Enterobiasis

This code represents an intestinal parasitic infection caused by the pinworm, Enterobius vermicularis. It is characterized by pruritus ani, especially at night, and can affect individuals of all ages, though it is most common in children. The infection is typically benign but can cause discomfort and, in rare cases, more serious complications.

Use this code when documentation confirms a diagnosis of pinworm infection, oxyuriasis, or threadworm infection. This diagnosis is often made based on clinical symptoms and confirmed by microscopic identification of eggs or adult worms, typically using the "scotch tape test."

• Do not confuse with other helminthic infections; ensure the documentation specifically identifies pinworms.
• This code is for the infection itself; any associated symptoms (e.g., pruritus) would be coded separately if they represent distinct conditions or require additional treatment.
• Consider Z20.828 (Contact with and (suspected) exposure to other viral communicable diseases) if documenting exposure without confirmed infection.
