Medicare Part D plans provide prescription drug coverage to help reduce the cost of medications for individuals with Medicare. These plans are offered by private insurance companies approved by Medicare and can be added to Original Medicare or certain Medicare Cost Plans, Medicare Private Fee-for-Service Plans, and Medical Savings Account Plans. Each Part D plan has its own list of covered drugs (formulary), which may vary by provider, and may include different tiers that affect your out-of-pocket costs. While premiums, deductibles, and copayments can vary, enrolling in a Part D plan can offer significant savings and ensure access to the medications you need. It’s important to review each plan carefully to make sure it covers your prescriptions and works with your budget.
