Trichinellosis

This code represents an infection caused by parasitic roundworms of the Trichinella genus, typically acquired by consuming undercooked meat containing the larvae. The infection can manifest with gastrointestinal symptoms, muscle pain, fever, and periorbital edema as larvae migrate and encyst in muscle tissue.

This code is used when documentation confirms a diagnosis of trichinellosis, often supported by serological tests, muscle biopsy, or identification of larvae. It applies to cases where the patient presents with symptoms consistent with the parasitic infection and a definitive diagnosis has been established.

• Ensure documentation specifies Trichinella species infection; do not use for other helminthic infections.
• Consider sequencing this code as the primary diagnosis when trichinellosis is the reason for the encounter.
• Review for associated manifestations (e.g., myalgia, eosinophilia) that may require additional codes.
