Medicare Part B covers the Tdap vaccine at no cost to you

Yes. Medicare Part B covers the Tdap vaccine (tetanus, diphtheria, and pertussis) with no copay, coinsurance, or deductible when you receive it from an in-network provider. You pay nothing out of pocket for the shot itself.

Tdap protects against three serious bacterial infections. Tetanus causes severe muscle stiffness and can be fatal. Diphtheria damages the heart and nerves. Pertussis (whooping cough) causes prolonged coughing that can lead to pneumonia, especially in older adults. A single Tdap dose provides protection, though your doctor may recommend a booster depending on when you last received one.

Medicare covers this vaccine because the Centers for Disease Control and Prevention (CDC) recommends it for all adults, including those 65 and older. Coverage applies whether you get the shot at your doctor's office, a pharmacy, or a health clinic.

Key Takeaways

  • Medicare Part B covers Tdap with zero cost to you when given by an in-network provider.
  • You do not need a referral or prior authorization to receive the Tdap vaccine under Medicare.
  • The vaccine is covered at doctor's offices, pharmacies, and clinics that accept Medicare.
  • If you received Tdap before age 65, your doctor will tell you whether you need a booster dose.
  • Out-of-network providers may charge you, so confirm your provider accepts Medicare before your appointment.

Where to get Tdap under Medicare

You can receive Tdap at several types of locations. Your primary care doctor's office is one option—call ahead to confirm they stock the vaccine and that it is covered under your plan. Many pharmacies, including those inside grocery stores and drugstores, administer Tdap and accept Medicare. Federally may have access to health centers and public health clinics also offer the vaccine.

Before you go, ask whether the provider is in-network for your specific Medicare plan. Original Medicare (Part A and Part B) has a different network than Medicare Advantage plans. If you have a Medicare Advantage plan, check your plan's provider directory or call the plan to confirm the location is in-network. Using an out-of-network provider may result in a bill to you.

What happens during your visit

When you arrive, bring your Medicare card. The provider will ask about your vaccination history—specifically, when you last received Tdap or a tetanus booster. This information helps them decide whether you need the vaccine now or can wait.

The shot itself takes seconds. Some people experience mild soreness at the injection site or low-grade fever for a day or two afterward. These reactions are normal and not dangerous. Serious side effects are rare. If you have concerns about whether Tdap is right for you—for example, if you have had a severe allergic reaction to any vaccine component in the past—discuss this with your doctor before your appointment.

Tdap boosters and timing

If you received Tdap as an adult before turning 65, you likely do not need another dose unless you have a specific reason. The CDC recommends a single Tdap dose for all adults who have not previously received one. After that, you need a tetanus booster (Td, not Tdap) every 10 years.

However, certain situations call for an earlier booster. If you have a deep or dirty wound and cannot remember when you last had a tetanus shot, your doctor may recommend one. If you are in close contact with an infant under 12 months old, a booster protects the baby from pertussis. Your doctor can review your vaccination record and advise you on timing.

Medicare Advantage and Tdap coverage

If you have a Medicare Advantage plan (Part C), Tdap coverage works the same way—the vaccine is covered at no cost when you use an in-network provider. However, each Medicare Advantage plan sets its own network, so the pharmacies and clinics available to you may differ from those in Original Medicare.

Contact your Medicare Advantage plan directly to find in-network locations near you that offer Tdap. You can also check your plan's website or member handbook. Using an out-of-network provider without prior authorization may result in you paying the full cost of the vaccine.

What to ask your doctor

Before your appointment, consider asking these questions:

  • Do I need Tdap, or have I already received it as an adult?
  • When was my last tetanus or Tdap shot?
  • Are there any reasons I should not receive this vaccine?
  • What mild side effects should I expect, and when should I call if something concerns me?
  • Is this provider in-network for my Medicare plan?
