Taenia solium taeniasis

This code represents an intestinal infection caused by the adult pork tapeworm, Taenia solium. Individuals acquire this infection by ingesting undercooked pork containing larval cysts (cysticerci), leading to the development of an adult tapeworm in the small intestine. Symptoms can range from asymptomatic to abdominal discomfort, nausea, and diarrhea.

Assign this code when documentation confirms the presence of an adult Taenia solium tapeworm in the human gastrointestinal tract. This diagnosis is typically supported by microscopic identification of Taenia solium proglottids or eggs in stool samples. It should be used when the patient presents with symptoms directly attributable to the intestinal tapeworm.

• Differentiate from cysticercosis (larval infection), which is coded separately.
• Ensure the documentation specifies Taenia solium to avoid confusion with other Taenia species.
• Do not use if the patient has neurocysticercosis or other extra-intestinal manifestations of Taenia solium infection; these have distinct codes.
