2025 ICD-10-CM code A08.3
Other viral enteritis. This code represents viral enteritis not otherwise specified in the ICD-10-CM.
Medical necessity is established by the presence of symptoms such as diarrhea, vomiting, and dehydration due to a viral infection of the intestines. The severity of symptoms and need for rehydration therapy further justify the medical necessity.
Clinicians should diagnose and manage viral enteritis, including assessing dehydration severity, administering fluids, and providing patient education on preventive measures like handwashing. Lab tests may be ordered to identify the causative agent or rule out other pathogens.
In simple words: This code refers to a general viral infection of the intestines, causing inflammation and symptoms like diarrhea, vomiting, and abdominal pain.It's used when the specific virus causing the infection isn't identified by other, more precise codes.
Other viral enteritis is an inflammation of the intestines caused by a virus not specifically identified by other codes within the category. Symptoms can include watery diarrhea, vomiting, abdominal pain, and fever, which can lead to dehydration in severe cases. Diagnosis involves laboratory tests of fecal matter to rule out bacterial or parasitic causes and possibly identify the viral antigen. Treatment focuses on rehydration through oral or intravenous fluids, as antibiotics are ineffective against viruses.
Example 1: A patient presents with severe watery diarrhea, vomiting, and abdominal pain after consuming contaminated food. Lab tests rule out bacterial and parasitic infections, leading to a diagnosis of other viral enteritis (A08.3)., A child experiences persistent diarrhea and fever. After testing negative for Rotavirus and other specific viral enteritis, the physician diagnoses the condition as other viral enteritis (A08.3)., A patient develops diarrhea and dehydration during a community outbreak of viral gastroenteritis.While the specific virus is not definitively identified in this patient, A08.3 is used to code the diagnosis.
Documentation should include signs and symptoms, relevant lab results (e.g., stool tests), and details of rehydration therapy.If a specific virus is suspected but not confirmed, this should be noted.
** Excludes1: influenza with involvement of gastrointestinal tract (J09.X3, J10.2, J11.2). Use additional code to identify resistance to antimicrobial drugs (Z16.-).
