What costs can Mr. Alonso expect when enrolling in a standard Medicare Part D prescription drug plan?

Enrolling in a standard Medicare Part D prescription drug plan typically involves several associated costs that beneficiaries should be aware of. The correct choice highlights the standard cost structure, which includes a monthly premium that individuals must pay for their drug coverage. This premium varies by plan but is a common feature of Part D plans.

In addition to the monthly premium, beneficiaries might encounter an annual deductible. This is the amount that individuals must pay out-of-pocket for their prescriptions before the insurance plan begins to help cover costs. After meeting the deductible, beneficiaries generally pay a per-prescription cost-sharing amount, which can take the form of co-payments or co-insurance depending on the specific medications and their classifications within the plan's formulary.

Understanding this cost structure is crucial for beneficiaries like Mr. Alonso, as it helps in budgeting for healthcare expenses under Medicare Part D. The other options listed do not accurately reflect the comprehensive nature of costs associated with a standard Part D plan.
