    ICD-10-CM Code For Acute Hepatitis A: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B15 includes codes for acute hepatitis A infection and its clinical presentations, such as symptomatic acute liver inflammation due to hepatitis A virus. These ICD-10-CM diagnosis codes are used to document episodes of acute viral hepatitis A, capturing disease severity, organ involvement, and clinical complexity relevant to liver injury and systemic symptoms. Accurate coding within the ICD-10-CM B15 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden onset high fever, severe malaise, anorexia, nausea, right upper quadrant abdominal pain, and jaundice after recent travel to a region with known hepatitis A outbreaks. Laboratory evaluation shows markedly elevated aminotransferases and positive hepatitis A IgM confirming an acute infection, so an acute hepatitis A diagnosis is assigned at the encounter. Typical codes: B15.0, B15.9
    • A pediatric patient is brought to urgent care with low-grade fever, vomiting, diffuse abdominal discomfort, and new onset jaundice following exposure to a household contact with confirmed hepatitis A; outpatient laboratory testing demonstrates hepatitis A IgM positive, and the child is managed conservatively with follow-up. Because this is a new, self-limited viral hepatitis A infection identified in the clinic setting, an acute hepatitis A code is used. Typical codes: B15.0, B15.9
    • An adult with previously diagnosed acute hepatitis A is hospitalized for fulminant hepatic failure characterized by coagulopathy, encephalopathy, and rising bilirubin levels requiring intensive monitoring and supportive care; testing confirms hepatitis A as the etiologic agent, so an acute hepatitis A diagnosis is documented as the underlying cause of the current hepatic decompensation. Typical codes: B15.0, B15.9
