ICD-10 Code B19.10 – Unspecified viral hepatitis B without hepatic coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B19.10 – Unspecified viral hepatitis B without hepatic coma
What it is
This code describes viral hepatitis B when the record does not specify the exact type or acute/chronic status, and there is no hepatic coma. Use it for documented hepatitis B infection without additional detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly, hepatitis B may present with jaundice, fatigue, abdominal discomfort, dark urine, or elevated liver enzymes, but you should not assume these findings are present unless recorded.
When to use this code
Use this code when the provider documents hepatitis B as unspecified and does not identify a more precise category. It also applies when the record confirms viral hepatitis B without hepatic coma, but the chart lacks enough detail for a specific subtype.
Do not use for
Do not use this code if the documentation specifies acute, chronic, or another defined form of hepatitis B. Also avoid it when hepatic coma is present or when the diagnosis is a different viral hepatitis type.
Coding tip
Check the note for specificity first; if the record names a more exact hepatitis B diagnosis, code that instead of an unspecified option.
