A07.1

What This Code Means

Giardiasis is an intestinal infection caused by a parasite called Giardia that spreads through contaminated water or food, causing diarrhea, stomach cramps, and nausea. It is commonly acquired from drinking untreated water or traveling to areas with poor sanitation.

Coding Tips

• •Verify the documentation specifies giardiasis or lambliasis (alternate name) to ensure accurate code selection; do not assume based on symptoms alone
• •This code does not require a severity modifier; document the clinical presentation (acute vs. chronic diarrhea) in the medical record for clinical context, though the ICD-10 code remains the same
