Yes, Medicare Part D typically covers the Zostavax vaccine, which is used to prevent shingles in adults. Medicare Part D is the prescription drug coverage part of Medicare, and it may cover the cost of the Zostavax vaccine when it is prescribed by a healthcare provider. It's important to note that coverage may vary depending on the specific Medicare Part D plan, so it's advisable to check with the individual plan or the vaccine provider to confirm coverage and any potential out-of-pocket costs. Additionally, Medicare Part B may also cover the Zostavax vaccine if it is administered in a doctor's office or pharmacy that accepts Medicare assignment. As always, it's recommended to verify coverage details with the Medicare plan provider or healthcare professional for specific and up-to-date information.
