True or False: Medicare Part B and D have to pay a monthly premium.

The assertion that Medicare Part B and D require a monthly premium is indeed true. Medicare Part B, which covers outpatient services, preventative care, and more, has a monthly premium that beneficiaries must pay to maintain their coverage. This premium can vary based on income; however, all beneficiaries are generally required to pay some form of monthly premium.

Medicare Part D, which provides prescription drug coverage, also mandates a monthly premium. Like Part B, the amount may fluctuate based on the specific drug plan selected and the beneficiary's income level, but there is a basic expectation that enrollees will pay a premium for their coverage under Part D.

Both parts of Medicare ensure beneficiaries have access to necessary healthcare services, which is a critical component of the program’s design to help older adults manage their health needs effectively. Therefore, it is accurate to say that Medicare Part B and D necessitate a monthly premium.
