Tetanus protection fades over time. A booster helps protect against tetanus and diphtheria (and pertussis with Tdap).
Ask when your last tetanus shot was.
Consider Tdap if you’ll be around infants.

Medicare Coverage
Tdap/Td is generally covered under Medicare Part D as a preventive vaccine.
In some cases (injury/exposure), vaccine coverage rules can differ.
Shingles, RSV, and Tdap are commonly Part D vaccines.
Key takeaways
Booster timing matters.
Usually Part D.
Injury/exposure scenarios can be different.
Good to Know
Part B vs Part D Vaccine Coverage
Medicare vaccine coverage can fall under Part B or Part D, depending on the vaccine and the situation. In general, Part B covers certain preventive vaccines and vaccines tied to specific medical situations, while Part D (your drug plan, including many Medicare Advantage plans with drug coverage) covers most other adult vaccines. Where you get the vaccine (doctor’s office vs pharmacy) can also affect how it’s billed and what you pay.
Provider Accepts Assignment
In Original Medicare, “accepts assignment” means a provider agrees to Medicare’s approved amount as full payment (with you paying any required deductible/coinsurance). For many preventive services, using a provider who accepts assignment can help keep your costs lower and more predictable.
