A08.0 ICD-10-CM Code: Rotaviral enteritis

A08.0 is the ICD-10-CM diagnosis code for rotaviral enteritis. Rotavirus is a common viral infection that causes inflammation of the stomach and intestines, leading to diarrhea, vomiting, and abdominal discomfort. It is most common in young children but can affect people of any age. A08.0 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering intestinal infectious diseases (a00-a09).

A08.0 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

Rotaviral enteritis is typically an acute, self-limiting condition; ensure documentation specifies rotavirus as the causative agent rather than other viral gastroenteritis.
