Other protozoal intestinal diseases (A07)
The ICD-10 codes under A07 cover various protozoal intestinal diseases, representing infections caused by different protozoa affecting the intestines. These codes are used to classify specific parasitic intestinal infections like balantidiasis, giardiasis, cryptosporidiosis, isosporiasis, cyclosporiasis, and other identified protozoal infections.
This set of codes helps healthcare professionals and medical coders accurately identify infections caused by protozoa such as Balantidium coli (balantidiasis, A07.0), Giardia lamblia (giardiasis, A07.1), Cryptosporidium species (cryptosporidiosis, A07.2), Cystoisospora belli (isosporiasis, A07.3), and Cyclospora (cyclosporiasis, A07.4). The category also includes less common protozoal infections under A07.8 and cases where the specific protozoal cause is not specified (A07.9). Using these ICD-10 codes ensures precise documentation of infections presenting as intestinal inflammation, colitis, or diarrhea caused by protozoan parasites. These codes are essential for accurate diagnosis, treatment planning, and epidemiological tracking of protozoal intestinal diseases.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
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.
