B77.9 is a billable ICD-10 code used to specify a medical diagnosis of ascariasis, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like B77.9 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Ascariasis caused by adult Ascaris
- Infection by Ascaridia
- Infection by Ascaridia dissimilis
- Infection by Ascaridia galli
- Infection by Ascaris lumbricoides
- Infection by Ascaris suum
- Migratory ascariasis
- Ascariasis-. infection by nematodes of the genus ascaris. ingestion of infective eggs causes diarrhea and pneumonitis. its distribution is more prevalent in areas of poor sanitation and where human feces are used for fertilizer.
- Ascaris-. a genus of nematodes of the superfamily ascaridoidea whose species usually inhabit the intestine.
- Ascariasis-. an infection that is caused by the roundworm ascaris lumbricoides, many cases of which remain asymptomatic. during the transient larval migratory phase, shortness of breath, fever, and eosinophilia can occur. depending on the intestinal worm burden, a spectrum of gastrointestinal tract symptoms can occur.
- Baylisascariasis|Raccoon Roundworm Infection-. an infection that is caused by the raccoon nematode baylisascaris procyonis, which is transmitted by the ingestion of embryonated eggs in contaminated soil; symptoms depend on larval migration sites (visceral organs, eye, or brain) provoking severe inflammatory responses.

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.
