Trichostrongyliasis

This code identifies an intestinal infection caused by parasitic roundworms of the genus Trichostrongylus. Humans typically acquire trichostrongyliasis through ingestion of contaminated vegetation, leading to symptoms such as abdominal pain, diarrhea, and malabsorption. The severity of symptoms often correlates with the worm burden.

Assign this code when documentation confirms a diagnosis of trichostrongyliasis, typically through identification of Trichostrongylus eggs in stool samples. This code is appropriate for both symptomatic and asymptomatic infections. Ensure the medical record clearly states the diagnosis of trichostrongyliasis.

• Differentiate from other helminthic infections; specific identification of Trichostrongylus is key.
• Consider co-occurring nutritional deficiencies (e.g., anemia) as secondary diagnoses.
• Review documentation for the specific species of Trichostrongylus if available, though this code covers the genus broadly.
