Other protozoal intestinal diseases (A07)

Browse all the diagnosis codes used for other protozoal intestinal diseases (a07). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Balantidiasis - Infection by parasites of the genus BALANTIDIUM. The presence of Balantidium in the LARGE INTESTINE leads to DIARRHEA; DYSENTERY; and occasionally ULCER.

Coccidia - A subclass of protozoans commonly parasitic in the epithelial cells of the intestinal tract but also found in the liver and other organs. Its organisms are found in both vertebrates and higher invertebrates and comprise two orders: EIMERIIDA and EUCOCCIDIIDA.

Coccidiosis - Protozoan infection found in animals and man. It is caused by several different genera of COCCIDIA.

Cryptosporidiosis - Intestinal infection with organisms of the genus CRYPTOSPORIDIUM. It occurs in both animals and humans. Symptoms include severe DIARRHEA.

Cyclospora - A genus of coccidian parasites in the family EIMERIIDAE. Cyclospora cayetanensis is pathogenic in humans, probably transmitted via the fecal-oral route, and causes nausea and diarrhea.

Cyclosporiasis - Infection with parasitic protozoa of the genus CYCLOSPORA. It is distributed globally and causes a diarrheal illness. Transmission is waterborne.

Giardiasis - An infection of the SMALL INTESTINE caused by the flagellated protozoan GIARDIA. It is spread via contaminated food and water and by direct person-to-person contact.

Isospora - A genus of protozoan parasites found in the intestines of birds, amphibians, reptiles, and mammals, including man. The oocysts produce two sporocysts, each with four sporozoites. Many species are parasitic in wild and domestic animals.

Isosporiasis - Infection with parasitic protozoa of the genus ISOSPORA, producing intestinal disease. It is caused by ingestion of oocysts and can produce tissue cysts.
