ICD-10 Code B15.9 – Hepatitis A without hepatic coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B15.9 – Hepatitis A without hepatic coma
What it is
B15.9 identifies an acute hepatitis A infection without hepatic coma. Use it when documentation confirms hepatitis A, but there is no mention of hepatic coma or acute liver failure.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may mention jaundice, fatigue, nausea, abdominal discomfort, or elevated liver enzymes, but the diagnosis should be explicitly recorded.
When to use this code
Use B15.9 when the provider documents hepatitis A and does not describe hepatic coma. It also fits cases where the record clearly states hepatitis A infection without severe neurologic or liver-failure complications. If the chart only says “hepatitis” or is unclear, check documentation before coding.
Do not use for
Do not use this code for hepatitis A with hepatic coma, which requires a different code. Also avoid it when the record does not specifically identify hepatitis A.
Coding tip
Confirm the organism and complication status in the assessment or discharge diagnosis before assigning B15.9.
