Rotaviral enteritis

This code represents an inflammation of the small intestine caused specifically by rotavirus. It typically presents as acute gastroenteritis with symptoms such as severe watery diarrhea, vomiting, fever, and abdominal pain, primarily affecting infants and young children.

Use this code when documentation explicitly states a diagnosis of rotaviral enteritis or gastroenteritis confirmed to be due to rotavirus. This diagnosis is often supported by laboratory testing, such as stool antigen detection or PCR for rotavirus.

• Do not use this code for unspecified viral enteritis; specific documentation of rotavirus is required.
• Consider sequencing this code as the primary diagnosis when rotaviral enteritis is the reason for the encounter.
• Distinguish from other viral enteritis codes (e.g., A08.3x for other viral enteritis) based on definitive rotavirus identification.
