Cyclosporiasis

This code identifies an intestinal infection caused by the microscopic parasite Cyclospora cayetanensis. It typically manifests as watery diarrhea, abdominal cramps, nausea, and fatigue, often lasting for several weeks. The infection is acquired by consuming contaminated food or water.

Assign this code when documentation confirms a diagnosis of cyclosporiasis, usually following laboratory identification of Cyclospora oocysts in stool samples. It is appropriate for both acute and persistent infections. This code should be used when the patient presents with symptoms consistent with the infection and a definitive diagnosis has been made.

• Do not confuse with other parasitic enteritis codes; ensure Cyclospora is specifically documented.
• Sequence as the primary diagnosis when cyclosporiasis is the reason for the encounter.
• Look for documentation of laboratory confirmation (e.g., stool ova and parasite exam) to support the diagnosis.
