Screening examination for intestinal helminthiasis

This code signifies a screening encounter specifically aimed at detecting the presence of parasitic worms (helminths) within the intestinal tract. It is used when a patient presents for a check-up to identify potential asymptomatic infections, rather than for the investigation of existing symptoms.

This code is appropriate for routine screenings in high-risk populations, such as individuals traveling to or residing in endemic areas, or those with occupational exposure. It can also be used for public health initiatives or school-based screening programs designed to identify intestinal helminthiasis in asymptomatic individuals.

• Do not use this code if the patient is presenting with symptoms suggestive of helminthiasis; in such cases, a definitive diagnosis code or a symptom code should be used.
• This code should be sequenced as the primary diagnosis when the sole purpose of the encounter is screening.
• Consider any associated findings or definitive diagnoses that may be identified during the screening, and code them accordingly in addition to the screening code.
