Medicare Part A only covers drugs used as part of hospital inpatient treatment, and Medicare Part B only covers limited drugs such as vaccinations and drugs prescribed in hospital outpatient situations, according to Medicare.gov. Other prescription drugs are covered by Medicare Part D prescription drug plans. Although individuals may not need prescriptions drugs when enrolling in Medicare at age 65, Medicare Part D plans offer insurance protection for the future when needed prescription drugs may get expensive, advises AARP.
Since Medicare Part D plans are optional insurance provided by private companies, they involve payment of additional monthly premiums apart from monthly Medicare Part B premiums, states Medicare.gov. Other costs include yearly deductibles, copayments and coinsurance. Once drug costs go beyond a certain amount, participants reach a coverage gap known as the doughnut hole during which patients pay a higher percentage of costs for needed drugs. Additionally, patients must use drugs in the Medicare Part D plan formulary and pharmacies in the plan network, or the plan does not cover prescription drug costs. If Medicare recipients do not sign up for a Part D prescription drug plan when they first become eligible, they must pay a permanent monthly penalty for late sign-up.Learn more about Health Insurance
