Short answer: The hepatitis A vaccine is not one of the routine vaccines listed under the Medicare Part B preventive vaccine benefit. Medicare Part D generally covers adult vaccines recommended by the Advisory Committee on Immunization Practices when they are medically necessary to prevent illness. This can include hepatitis A vaccination for a person who meets current recommendation criteria.
Original Medicare coverage
Original Medicare Part A and Part B do not include ordinary outpatient Part D drug coverage. A person must have a stand-alone Medicare drug plan or a Medicare Advantage plan with drug coverage to use the Part D vaccine benefit. Part B covers flu, pneumococcal, COVID-19, and qualifying hepatitis B vaccines. It may cover another vaccine when it is directly related to treating an injury or exposure, under separate rules.
Eligibility and limits
Part D vaccine coverage depends on the vaccine being commercially available, medically necessary to prevent illness, and covered under current federal requirements. The prescriber or pharmacist should determine whether the person meets current public-health recommendations. Travel circumstances, medical risk, prior doses, and the vaccine series can affect what is needed.
This page explains insurance coverage only. A health care professional should determine whether vaccination is appropriate and how many doses are required.
Costs
A Part D plan does not charge a deductible or copayment for adult vaccines recommended by the Advisory Committee on Immunization Practices. The pharmacy or provider must process the vaccine through the drug benefit correctly. A separate medical visit may have cost sharing.
Medicare Advantage
A Medicare Advantage plan with drug coverage generally processes the hepatitis A vaccine through its Part D benefit. A Medicare Advantage plan without drug coverage may not include the outpatient vaccine benefit. Use a network pharmacy or follow the plan’s instructions.
What to do next
- Ask a health care professional whether you meet current hepatitis A vaccine recommendations.
- Call the Part D plan or check its vaccine instructions.
- Use a pharmacy or provider able to bill the plan.
- Keep a record of each dose in the series.
Coverage is determined from the claim, the patient’s eligibility, provider status, and applicable Medicare rules. A provider’s recommendation does not guarantee payment. Before a planned service, ask the provider what will be billed and ask Medicare or the plan whether any coverage review is required.
