ICD-10 Code B17 – Other acute viral hepatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B17 – Other acute viral hepatitis
What it is
B17 identifies an acute viral hepatitis that is not classified elsewhere in the ICD-10-CM system. Use it for a recent viral liver infection when the specific virus is not otherwise coded here.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include jaundice, fatigue, nausea, abdominal discomfort, dark urine, and elevated liver enzymes in an acute hepatitis picture.
When to use this code
Use B17 when the provider documents acute viral hepatitis but does not specify a more precise type in the available record. It also fits cases described as other acute viral hepatitis or an acute viral hepatitis not otherwise classified. Check documentation if the virus is named elsewhere.
Do not use for
Do not use B17 for chronic viral hepatitis or for acute hepatitis with a clearly identified code in another category. If the record supports a different specific viral hepatitis diagnosis, code that instead.
Coding tip
Review the provider’s wording carefully and code the most specific acute viral hepatitis diagnosis documented.
