Ascariasis

This code represents an intestinal infection caused by the roundworm Ascaris lumbricoides. The infection typically occurs when an individual ingests eggs from contaminated soil or food, leading to adult worms residing in the small intestine. Symptoms can range from asymptomatic to abdominal pain, malnutrition, and in severe cases, intestinal obstruction or biliary tract obstruction.

Use this code when documentation confirms a diagnosis of ascariasis, often identified through microscopic examination of stool samples revealing Ascaris eggs or the passage of adult worms. This code is appropriate for both symptomatic and asymptomatic presentations of the infection.

• Ensure the documentation specifies ascariasis and not another helminthic infection.
• Consider additional codes for any associated complications, such as intestinal obstruction or malnutrition.
• Do not confuse with other parasitic infections of the intestine, such as enterobiasis or hookworm.
