If you’ve been putting off a shingles shot or an RSV vaccine because you assumed it would cost you, here’s some good news: as of 2026, Medicare covers the full list of ACIP-recommended adult vaccines with a $0 copay. No deductible, no coinsurance, no “20% of the cost” surprise on your next statement. The catch is that which Medicare part pays — Part B or Part D — changes where you need to go to get the shot for free, and mixing that up is exactly how people end up with an unexpected bill.

Here’s a plain-English breakdown of which vaccines are free, which part of Medicare covers each one, and the steps to make sure you’re never billed for a vaccine you’re entitled to get at no cost.

1. Why Vaccines Are Now Free Under Medicare

A federal law change eliminated cost-sharing — copays, deductibles, and coinsurance — for all vaccines recommended by the Advisory Committee on Immunization Practices (ACIP). That protection now applies no matter how you get your Medicare coverage:

• Original Medicare (Part B)
• Standalone Part D prescription drug plans
• Medicare Advantage plans (which must match or beat Original Medicare’s coverage)

According to NCOA, a large share of older adults still don’t realize this rule applies to them and skip recommended vaccines simply because they expect to be charged. That gap matters — shingles alone sends tens of thousands of older adults to the hospital every year, and RSV can be serious for anyone over 60 with a chronic health condition.

2. Vaccines Covered Under Medicare Part B (No Copay)

These vaccines are billed directly through Medicare Part B, meaning you generally don’t need a separate drug plan to get them for free:

• Flu shot — the seasonal vaccine, updated with a new formula every year (see medicare.gov/coverage/flu-shots)
• COVID-19 vaccine — current 2025-2026 formula (see medicare.gov/coverage/covid-19)
• Pneumococcal (pneumonia) vaccine — protects against pneumococcal disease and pneumonia (see medicare.gov/coverage/pneumococcal-shots)
• Hepatitis B vaccine — for people at medium or high risk (including those with diabetes) (see medicare.gov/coverage/hepatitis-b-shots)

You can get any of these at a doctor’s office, an urgent care clinic, or a pharmacy — as long as the provider bills Medicare Part B directly, which most major pharmacy chains do automatically when you show your red, white, and blue Medicare card.

3. Vaccines Covered Under Medicare Part D (No Copay)

These vaccines are paid through your Part D prescription drug plan or the drug portion of your Medicare Advantage plan — not Part B. This is the single biggest source of confusion, because the vaccine itself is still $0, but only if the pharmacy is in your specific plan’s network.

• Shingles vaccine (Shingrix) — a two-dose series recommended for adults 50 and older (see medicare.gov/coverage/shingles-shots)
• RSV vaccine — recommended for adults 60+ at higher risk, and generally advised for everyone 75 and older (see medicare.gov/coverage/rsv-vaccines)
• Tdap — tetanus, diphtheria, and whooping cough (pertussis) booster
• Other ACIP-recommended adult vaccines not billed under Part B

This is the #1 reason people get billed by mistake: the vaccine is free, but only at a pharmacy that’s in-network for your particular Part D or Medicare Advantage drug plan. Walk into an out-of-network pharmacy and you can be charged the full retail price upfront — often $200 or more for Shingrix — even though the exact same shot would have been $0 next door.

4. Medicare Advantage: What’s Different

If you have a Medicare Advantage plan, the same $0 copay rule applies — federal law requires Advantage plans to cover these vaccines at least as generously as Original Medicare. What changes is the network. Advantage plans often have narrower pharmacy and provider networks than a standalone Part D plan, so a pharmacy that’s in-network for your neighbor’s plan may not be in-network for yours.

Before you go in for a shot, log into your plan’s member portal or call the number on the back of your Advantage card to confirm the specific pharmacy or clinic is in-network for vaccines under your plan.

5. A Simple Decision Checklist Before You Get Any Vaccine

Use this quick checklist to figure out what to confirm before you roll up your sleeve:

• Getting a flu, COVID-19, pneumococcal, or hepatitis B shot? → This is billed under Part B. Any provider or pharmacy that accepts Medicare and bills Part B directly should charge you $0. Just show your Medicare card.
• Getting a shingles, RSV, or Tdap shot? → This is billed under Part D. Call ahead and ask the pharmacy: “Are you in-network for vaccines under my specific Part D or Medicare Advantage plan?” Have your plan name and member ID ready.
• Not sure which part covers your vaccine? → Check the specific medicare.gov/coverage page for that vaccine, or call 1-800-MEDICARE and ask directly before scheduling.
• Pharmacy says it will charge you upfront? → Don’t pay out of pocket if you believe the vaccine should be free. Ask them to bill Medicare directly first, or call your plan to find an in-network location nearby.

6. How to Avoid a Surprise Bill

Three habits prevent almost every accidental vaccine bill:

1. Confirm the Medicare part first. Part B vaccines (flu, COVID-19, pneumococcal, hepatitis B) are billed through any Medicare-accepting provider. Part D vaccines (shingles, RSV, Tdap) require an in-network pharmacy for your specific drug plan.
2. Ask before you get the shot — not after. A quick phone call (“Will you bill Medicare directly for this vaccine, and is my plan in-network?”) takes two minutes and prevents a $200+ bill.
3. Keep your Medicare and drug plan cards handy. Pharmacies need both your Medicare number and your Part D/Advantage plan details to bill correctly the first time.

If you’re charged anyway, don’t assume you’re stuck with the bill. Contact your Part D or Medicare Advantage plan’s member services line, explain that the vaccine should have been covered at $0, and ask about their reimbursement or claims process. Keep your receipt — you’ll likely need to submit it along with a claim form. If the plan denies the claim and you believe the vaccine was ACIP-recommended, you can also file an appeal through your plan or call 1-800-MEDICARE for help.

FAQ

Do I need a referral to get a covered vaccine?
No. You can walk into a participating pharmacy, doctor’s office, or urgent care clinic and request any of these vaccines directly — no referral is required.

Are travel vaccines covered?
Generally, no. Vaccines required only for international travel (such as yellow fever) are typically not covered by Medicare unless they also fall under the ACIP adult immunization schedule for domestic use.

Does Medicaid also cover these vaccines for dual-eligible beneficiaries?
Yes. If you’re enrolled in both Medicare and Medicaid, Medicaid is also required to cover ACIP-recommended adult vaccines with no cost-sharing, so dual-eligible beneficiaries should not be charged either.

What if my pharmacy says a vaccine isn’t covered — who do I call?
Call the member services number on your Part D or Medicare Advantage card first to confirm network status. If you still believe you were wrongly charged, call 1-800-MEDICARE (1-800-633-4227) for help resolving the issue.
