ICD-10 Code B19.20 – Unspecified viral hepatitis C without hepatic coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B19.20 – Unspecified viral hepatitis C without hepatic coma
What it is
B19.20 identifies viral hepatitis C when the record does not specify acute or chronic disease and there is no hepatic coma. Use it for documented hepatitis C infection that is otherwise unspecified.
Clinical signs
Clinical features vary; refer to documentation. Patients may have hepatitis C noted by a clinician, with or without nonspecific liver-related symptoms, but the chart must support viral hepatitis C.
When to use this code
Use B19.20 when the provider documents hepatitis C but does not state whether it is acute, chronic, or another form. It also fits when hepatic coma is not present and no more specific code is supported. If the record later clarifies the type, code the more specific diagnosis instead.
Do not use for
Do not use this code for chronic hepatitis C when that diagnosis is documented. Do not use it if the chart specifies hepatic coma or another hepatitis type; check documentation.
Coding tip
Query for specificity whenever hepatitis C is mentioned without an acute or chronic designation.
