Major groups of parasites include protozoans (organisms having only one cell) and parasitic worms (helminths). Of these, protozoans, including cryptosporidium, microsporidia, and isospora, are most common in HIV-infected persons. Each of these parasites can infect the digestive tract, and sometimes two or more can cause infection at the same time.
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.

The oocytes may be seen by microscopic examination of a stool sample, but they may be confused with other objects or artifacts similar in appearance. [18] Most cryptosporidia are 3–6 μm in size, although some reports have described larger cells. [18] Boiling is believed to be the safest option for water contaminated by Cryptosporidium. [19 ...
This is a shortened version of the first chapter of the ICD-9: Infectious and Parasitic Diseases. It covers ICD codes 001 to 139. The full chapter can be found on pages 49 to 99 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
A study on parasites in stool samples in the United States during 2000 found blastocystosis to be the most common parasitic infection in the population, occurring in 23% of individuals. [90] [92] A Canadian study of samples received in 2005 identified Blastocystis as the most prevalent protozoal infection identified. [91]
Giardiasis is a parasitic disease caused by Giardia duodenalis (also known as G. lamblia and G. intestinalis). [3] Infected individuals who experience symptoms (about 10% have no symptoms) may have diarrhea, abdominal pain, and weight loss. [1] Less common symptoms include vomiting and blood in the stool. [1]
However, they did not find the parasite in dog stool, bird stool, cattle dung, vegetable samples, or water samples. They concluded that pool water contaminated via environmental pollution might have caused the infection, as the parasite can resist chlorination in water. [6] Cyclosporiasis infections have been well reported in Nepal.
