ICD-10 Code B19.9 – Unspecified Viral Hepatitis Without Hepatic Coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B19.9 – Unspecified viral hepatitis without hepatic coma
What it is
B19.9 identifies viral hepatitis when the type is not specified and there is no hepatic coma. Use it for a documented viral hepatitis diagnosis without a named virus or clear subtype.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include hepatitis symptoms and evidence of liver inflammation, but the specific virus and severity are not identified.
When to use this code
Use B19.9 when the provider documents viral hepatitis but does not specify the viral type, such as hepatitis A, B, C, or another defined cause. It also fits when the record states hepatitis without coma and no further detail is available. Check documentation if the chart later identifies a specific hepatitis type.
Do not use for
Do not use this code if the record identifies a specific viral hepatitis type or if hepatic coma is documented. Also avoid it when the diagnosis is nonviral or when coding guidance points to a more specific hepatitis code.
Coding tip
Query the provider for the exact hepatitis type whenever the record is unclear, because a more specific code may be available.
