Adenoviral enteritis

This code represents an inflammation of the intestines caused specifically by an adenovirus infection. Patients typically present with symptoms such as diarrhea, vomiting, fever, and abdominal pain, often resembling other forms of gastroenteritis. The condition is generally self-limiting but can be more severe in immunocompromised individuals or young children.

This code is appropriate when documentation clearly identifies adenovirus as the causative agent of enteritis. It should be used for confirmed cases of adenoviral infection affecting the gastrointestinal tract. Supporting documentation would include laboratory test results (e.g., stool PCR, antigen detection) confirming the presence of adenovirus.

• Ensure the documentation specifies "adenovirus" as the etiology; otherwise, use a more general code for viral enteritis.
• Do not confuse with other viral gastroenteritis codes (e.g., rotaviral, noroviral) unless adenovirus is explicitly identified.
• If dehydration is also present, code it as a secondary diagnosis.
