Drug Plans

Medicare Part D

Medicare Part D has distinct coverage phases that determine how much you pay for your medications throughout the year.

  • Deductible Phase:

    • Some Part D plans have a yearly deductible. This is the amount you must pay out-of-pocket for your prescriptions before your Medicare Prescription Drug Plan begins to pay its share.
    • Not all plans have a deductible, and for plans that do, not all drugs may be subject to the deductible.
    • No Medicare drug plan may have a deductible more than $615 in 2026.

  • Initial Coverage Phase:

    • After meeting the deductible (if your plan has one), you enter this phase.
    • During this phase, you pay a copayment (a fixed amount) or coinsurance (a percentage of the drug’s cost) for each covered drug.
    • Your plan pays the rest of the cost.
    • You remain in this phase until your total drug costs (what both you and the plan have paid) reach a certain amount for the year.
    • After you reach your full deductible (if your plan has a deductible), you’ll pay 25% of the cost as coinsurance for your generic and brand-name drugs until your out-of-pocket spending on covered Part D drugs reaches $2,000 in 2026 (including certain payments made on your behalf, like through the Extra Help program). Then, you’ll automatically get “catastrophic coverage.”

  • Catastrophic Coverage Phase:

    • After you’ve spent a certain out-of-pocket amount on drugs for the year, you enter the catastrophic coverage phase.
    • In this phase, You won’t have to pay out-of-pocket for covered Part D drugs for the rest of the calendar year.

Every year, the exact dollar amounts associated with these phases may change. It’s essential for Medicare beneficiaries to review their Part D plan materials each year and be aware of any changes to understand their potential costs.

Key details about Medicare Part D:

  • Coverage: Medicare Part D provides coverage for prescription drugs. Each Part D plan has a specific list of covered drugs, called a formulary. The formulary may be divided into tiers, and drugs in each tier have a different cost.
  • Private Plans: Part D plans are offered by private insurance companies that are approved by Medicare. You can get Part D coverage through a stand-alone Prescription Drug Plan (PDP) or as part of a Medicare Advantage Plan that includes drug coverage (MA-PD).
  • Enrollment: Enrollment is not automatic. Beneficiaries need to choose and enroll in a Part D plan unless they have equivalent drug coverage from another source (like a current or former employer).
  • Costs: Beneficiaries usually pay a monthly premium for the Part D plan. Costs for Part D plans can vary based on the drugs used, the plan chosen, the pharmacy used, and the beneficiary’s income. Some people may qualify for Extra Help, a program to help pay for Part D costs based on financial need.
  • Late Enrollment Penalty: If a beneficiary doesn’t sign up for Part D when they’re first eligible and they don’t have other creditable prescription drug coverage, they may have to pay a late enrollment penalty for as long as they have Part D.
  • Annual Election Period: Similar to Medicare Advantage plans, there’s an annual election period (often referred to as “open enrollment”) during which beneficiaries can join, switch, or drop a Medicare drug plan.
  • Medication Therapy Management Program: If beneficiaries have multiple chronic conditions, take multiple Part D drugs, and meet certain other criteria, they might be automatically enrolled in a free Medication Therapy Management (MTM) program. This program helps beneficiaries and their doctors make sure the medications are working as intended and are safe.
  • Protection Against High Out-of-Pocket Costs: After beneficiaries reach a yearly out-of-pocket limit, they enter a phase called “catastrophic coverage,” where You won’t have to pay out-of-pocket for covered Part D drugs for the rest of the calendar year.

When considering a Medicare Part D plan, it’s important for beneficiaries to review the plan’s formulary to ensure that their medications are covered and to understand the associated costs.
