    (A00–B99)

B74 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of filariasis. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Filariasis

Non-specific codes like B74 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for filariasis:

  • Use B74.0 for Filariasis due to Wuchereria bancrofti - BILLABLE CODE

  • Use B74.1 for Filariasis due to Brugia malayi - BILLABLE CODE

  • Use B74.2 for Filariasis due to Brugia timori - BILLABLE CODE

  • Use B74.3 for Loiasis - BILLABLE CODE

  • Use B74.4 for Mansonelliasis - BILLABLE CODE

  • Use B74.8 for Other filariases - BILLABLE CODE

  • Use B74.9 for Filariasis, unspecified - BILLABLE CODE

Clinical Information

  • Elephantiasis, Filarial

    parasitic infestation of the human lymphatic system by wuchereria bancrofti or brugia malayi. it is also called lymphatic filariasis.
  • Filariasis

    infections with nematodes of the superfamily filarioidea. the presence of living worms in the body is mainly asymptomatic but the death of adult worms leads to granulomatous inflammation and permanent fibrosis. organisms of the genus elaeophora infect wild elk and domestic sheep causing ischemic necrosis of the brain, blindness, and dermatosis of the face.
  • Loiasis

    a parasitic infection caused by the nematode loa loa. the vector in the transmission of this infection is the horsefly (tabanus) or the deerfly or mango fly (chrysops). the larvae may be seen just beneath the skin or passing through the conjunctiva. eye lesions are not uncommon. the disease is generally mild and painless.
  • Filarioidea

    a superfamily of nematodes of the order spirurida. members possess a filiform body and a mouth surrounded by papillae.
  • Filariasis

    infection by filarial worms.
  • Lymphatic Filariasis|Elephantiasis

    a clinical disorder that is caused by obstruction of the lymphatic system years after filarial infection. it is characterized by painful and profound lymphedema, resulting in significant swelling (elephantiasis) of extremities and genitals.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • onchocerciasis B73
  • tropical pulmonary eosinophilia NOS J82.89

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.
