ICD-10 Code B19.2 – Unspecified Viral Hepatitis C (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B19.2 – Unspecified viral hepatitis C
What it is
B19.2 identifies viral hepatitis C when the record does not specify acute, chronic, or another more detailed form. Use it for documented hepatitis C infection without further classification.
Clinical signs
Clinical features vary; refer to documentation. Patients may have no symptoms or may show signs of hepatitis such as fatigue, jaundice, abdominal discomfort, or abnormal liver findings.
When to use this code
Use this code when the provider documents hepatitis C or viral hepatitis C without stating whether it is acute or chronic. It also fits when the chart confirms hepatitis C but lacks enough detail for a more specific code.
If later documentation identifies a more specific hepatitis C category, code that instead. Check documentation for confirmed diagnosis wording and any associated liver disease.
Do not use for
Do not use B19.2 for hepatitis C that is clearly documented as chronic, acute, or another specified type. Do not assign it when hepatitis C is only suspected or ruled out.
Coding tip
Look for the exact provider wording; if the type of hepatitis C is stated, choose the more specific code.
