Understanding Medicare Vaccine Coverage: What beneficiaries need to know about Part B and Part D benefits

INDIANA Navigating Medicare benefits can raise important questions for older adults and individuals with disabilities, especially regarding which vaccines are covered and how out-of-pocket costs are handled.

According to guidance from the State Health Insurance Assistance Program (SHIP), many essential vaccines are covered under Medicare Part B or Medicare Part D. However, specific eligibility criteria—such as age, underlying risk factors, and recommended dosing intervals—determine how coverage is applied.

Vaccines Covered Under Medicare Part B (No Copays or Deductibles)

Under Medicare Part B, several routine and preventive vaccines are classified as free benefits, meaning beneficiaries face zero out-of-pocket costs, copayments, or deductibles:

  • COVID-19: Coverage for COVID-19 immunizations remains fully intact under Part B, even following the conclusion of the public health emergency.
  • Annual Flu Shot: Fully covered as an annual preventive measure, typically administered ahead of peak flu season.
  • Pneumonia: Covered to protect against severe pneumococcal infections. Depending on medical guidelines, Part B covers either a single-dose vaccine or a two-dose series spaced at least one year apart for most adults aged 65 and older.
  • Hepatitis B: Covered as a preventive benefit for individuals assessed at medium or high risk for contracting the virus.
  • Tetanus (Treatment-Related): Covered by Part B if administered as medical treatment following an acute injury, such as a severe cut or wound.

Vaccines Covered Under Medicare Part D Prescription Plans

Other preventive vaccines are covered through standalone Medicare Part D prescription plans or Medicare Advantage plans with drug coverage. Beneficiaries enrolled in these plans may be subject to plan deductibles or copayments depending on their specific policy:

  • Shingles: Recommended by the CDC for adults 50 and older. Coverage applies to the two-dose Shingrix series, spaced two to six months apart.
  • RSV (Respiratory Syncytial Virus): FDA-approved for adults aged 60 and older to protect against severe respiratory complications, which can aggravate conditions like asthma or COPD.
  • Tdap (Tetanus, Diphtheria, Pertussis): Covered for routine preventive care, with the CDC recommending a Tdap or Td booster every 10 years. Routine tetanus boosters for preventive maintenance fall under Part D rather than Part B.
  • Hepatitis A & Low-Risk Hepatitis B: Covered under Part D for individuals recommended by the CDC to receive Hepatitis A protection, as well as Hepatitis B shots for individuals determined to be at low risk.
