ICD-10 Code A08.39 – Other viral enteritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A08.39 – Other viral enteritis
What it is
A08.39 identifies viral inflammation of the intestines caused by a virus not otherwise specified by a more exact code. Use it when documentation states other viral enteritis and does not name a specific organism.
Clinical signs
Typical findings include acute diarrhea, abdominal cramps, nausea, vomiting, and sometimes low-grade fever. Clinical features vary; refer to documentation when the record does not clearly describe a viral cause.
When to use this code
Use this code when the clinician documents other viral enteritis, viral gastroenteritis, or a similar viral intestinal infection without a more specific ICD-10 option. It fits cases where the source is viral but the exact virus is not identified. Check documentation if the note is ambiguous.
Do not use for
Do not use this code for bacterial, parasitic, or noninfectious gastrointestinal conditions. Also avoid it when the chart supports a more specific viral enteritis code or another diagnosis entirely.
Coding tip
Code from the provider’s wording; if the organism is named, verify whether a more specific ICD-10 code applies.
