Yes, Medicare Part D and Medicare Advantage plans typically cover the Tdap vaccine. Medicare Part D provides prescription drug coverage, and Tdap is considered a prescription drug. Medicare Advantage plans, which are offered by private insurance companies approved by Medicare, also cover Tdap vaccine. However, coverage may vary depending on the specific plan, so it's important to check with the individual plan to confirm coverage details. Additionally, Medicare Part B may also cover the Tdap vaccine if it is deemed medically necessary. It's recommended to consult with a healthcare provider or the Medicare plan provider for specific coverage information.
