What This Code Means

Astrovirus enteritis is an infection of the stomach and intestines caused by the astrovirus, a virus that typically causes watery diarrhea, nausea, and vomiting. This condition is most common in young children, elderly people, and those with weakened immune systems.

Coding Tips

• •Verify that astrovirus has been confirmed through laboratory testing (stool culture or antigen detection) before assigning this code, as it requires specific identification rather than presumptive diagnosis
• •Do not use this code for other viral gastroenteritis cases; ensure documentation specifically mentions astrovirus to differentiate from other viral causes like rotavirus or norovirus
