Trichostrongyliasis

This code represents an infection caused by nematodes of the genus Trichostrongylus, which are intestinal parasites. Humans typically acquire trichostrongyliasis through the ingestion of infective larvae, often from contaminated vegetation. The infection is generally mild, characterized by gastrointestinal symptoms such as abdominal pain, diarrhea, and nausea.

Use this code when documentation confirms a diagnosis of trichostrongyliasis, typically identified through microscopic examination of stool samples revealing Trichostrongylus eggs. This code is appropriate for cases where the patient presents with symptoms consistent with a parasitic intestinal infection and laboratory findings confirm the presence of this specific helminth.

• Ensure laboratory confirmation of Trichostrongylus species before assigning this code.
• Do not confuse with other helminthic infections; verify the specific parasite identified.
• Code any associated symptoms (e.g., diarrhea, abdominal pain) as secondary diagnoses if documented and clinically significant.
