Giardiasis

This code represents an intestinal infection caused by the microscopic parasite Giardia lamblia. It is a common cause of waterborne disease, leading to symptoms such as diarrhea, abdominal cramps, bloating, and nausea. The infection can be acute or chronic, with malabsorption occurring in some cases.

Use this code when documentation confirms a diagnosis of giardiasis, typically identified through stool examination for Giardia cysts or trophozoites. This applies to both symptomatic and asymptomatic carriers identified during screening or contact tracing. Supporting documentation should include laboratory results confirming the presence of the parasite.

• Differentiate from other parasitic intestinal infections; ensure Giardia is specifically identified.
• Consider sequencing with codes for associated symptoms (e.g., diarrhea, abdominal pain) if they are not integral to the giardiasis diagnosis itself and represent additional conditions.
• Do not use for suspected giardiasis without definitive diagnostic confirmation.
