Intestinal strongyloidiasis

This code represents an infection of the human gastrointestinal tract by the parasitic nematode Strongyloides stercoralis. The infection can be chronic and often asymptomatic, but may manifest with gastrointestinal, pulmonary, or dermatologic symptoms. In immunocompromised individuals, it can lead to a severe, disseminated hyperinfection syndrome.

Use this code when documentation confirms a diagnosis of strongyloidiasis specifically affecting the intestines. This typically includes positive stool ova and parasite examination, serology, or duodenal aspirate findings. It is appropriate for both acute and chronic intestinal strongyloidiasis.

• Do not use this code for strongyloidiasis affecting other organs; look for more specific codes if the infection is disseminated.
• Ensure documentation specifies "intestinal" strongyloidiasis to support this code.
• Consider co-occurring conditions, especially immunosuppression, which may impact treatment and prognosis.
