parasitic diseases
    (A00–B99)
    • Intestinal infectious diseases
      (A00-A09)
      • Amebiasis
        (A06)

A06.9 is a billable diagnosis code used to specify a medical diagnosis of amebiasis, 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 A06.9 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.

Clinical Information

  • Amebiasis

    infection with any of various amebae. it is an asymptomatic carrier state in most individuals, but diseases ranging from chronic, mild diarrhea to fulminant dysentery may occur.

  • Dysentery, Amebic

    dysentery caused by intestinal amebic infection, chiefly with entamoeba histolytica. this condition may be associated with amebic infection of the liver and other distant sites.

  • Liver Abscess, Amebic

    single or multiple areas of pus due to infection by any ameboid protozoa (amebiasis). a common form is caused by the ingestion of entamoeba histolytica.

  • Amebiasis

    a parasitic infectious disorder caused by amoebas. the parasite may cause colitis which is manifested with bloody diarrhea, abdominal pain, nausea and fever. in rare cases it may spread to the liver, brain and lungs.

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.
