ICD-10 Code A08.0 – Rotaviral enteritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A08.0 – Rotaviral enteritis
What it is
A08.0 identifies rotaviral enteritis, an intestinal infection caused by rotavirus. It is used when the record documents rotavirus as the cause of acute gastroenteritis.
Clinical signs
Typical features include acute diarrhea, vomiting, abdominal discomfort, and dehydration, especially in infants and young children. Clinical features vary; refer to documentation.
When to use this code
Use A08.0 when the provider clearly documents rotaviral gastroenteritis, rotavirus enteritis, or rotavirus infection causing diarrhea. Code it from the final diagnosis or confirmed assessment, not from a suspected cause alone. Check documentation if the organism is not specified.
Do not use for
Do not use A08.0 for noninfectious diarrhea or gastroenteritis from another identified cause. If the record does not confirm rotavirus, use the documented diagnosis instead.
Coding tip
Confirm that rotavirus is named in the assessment or discharge diagnosis before assigning A08.0.
