Taenia solium infection, intestinal form

This code represents an intestinal infection caused by the pork tapeworm, Taenia solium. It specifically refers to the presence of the adult tapeworm in the human gastrointestinal tract, leading to symptoms such as abdominal pain, nausea, diarrhea, and weight loss. This condition is acquired by ingesting undercooked pork containing T. solium larvae.

Use this code when documentation confirms the presence of an adult Taenia solium tapeworm in the intestines. This diagnosis is typically supported by microscopic identification of T. solium eggs or proglottids in stool samples, or less commonly, by visualization of the adult worm. It applies to cases where the infection is limited to the intestinal lumen.

• Differentiate carefully from cysticercosis (infection with the larval stage of T. solium), which has distinct ICD-9-CM codes.
• Ensure documentation specifies Taenia solium and not other tapeworm species, as other taeniasis infections are coded differently.
• This code is for the intestinal form; do not use if the infection has disseminated to other tissues.
