Fall is when most people think about a flu shot and stop there. But if you're on Medicare, this is also a reasonable time to check whether you're due for a shingles vaccine, an RSV vaccine, or a booster, because two vaccines that sound similarly routine can be billed in completely different ways.
The short version: Medicare Part B covers some vaccines directly, at no cost to you. Part D, your drug plan, covers the rest, also at no cost since a 2023 rule change, but only if the pharmacy or clinic bills it correctly. Getting the wrong vaccine billed to the wrong part is the most common way people end up with a surprise charge.

Part B: Flu, COVID, Pneumococcal, and Hepatitis B
These four vaccines are covered directly under Medicare Part B, with no copay, no deductible, and no coinsurance, as long as the provider accepts Medicare assignment. That covers your annual flu shot, the current COVID-19 vaccine, pneumococcal vaccines (which protect against a common cause of pneumonia), and hepatitis B vaccination if you're at increased risk.
Part B coverage doesn't depend on which drug plan you have, because it isn't billed through a Part D plan at all. That's also why these shots are usually the simplest to get: most pharmacies, clinics, and doctor's offices bill Part B automatically and correctly.

Part D: Shingles, RSV, and Other Recommended Vaccines
Shingles and RSV vaccines are billed through your Medicare Part D drug plan instead of Part B. Since January 2023, federal law requires Part D plans to cover every vaccine recommended by the CDC's Advisory Committee on Immunization Practices at zero cost, meaning no copay and no deductible, no matter which Part D plan you have.
The catch is administration. If a pharmacy bills these vaccines correctly through your Part D plan, you should walk out paying nothing. If a doctor's office gives the shot but doesn't have a way to bill Part D, you can end up with a bill that shouldn't exist. Asking the question before the shot, not after, avoids that entirely.

Name where you're getting it
Most retail pharmacies bill Part D routinely. If you're going through a doctor's office instead, it's worth confirming ahead of time.
Ask This One Question Before the Needle Goes In
Before you roll up your sleeve for Flu or COVID-19 at your pharmacy or clinic, ask directly: "Will this be billed to Medicare Part B or to my Part D plan, and will I owe anything?" A pharmacist or front desk staff member who does this daily should be able to answer immediately. Hesitation is a signal to double-check before you proceed.
If you do get an unexpected bill, don't assume it's correct. Call the pharmacy or provider first and ask them to rebill it correctly. If that doesn't resolve it, your Medicare plan's member services line can confirm what should have been charged. Prepare for a Medicare or Social Security Phone Call walks through how to make that call count.

Common questions
Does Medicare cover the flu shot?
Yes. The flu vaccine is covered under Medicare Part B at no cost, with no copay, deductible, or coinsurance, as long as your provider accepts Medicare assignment. It's billed directly through Part B rather than through a drug plan.
Does Medicare cover the shingles vaccine?
Yes, but it's billed through your Medicare Part D drug plan rather than Part B. Since January 2023, federal law requires all Part D plans to cover CDC-recommended vaccines like Shingrix at no cost, meaning no copay or deductible, regardless of which Part D plan you have.
Is the RSV vaccine covered by Medicare?
Yes. The RSV vaccine is covered under Medicare Part D at no cost for adults 75 and older, and for adults 60 to 74 who are at higher risk. As with shingles, it's billed through your drug plan, not Part B, so it's worth confirming the pharmacy bills it correctly.
Why did I get a bill for a vaccine I thought Medicare covered?
The most common cause is a vaccine getting billed to the wrong part of Medicare, often when a doctor's office administers a Part D vaccine like shingles or RSV without a way to bill your drug plan correctly. Call the provider first and ask them to rebill it. If that doesn't fix it, your Medicare plan's member services line can confirm what you actually owe.
