Metagonimiasis

This code represents metagonimiasis, an intestinal fluke infection caused by the parasite Metagonimus yokogawai. It is acquired by consuming raw or undercooked freshwater fish containing metacercariae, leading to inflammation and ulceration of the small intestine.

Use this code when documentation confirms a diagnosis of metagonimiasis, typically identified through microscopic examination of stool samples revealing characteristic parasite eggs. This diagnosis is common in endemic areas, particularly in Asia, following a history of consuming raw fish.

• Differentiate from other intestinal fluke infections; each has a specific ICD-9-CM code.
• Ensure the physician's documentation explicitly states "metagonimiasis" or identifies Metagonimus yokogawai.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, followed by any associated symptoms or complications.
