Medicare Part D prescription drug plans in Chadds Ford, PA
Part D plans add prescription coverage to Original Medicare. We help people in Chadds Ford and across Delaware and Chester Counties choose a plan based on the medications they actually take and the pharmacies they use.
How Part D works
Original Medicare doesn't cover most prescriptions you fill at a pharmacy. Part D plans, offered by private insurance companies approved by Medicare, fill that gap. If you have Original Medicare, with or without a Medigap policy, you'd add a stand-alone Part D plan. Most Medicare Advantage plans already include drug coverage.
Each plan has a list of covered drugs, called a formulary, organized into tiers. Generic drugs usually sit on lower tiers with lower copays. Your costs also depend on the plan's premium and deductible and on whether you use a preferred pharmacy or mail order.
Since 2025, Part D has a yearly cap on what you pay out of pocket for covered drugs. Once you reach it, you pay nothing more for covered prescriptions that year. The cap was $2,000 in 2025 and is adjusted each year. You can also choose to spread your drug costs into monthly payments.

Where drug coverage comes from
How you get Part D depends on which Medicare path you choose.
| Your Medicare coverage | How you get drug coverage |
|---|---|
| Original Medicare only | Add a stand-alone Part D plan. |
| Original Medicare and Medigap | Add a stand-alone Part D plan. Medigap plans sold today don't cover prescriptions. |
| Medicare Advantage | Usually included in the plan. You generally can't add a separate Part D plan to an Advantage plan that already includes drug coverage. |
| Employer or retiree coverage | May count as creditable coverage. Check before you decide to skip Part D. |
Avoiding the late enrollment penalty
If you go 63 days or more in a row without Part D or other creditable drug coverage after your Initial Enrollment Period, you may owe a penalty added to your premium for as long as you have Part D.
How to avoid it
- Join a Part D plan when you first become eligible, even if you take few medications.
- If you have employer or retiree coverage, keep the yearly notice that says whether it's creditable.
- Review your plan each fall so it keeps fitting your prescriptions.
Help paying for prescriptions
- Extra Help is a federal program that lowers Part D costs for people with limited income and resources.
- Pennsylvania residents 65 and older may qualify for PACE or PACENET, the state's prescription assistance programs.
- We can point you to the right application if it looks like you qualify.
Part D questions
Do I need Part D if I don't take many prescriptions?
It's usually still worth enrolling when you're first eligible. Joining later without other creditable coverage can mean a lifelong late enrollment penalty, and a low-premium plan can protect you if your needs change.
Can I change my Part D plan every year?
Yes. You can switch plans during the Annual Enrollment Period from October 15 to December 7. Plans change their formularies and costs each year, so a yearly review is a good idea.
What if my drug isn't on the plan's formulary?
You can ask the plan for an exception, switch to a covered alternative with your doctor's help, or choose a different plan during enrollment. Checking your drug list before you enroll avoids most surprises.
Is there still a donut hole?
No. The coverage gap was eliminated in 2025, and Part D now has a yearly cap on out-of-pocket costs for covered drugs.
Does Medicare Advantage include Part D?
Most Medicare Advantage plans include drug coverage. If yours does, you don't need a separate Part D plan.
