How do I compare Medicare Part D plans?
Enter your ZIP code above to see the stand-alone Medicare Part D prescription drug plans available where you live. Each plan has its own formulary, or list of covered drugs, and its own pharmacy network. A plan that works well for one person may cost much more for someone who takes different medications or uses a different pharmacy.
What is the best Medicare Part D plan?
There is no single best Part D plan. The best fit depends on your prescriptions, dosage, and pharmacy. Compare each plan using your current medication list and preferred pharmacy.
Is the Part D plan with the lowest premium the cheapest?
Not always. A lower-premium plan can have a higher deductible or charge more for your prescriptions. Compare the estimated total yearly cost, including premiums and drug costs.

Why do my pharmacy and drug list matter?
Part D plans have different formularies and pharmacy networks. Your copay can change based on whether a drug is covered, its tier, and whether your pharmacy is preferred by the plan.
