Capillariasis

This code represents an infection caused by parasitic nematodes of the genus Capillaria. These infections can manifest in various organ systems, including the intestines, liver, and lungs, depending on the specific Capillaria species involved. Symptoms vary widely from asymptomatic to severe gastrointestinal distress, hepatitis, or respiratory issues.

Use this code when documentation confirms a diagnosis of capillariasis, typically through microscopic identification of Capillaria eggs or adult worms in stool, biopsy, or sputum samples. This code is appropriate for all forms of human capillariasis, such as intestinal capillariasis (Capillaria philippinensis) or hepatic capillariasis (Capillaria hepatica).

• Ensure the physician's documentation explicitly states "capillariasis" or identifies a specific Capillaria species.
• Do not confuse this with other helminthic infections; confirm the parasitic genus.
• Code any associated symptoms or complications (e.g., malnutrition, liver damage) separately as secondary diagnoses.
