Medicare Part D Vaccine Coverage: Costs and Benefits
Understanding Medicare Vaccine Coverage: Part B vs. Part D
Medicare offers vital vaccine protection, but the landscape can be confusing without detailed guidance. The clear distinction between Medicare Part B and Part D vaccine coverage shapes your costs, access, and choices. Knowing which part covers what ensures you are fully protected and don’t miss key preventive shots.
Medicare Part B Vaccine Coverage: Limited but Essential
Medicare Part B primarily covers a select group of preventive vaccines aimed at combatting widespread, serious illnesses. These are available at no cost to most beneficiaries, aside from special cases:
- Influenza (flu) vaccine – available annually
- Pneumococcal (pneumonia) vaccine – one or two doses depending on risk factors
- COVID-19 vaccine – included as an essential preventive service
- Hepatitis B vaccine – for those at medium or high risk; subject to deductible and coinsurance
- Vaccines after acute exposure (like tetanus after an injury) – coverage depends on circumstance
These vaccines are obtained through a network physician or, at times, a participating pharmacy. If you’re unsure if your doctor is in-network, check out this guide on finding a Medicare-accepting doctor.
Medicare Part D Vaccine Coverage: Broader and Now No-Cost
Medicare Part D vaccine coverage is much broader, embracing most vaccines recommended for adults by the Advisory Committee on Immunization Practices (ACIP). Importantly, since 2023, Part D vaccines are provided at no cost-no copayments or deductibles-thanks to the Inflation Reduction Act. This means every ACIP-recommended adult vaccine, not already covered under Part B, is available free through your plan.
Common examples of Medicare Part D vaccine coverage include:
- Shingles vaccine (Shingrix)
- RSV vaccine (Respiratory Syncytial Virus) for those 60 and older
- Tdap vaccine (tetanus, diphtheria, pertussis)
- Hepatitis A and B vaccines (if not already covered under Part B)
- HPV (human papillomavirus) vaccine
- Mpox (formerly monkeypox) vaccine
- MMR vaccine (measles, mumps, rubella)
- Travel vaccines-coverage may depend on your plan
Key Differences at a Glance
| Aspect | Part B | Part D |
|---|---|---|
| Vaccines Covered | Flu, pneumococcal, COVID-19, Hepatitis B (at risk), acute exposure only | Shingles, RSV, Tdap, Hepatitis A, HPV, Mpox, MMR, most travel vaccines, others |
| Cost to You | Free (Hep B: 80% after deductible) | Completely free (no copay or deductible) |
| Where to Get Vaccines | Network physician or pharmacy | Network pharmacy or plan-approved provider |
| Coverage Start | Ongoing for covered vaccines | No-cost coverage began in 2023 |
Understanding this division can help you plan your care and avoid unnecessary out-of-pocket costs. For more details on what you might pay for other health costs, see our guide to Medicare out-of-pocket costs (TrOOP).
Which Vaccines Are Covered Under Medicare Part D?
All commercially available ACIP recommended vaccines for adults are covered by most Medicare Part D plans, provided they are not already listed under Part B. This ensures comprehensive immunization options-including as new vaccines are recommended by ACIP or released to the market.
Complete List of Key Part D-Covered Vaccines (2024)
- Shingles Vaccine (Shingrix): Essential for adults 50+, especially as risk of shingles rises with age. Shingles vaccine Medicare coverage now comes with no out-of-pocket cost.
- RSV Vaccine: Recommended for adults 60+ and those over 75 by the CDC. RSV vaccine Medicare coverage is also at zero cost now.
- Tdap Vaccine: Protects against tetanus, diphtheria, and pertussis. Important especially for caregivers of infants.
- Hepatitis A and B Vaccines: Accessible via Part D when not meeting criteria for Part B.
- HPV Vaccine: Human papillomavirus for indicated adults.
- Mpox Vaccine: Previously known as monkeypox, offered based on risk/exposure.
- MMR Vaccine: Measles, mumps, rubella where required.
- Travel Vaccines: Including typhoid, yellow fever, meningococcal, as determined by individual Part D plan coverage.
If you plan a trip, check your plan’s formulary or discuss with your provider.
Part D plans must include most ACIP-recommended vaccines on their formulary. Always consult your plan documents or their member services line to confirm coverage for your vaccine needs.
Special Notes on Coverage
- Part D coverage includes the vaccine product and the administration fee (the cost for the pharmacist or provider to give you the shot).
- Some specialized travel or occupational vaccines may not be covered; check with your plan and provider in advance.
- Vaccines for acute exposure (e.g., after animal bites or serious injuries) are typically under Part B.

How to Access Your Medicare Part D Vaccine Benefits
Getting your recommended vaccines is easier than ever, thanks to simplified billing and broader network coverage. Here’s how to make the most of your Medicare Part D vaccine coverage:
Step-by-Step: Getting Your No-Cost Vaccines
- Review Your Medicare Part D Plan:
- Access your plan’s “formulary” (list of covered drugs and vaccines) online or by calling member services.
- Be sure to identify which vaccines are available at no cost.
- Verify Network Providers:
- Get vaccinated at a pharmacy or provider in your plan’s network to avoid paying out-of-pocket.
- If unsure where to go, your pharmacist or plan can help. For a list of Medicare-accepting doctors, read our step-by-step guide.
- Bring Your Medicare Card and Plan ID:
- Always show your insurance cards (both Medicare and Part D) when getting vaccinated.
- If Vaccinated Outside the Network:
- You may need to pay upfront and file a claim for reimbursement using the CMS-1500 form.
- Claims usually require a detailed receipt; keep this for your records.
Tip: Log into your online Medicare account to track past vaccines and ensure you’re up-to-date with preventive care.
Vaccine Administration Fees & Billing
Medicare Part D covers both the vaccine administration fee and the dose itself. You should never receive a bill for these services from a network provider or pharmacy in 2024. If you do, contact your plan for assistance.

Recent Changes: The Inflation Reduction Act and No-Cost Vaccine Coverage
The Inflation Reduction Act Medicare vaccines provision is a major win for older adults and caregivers. Effective January 1, 2023, all ACIP-recommended adult vaccines covered under Part D became available at no cost-including dispensing and administration fees.
- Eliminated Copays and Deductibles: No more out-of-pocket expense for shingles, RSV, Tdap, and more.
- Expanded Access: Bring your Medicare Part D card to any in-network pharmacy or provider for no-cost vaccination.
- Inclusivity: Applies to all Part D plans across the United States.
This change closes a previous coverage gap that left many beneficiaries paying high prices for essential vaccines like Shingrix. Now, cost is no longer a deterrent to getting protected from serious illnesses.

Frequently Asked Questions About Medicare Vaccine Coverage
Does Medicare cover the RSV vaccine?
Yes! The RSV vaccine Medicare coverage is now at zero cost under Part D. The CDC recommends it for everyone over 75, and optionally for those 60-74. Without a Part D plan, it is not covered under Original Medicare. If you have questions on eligibility or providers, learn how to find a Medicare-accepting doctor here.
Is the shingles vaccine covered by Medicare?
Absolutely. Shingles vaccine Medicare coverage is now complete and free under all Part D plans. This was a major advancement under the Inflation Reduction Act. If you need advice on choosing a plan with comprehensive coverage, check our complete Medicare resource.
What if I don’t have Part D coverage?
If you only have Original Medicare (Parts A and B), your vaccine options are more limited. You’re restricted to what Part B covers (flu, COVID-19, pneumonia, sometimes hepatitis B, and acute-exposure vaccines). However, some clinics and health departments offer no-cost or low-cost options for uninsured or underinsured adults. For a full breakdown of the process to start or upgrade your coverage, visit our Medicare enrollment guide.
How do I know if a vaccine is covered by my Part D plan?
Consult your plan’s online formulary or call their customer support line. All vaccines approved or recommended by ACIP for adults must be covered under Medicare Part D, except those already covered by Part B. Confused by billings and medical costs? Our out-of-pocket Medicare cost explainer can help clarify terms.
What should I do if vaccinated outside the network?
If you receive a Part D vaccine outside of your plan’s network, you might need to pay for it yourself first. Afterward, file a claim with your insurer using the CMS-1500 form. Keep all documents and receipts until reimbursement is processed. To minimize paperwork and costs, always verify provider participation in advance. For guidance on network providers, read this how-to guide.
Are there vaccines Medicare doesn’t cover?
Nearly all ACIP recommended vaccines are covered between Part B and D, but certain specialized travel and occupational vaccines might not be. Always consult your doctor and your plan’s benefits summary before receiving a new or less-common vaccine. For other medical supplies coverage, such as diabetes tech, visit coverage information for glucose monitors in 2025.
What if I’m billed for a vaccine Medicare should cover?
If you properly receive a covered vaccine through your plan’s network, you shouldn’t be billed an administration or dispensing fee. If you are, call your Part D plan immediately for help. For plan assistance and understanding coverage details, refer to Medicare program basics and contact information.
Does Medicare Supplement (Medigap) help with vaccine costs?
Medicare Supplement (Medigap) plans do not pay for Part D-covered vaccines, but they may assist with coinsurance for Part B vaccines if applicable. For an updated guide on Medigap in 2025, visit Medicare Supplement Plan coverage details.
How can I keep my vaccine records up to date?
Track your vaccinations using your Medicare online portal, or ask your pharmacist and provider for updated immunization printouts. Staying organized ensures you don’t miss boosters or duplicate doses.
Remember, your healthcare provider is your best source of trusted advice. Keep them informed of all vaccines received and consult them regarding ACIP recommendations for your age, medical history, and travel plans.
