You’re standing at the pharmacy counter in Boca Raton.

Your pharmacist recommends a vaccine.

Before pulling out your wallet, there’s a simple Medicare question worth asking:

“Is this vaccine covered by my Medicare Part B or Part D?”

That distinction matters more than many Medicare beneficiaries realize.

Medicare Part B covers certain vaccines, while Medicare Part D covers other recommended adult vaccines. Under current Medicare rules, Part D adult vaccines recommended by the Advisory Committee on Immunization Practices (ACIP) are available without a deductible or cost sharing.

That means an eligible vaccine you assumed would cost $100, $200, or more could potentially cost you $0 out of pocket through your Part D coverage.

But there are still a few things worth checking before receiving the shot.

Let’s break it down.

---

First: Medicare Vaccines Can Fall Into Two Different Buckets

One reason Medicare vaccine coverage can be confusing is that vaccines aren’t all paid for through the same part of Medicare.

Some fall under Medicare Part B.

Others fall under Medicare Part D.

According to Medicare’s prescription drug and vaccine coverage guidance, Medicare Part B covers certain vaccines such as:

• Flu
• COVID-19
• Pneumococcal
• Hepatitis B in qualifying circumstances

Part D generally covers commercially available vaccines that aren’t covered under Part B when they’re medically necessary to prevent illness.

That includes vaccines for illnesses such as:

• Shingles
• RSV
• Tetanus
• Diphtheria
• Pertussis (whooping cough)

For Boca Raton Medicare beneficiaries, knowing which part of Medicare is responsible is the first step toward understanding how the vaccine should be billed.

---

The $0 Part D Vaccine Rule

This is the part many beneficiaries still don’t know about.

Federal law eliminated the Part D deductible and cost sharing for adult vaccines recommended by ACIP beginning in 2023.

CMS subsequently codified that requirement in its Medicare rules. CMS’s 2026 Medicare Advantage and Part D final-rule summary confirms that the Part D deductible doesn’t apply and beneficiaries have no cost sharing for qualifying ACIP-recommended adult vaccines covered under Part D.

In plain English:

If you have Medicare Part D and the qualifying adult vaccine is covered under Part D, you generally shouldn’t have a copay or deductible for it.

That’s a meaningful benefit.

Especially for vaccines that historically could have created substantial out-of-pocket expenses.

---

A Good Example: The Shingles Vaccine

Shingles is a perfect example of why understanding Part D vaccine coverage matters.

According to Medicare’s shingles vaccine coverage page, the shingles vaccine is covered through Medicare Part D, and beneficiaries with Part D pay nothing for the covered vaccine.

The CDC currently recommends two doses of the recombinant shingles vaccine for adults age 50 and older, as well as certain immunocompromised adults age 19 and older. CDC’s shingles vaccination recommendations provide additional guidance on who should receive the vaccine.

So if you’re 65, 70, 75, or older and have been putting off your shingles vaccination because you assumed it would be expensive, it’s worth checking your current Medicare drug coverage.

---

What About Tdap?

Tdap protects against:

• Tetanus
• Diphtheria
• Pertussis, also known as whooping cough

Medicare confirms that Tdap is covered through Medicare Part D and qualifying beneficiaries with Part D pay nothing for the vaccine.

Again, the important point isn’t simply that Medicare “covers vaccines.”

It’s knowing which part of Medicare pays for which vaccine.

---

And What About RSV?

RSV has become an increasingly important vaccine discussion for older adults.

Current CDC guidance recommends a single dose of RSV vaccine for:

• All adults age 75 and older
• Adults ages 50–74 who are at increased risk of severe RSV illness

The CDC notes that RSV vaccination isn’t currently an annual vaccination. Review the CDC’s current adult RSV vaccine guidance for the latest clinical recommendations.

Medicare Part D covers recommended RSV vaccination with no out-of-pocket cost when the applicable requirements are met.

If you’re unsure whether an RSV vaccination is appropriate for you, discuss your individual health situation with your doctor or pharmacist.

---

The Pharmacy Question Boca Raton Seniors Should Ask

Here’s where today’s guide becomes practical.

Before receiving a vaccine at the pharmacy, ask:

“Do you bill my Medicare plan for this vaccine, and are you in my plan’s pharmacy network?”

Why?

Because Medicare Part D plans contract with pharmacy networks.

According to Medicare’s pharmacy network guide, some Medicare plans require covered drugs to be obtained through in-network pharmacies.

Medicare also distinguishes between:

In-network pharmacies

and

Preferred in-network pharmacies.

Preferred pharmacies can sometimes provide lower out-of-pocket costs for ordinary prescriptions because of their agreements with the plan.

For qualifying $0 Part D vaccines, the vaccine itself doesn’t suddenly gain normal cost sharing simply because one preferred pharmacy is cheaper than another. But confirming that the pharmacy can properly process your plan’s vaccine benefit can help prevent billing headaches.

So before receiving the vaccine, ask the pharmacy to run your Medicare drug coverage first.

---

Don’t Automatically Pay Cash

Imagine this scenario.

You’re at a Boca Raton pharmacy and the cashier tells you:

“That’ll be $180.”

Your first reaction might be to simply pay.

Before doing that, ask a few questions.

Is the vaccine being billed through the correct part of Medicare?

Did the pharmacy process your Medicare drug plan?

Is this pharmacy participating with your plan?

Is the vaccine one of the ACIP-recommended adult vaccines covered under Part D without cost sharing?

A billing issue doesn’t necessarily mean the vaccine isn’t covered.

Sometimes the issue can be how or where the claim is being processed.

If something doesn’t look right, contact your Medicare drug plan before paying a large amount out of pocket.

---

Part B vs. Part D: A Simple Vaccine Cheat Sheet

Here’s an easier way to remember the distinction.

Often covered through Medicare Part B

Examples include:

Flu vaccine

COVID-19 vaccine

Pneumococcal vaccine

Certain hepatitis B vaccinations

Often covered through Medicare Part D

Examples include:

Shingles vaccine

RSV vaccine

Tdap vaccine

Other qualifying ACIP-recommended adult vaccines not covered by Part B

This isn’t a substitute for checking your individual coverage or discussing vaccinations with your healthcare provider.

But it gives you a much better starting point when speaking with your Boca Raton pharmacy.

---

Your Part D Plan Is About More Than Vaccines

The $0 vaccine benefit is valuable.

But it shouldn’t be the only thing you consider when comparing Medicare Part D plans.

Your prescription drug coverage should still be evaluated based on:

• Your current medications
• Drug formulary
• Drug tiers
• Monthly premium
• Deductible
• Copays and coinsurance
• Pharmacy network
• Preferred pharmacies
• Prior authorization requirements

Medicare explains that every Part D plan maintains a drug list called a formulary, and plans can organize covered medications into different cost-sharing tiers. Learn how Medicare Part D formularies work.

This is especially important if you take several maintenance medications.

A plan that works well for one Boca Raton resident’s prescriptions may be a poor fit for someone living next door.

---

2026 Has Another Important Part D Number: $2,100

Vaccines aren’t the only Part D cost protection worth knowing about.

For 2026, Medicare’s annual out-of-pocket threshold for covered Part D drugs is $2,100.

After your out-of-pocket spending on covered Part D drugs reaches that threshold—including certain payments made on your behalf—you enter catastrophic coverage and pay $0 for covered Part D drugs for the remainder of the year.

You can review the current numbers in Medicare’s 2026 Part D cost guide.

It’s another reason we encourage beneficiaries to evaluate their entire prescription picture, rather than looking only at monthly premiums.

Five Questions to Ask Your Boca Raton Pharmacist

Before receiving your next vaccine, consider asking:

1. Is this vaccine covered under Medicare Part B or Part D?

This determines how the vaccine should generally be billed.

2. Does my Medicare drug plan cover this vaccine?

For qualifying ACIP-recommended adult vaccines under Part D, federal rules provide $0 cost sharing.

3. Are you in my Medicare plan’s pharmacy network?

Confirm this before the vaccine is administered.

4. What should I owe today?

If you’re unexpectedly being asked to pay a large amount for a qualifying Part D vaccine, ask why.

5. Should I contact my Medicare plan before receiving it?

If the pharmacy can’t clearly explain the coverage or billing, calling the plan before paying may prevent unnecessary headaches.

---

What If the Pharmacy Says Your Vaccine Isn’t Covered?

Don’t immediately assume the answer is final.

Start by asking why.

It could be that:

• The vaccine falls under a different part of Medicare
• Your Medicare drug coverage wasn’t processed correctly
• The pharmacy isn’t participating with your plan
• The vaccine isn’t currently recommended for your situation
• Additional information is needed
• There’s a billing or claim-processing issue

You can contact the number on your Medicare drug plan identification card and ask the plan to explain the coverage.

If you need help understanding your Medicare coverage more broadly, call Medicare Plan Assistance at (561) 808-9410.

---

Don’t Forget to Ask Whether You Actually Need the Vaccine

Coverage is only one part of the conversation.

Whether a particular vaccine is medically appropriate for you is a healthcare decision.

Your physician or pharmacist can help you consider factors such as:

• Age
• Previous vaccinations
• Medical conditions
• Immune status
• Medication history
• Previous reactions
• Current CDC recommendations

Medicare coverage doesn’t mean every vaccine is appropriate for every beneficiary.

Use your healthcare provider for medical advice and your Medicare coverage information to understand the insurance side.

---

Final Thoughts: Ask Before You Pay

Here’s the most important thing to remember from today’s guide:

Don’t assume a vaccine will be expensive just because it used to be.

Current Medicare rules provide $0 cost sharing for qualifying ACIP-recommended adult vaccines covered under Part D.

Before receiving your vaccine:

Ask which part of Medicare covers it.

Confirm that your pharmacy can properly bill your plan.

Ask what you’ll owe before the vaccine is administered.

And if the answer doesn’t make sense, investigate before paying a large bill.

Sometimes one question at the pharmacy counter can save you a lot of confusion.
