ICD-10 Code B17.8 – Other specified acute viral hepatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B17.8 – Other specified acute viral hepatitis
What it is
B17.8 identifies an acute viral hepatitis infection that does not fit a more specific hepatitis code. Use it when documentation states another specified viral cause or presentation, but not hepatitis A, B, C, D, or E.
Clinical signs
Typical findings include acute liver inflammation with jaundice, fatigue, nausea, abdominal discomfort, or dark urine. Clinical features vary; refer to documentation for the exact viral cause and presentation.
When to use this code
Use B17.8 when the provider documents acute viral hepatitis with a specified viral agent or description that is not classified elsewhere. It may also fit cases labeled as “other specified” acute viral hepatitis when the record does not support a more specific code. Check documentation if the virus is not named.
Do not use for
Do not use this code for chronic viral hepatitis, or when the record supports hepatitis A, B, C, D, or E. If the diagnosis is uncertain or unspecified, check documentation before assigning B17.8.
Coding tip
Code the documented viral hepatitis type first if a more specific ICD-10-CM option is available.
