ICD-10 Code B00.81 – Herpesviral hepatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B00.81 – Herpesviral hepatitis
What it is
B00.81 identifies hepatitis caused by herpesvirus infection, most often herpes simplex virus. Use it when documentation shows liver inflammation attributed to herpesviral disease.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include acute hepatitis with abdominal pain, jaundice, elevated liver enzymes, and evidence of herpesvirus infection.
When to use this code
Use this code when the provider documents herpesviral hepatitis, herpes simplex hepatitis, or hepatitis due to herpesvirus. It is appropriate when the liver involvement is clearly linked to the viral infection. Check documentation if the record only notes hepatitis without a stated herpes cause.
Do not use for
Do not use B00.81 for nonspecific viral hepatitis or hepatitis from another identified cause. Also avoid it when herpes infection is present without documented hepatic involvement.
Coding tip
Confirm that the chart links hepatitis to herpesvirus before assigning B00.81.
