No. When you buy a prescription with a TrumpRx coupon or another discount card instead of using your Part D coverage, Medicare says that purchase doesn't count toward your Part D deductible or your yearly out-of-pocket maximum. Using a discount card also isn't creditable drug coverage, so it can't replace Part D or protect you from a late enrollment penalty.
Discount cards can save real money on a single prescription, and Medicare now points people to TrumpRx.gov so they can compare cash prices with their plan's price. The trap is what happens to the rest of your year. Here is how TrumpRx works, how cash purchases interact with Part D, and how to decide which way to pay at the pharmacy counter.
What is TrumpRx?
According to Medicare's 2027 update, Your Medicare in 2027: What's New & Changing, TrumpRx.gov is a free website that shows discounted cash prices and special offers for certain prescription drugs, so you can compare them with what your plan charges. A few details matter:
- You can't buy drugs through the site itself.
- It offers digital or printable coupons you take to a pharmacy.
- It covers certain drugs, not every prescription.
In other words, it works like other prescription discount cards: a coupon that lowers the cash price at the counter, separate from your insurance.
Does a TrumpRx or discount card purchase count toward my Part D deductible?
No. Medicare says using TrumpRx or other discount cards instead of Medicare or other coverage doesn't count toward your Part D deductible or out-of-pocket maximum. The pharmacy processes the sale as a cash purchase, so your Part D plan never sees it.
That has two practical effects:
- Your deductible doesn't shrink. If your plan has a deductible, a discount-card purchase leaves it untouched, so later prescriptions may still cost full price until you meet it through the plan.
- You move more slowly toward the yearly cap. Part D has an annual out-of-pocket maximum. After you reach it, you pay nothing for covered Part D drugs for the rest of the year. Cash purchases don't move you toward it. Our guide to the Part D out-of-pocket maximum for 2027 explains how the cap works.
Is a discount card the same as having Part D?
No, and this is the costlier mistake. Medicare says using TrumpRx or other discount cards doesn't count as creditable coverage. Creditable coverage is drug coverage that is expected to pay, on average, at least as much as Medicare's standard Part D coverage, such as many employer or union plans.
Why it matters: if you go without Part D or other creditable drug coverage for a stretch after you first become eligible, you can owe a Part D late enrollment penalty for as long as you have Part D. Relying on discount cards in place of a drug plan doesn't protect you from that penalty, even if your prescriptions are inexpensive today.
The same goes for people still working past their Initial Enrollment Period. If your employer drug coverage is creditable, your plan should tell you so each year in a creditable coverage notice. Keep those notices. A discount card in your wallet is not a substitute for that letter, and it won't count when Medicare looks back at whether you had coverage.
When does paying cash with a coupon make sense?
Sometimes it does. Here's a side-by-side to use at the pharmacy:
| Situation | Use your Part D plan | Use a TrumpRx or discount coupon |
|---|---|---|
| You expect high drug costs this year | Usually better: every covered purchase moves you toward the yearly cap | Saves on one fill but slows your progress toward the cap |
| The drug isn't on your plan's formulary | Plan may not pay; ask about an exception | Often worth comparing; the purchase won't count either way |
| Your plan's price for this drug is higher than the coupon price | Counts toward deductible and cap | Lower cost today; check whether the trade-off is worth it |
| You have no Part D or creditable coverage | Not available | Lowers cash price but doesn't count as coverage; late enrollment penalty risk |
| You get Extra Help | Extra Help lowers your plan costs | Rarely better; compare carefully |
The general rule: if you take several brand-name drugs or expect a big year, run purchases through your plan so they count. If you take one inexpensive generic and the coupon price is lower than your copay, a coupon may cost less for that fill. Ask the pharmacist to price it both ways.
How do I compare TrumpRx prices with my plan's price?
- Look up the drug on TrumpRx.gov and note the coupon price and pharmacy.
- Check your plan's price for the same drug, dose and quantity, using your plan's online tool or Medicare's plan finder.
- Check where you are in the year. Still in your deductible? Close to the out-of-pocket cap? That changes the math.
- Ask the pharmacist to run both before you pay. They can show the plan price and the coupon price at the counter.
- Keep your receipts. If you switch plans during Open Enrollment, a list of what you paid and where helps the comparison.

Does this work differently in North Carolina, South Carolina or Tennessee?
No. TrumpRx and the Part D rules are national, so the answer is the same in Charlotte, Rock Hill or Nashville. What varies locally is which pharmacies honor a given coupon and which pharmacies are preferred in your plan's network. If you live near the NC and SC line and use pharmacies in both states, check that your plan treats each one the way you expect before you rely on it.
