ICD-10 Code B15.0 – Hepatitis A with hepatic coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B15.0 – Hepatitis A with hepatic coma
What it is
This code identifies acute hepatitis A infection complicated by hepatic coma. Use it when documentation shows hepatitis A and a coma state attributable to severe liver dysfunction.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include acute jaundice, marked liver dysfunction, and altered mental status progressing to coma in the setting of hepatitis A.
When to use this code
Use B15.0 when the provider documents hepatitis A with hepatic coma, acute liver failure, or coma caused by hepatitis A. You should ensure the record clearly links the coma to the hepatitis infection. If the coma is not specified as hepatic, check documentation.
Do not use for
Do not use this code for uncomplicated hepatitis A or for coma from another cause. If hepatic coma is not documented, or the liver disease is due to a different hepatitis type, choose the more accurate code.
Coding tip
Verify that both hepatitis A and hepatic coma are documented together before assigning B15.0.
