Important factors to compare
Formulary
Each plan has its own list of covered drugs. Confirm that your specific medications are included and at what tier.
Tiers and costs
Drugs are grouped into tiers, with different copay or coinsurance amounts. Lower tiers typically cost less.
Preferred pharmacies
Some plans offer lower costs at preferred or mail-order pharmacies. Check whether your pharmacy is included.
Coverage stages
Part D has several coverage stages, including deductible, initial coverage, and a gap. Understanding these helps you anticipate costs.
Enrollment periods
Reviewing your drug coverage annually during the Open Enrollment Period helps ensure your plan still fits your needs.
Common questions
Do I need Medicare Part D if I don’t take many medications?
Even if you take few medications now, enrolling when first eligible can help you avoid a late enrollment penalty if your needs change later. Your situation and available coverage should guide this decision.
Will my medication be covered?
Coverage depends on the plan’s formulary. Reviewing the formulary before enrolling helps you confirm your medications are listed and understand the costs.
Can I change my Part D plan later?
You can review and change your Part D coverage during the Annual Election Period each year, and during certain Special Enrollment Periods if you qualify.
