Other specified protozoal intestinal diseases

This code represents a diagnosis of protozoal infections primarily affecting the intestines, which are not specifically classified elsewhere. It covers a range of parasitic diseases caused by single-celled organisms that colonize the gastrointestinal tract, leading to various symptoms such as diarrhea, abdominal pain, and malabsorption.

Apply this code when documentation specifies a protozoal intestinal infection that does not have a more specific ICD-9-CM code available. This includes conditions like Balantidiasis, Isosporiasis, or Sarcocystosis when the specific protozoal agent is identified and its primary site of infection is the intestine. Documentation should clearly state the protozoal etiology and intestinal involvement.

• Ensure the documentation explicitly states "protozoal" and "intestinal" and that no more specific code (e.g., for Giardiasis or Amebiasis) is applicable.
• Do not use for bacterial, viral, or other non-protozoal intestinal infections.
• Consider sequencing with codes for associated symptoms (e.g., diarrhea, dehydration) if they are treated and not inherent to the primary diagnosis.
