Yes, Medicare does cover the Tdap vaccine. Medicare Part D, which is the prescription drug coverage, typically covers vaccines that are recommended by the Centers for Disease Control and Prevention (CDC) to prevent illness. The Tdap vaccine is one of the vaccines recommended by the CDC, so it is likely covered by Medicare Part D. However, it's important to note that coverage may vary depending on the specific Medicare plan you have. Some Medicare Advantage plans may also cover the Tdap vaccine. To get the most accurate information about coverage, it's best to contact your Medicare plan directly. They can provide you with specific details about coverage, including any copayments or deductibles that may apply. It's always a good idea to check with your healthcare provider and Medicare plan to confirm coverage before getting any vaccines. They can help you understand your specific coverage and any potential out-of-pocket costs.
