Mixed intestinal helminthiases

This code signifies a parasitic infection of the intestines involving simultaneous infestation by two or more different species of helminths (worms). These helminths can include nematodes (roundworms), cestodes (tapeworms), or trematodes (flukes), leading to a variety of gastrointestinal symptoms and potential systemic effects. The specific helminth species are not individually identified by this code, only their co-occurrence.

Use this code when diagnostic testing (e.g., stool ova and parasite examination) confirms the presence of multiple distinct helminth species in the intestinal tract. This code is appropriate when the medical record clearly documents a mixed helminthic infection without specifying individual helminth codes for each identified parasite.

• Do not use this code if only one helminth species is identified; instead, code the specific helminth.
• If individual helminth species are documented, code each specific helminth separately rather than using this generalized code.
• Ensure documentation explicitly states "mixed" or "multiple" helminth infections to support the use of this code.
