Paying Cash for Prescriptions on Medicare: What TrumpRx, Discount Cards and Coupons Do (and Don't Do)

If you take prescription drugs, you've probably noticed that cash prices, discount cards, manufacturer coupons and newer options like TrumpRx can sometimes beat what you'd pay through insurance. That's genuinely useful information. But when you have Medicare, paying cash comes with trade-offs that don't show up at the pharmacy counter. Here's a plain-English look at how these tools work alongside Medicare Part D.

What TrumpRx actually is

According to the official 2027 Medicare & You handbook, TrumpRx (TrumpRx.gov) is a free website that connects people with special offers and the lowest cash prices for certain prescription drugs. You can't buy drugs directly from the site. Instead, it gives you digital or printable coupons you take to the pharmacy.

In a Special Advisory Bulletin issued January 27, 2026, the HHS Office of Inspector General (OIG) described TrumpRx as a platform connecting cash-paying patients with direct-to-consumer drug programs offered by manufacturers and other private companies. In other words, it's a storefront that points you to manufacturer cash-pay deals.

The catch: cash purchases don't count toward Part D

This is the single most important thing to understand. When you use TrumpRx or other discount cards instead of your Medicare coverage, the purchase isn't considered creditable coverage and doesn't count toward your Medicare deductible or out-of-pocket maximum.

The OIG said the same thing about manufacturer direct-to-consumer sales: when a Part D enrollee buys a drug through a manufacturer's program, no claim is submitted to any insurer, and the price paid doesn't count toward Part D true out-of-pocket costs or total Part D spending for any purpose.

Why does this matter? Starting in 2027, Part D has a $2,400 annual out-of-pocket cap (it's $2,100 in 2026). Once your out-of-pocket spending on covered drugs hits that ceiling, you pay nothing more for covered Part D drugs the rest of the year. If you pay cash outside your plan, those dollars don't move you toward that cap. For someone taking expensive medications, that can be a meaningful difference by December.

The same goes for your plan's deductible. In 2027, the most any Part D plan may charge as a deductible is $700. Cash purchases don't chip away at it.

The late enrollment penalty is still a risk

Some people think, "If cash prices are low enough, maybe I'll skip Part D." Be careful. Because TrumpRx and discount cards aren't creditable prescription drug coverage, using them instead of Medicare drug coverage doesn't protect you against the Part D late enrollment penalty. That penalty can apply if you enroll after your Initial Enrollment Period ends and there was a period of 63 or more days in a row when you didn't have Medicare drug coverage or other creditable prescription drug coverage. The penalty is calculated using a national base beneficiary premium — $41.33 in 2027 — and it generally sticks with you for as long as you have Part D.

Manufacturer copay coupons work differently

Traditional manufacturer copay coupons — the kind that lower your copay on an insurance-covered prescription — are a separate issue. In a September 2014 bulletin, OIG said coupons used for drugs paid for by Medicare Part D implicate the federal anti-kickback statute, and such coupons typically state they may not be used by people in federal health care programs. If you have Medicare, read the fine print.

The newer direct-to-consumer cash programs the OIG addressed in 2026 are different because no claim goes to any insurer. The OIG said these cash sales are low risk under the anti-kickback statute when, among other conditions, the drug isn't billed to a federal health care program, the person has a valid prescription from an independent prescriber, the drug is offered through the program for at least one full plan year, and controlled substances aren't included.

Other ways to save

Medicare.gov points to several options worth exploring alongside — not instead of — your Part D coverage:

• Pharmaceutical (patient) assistance programs. Many drug companies help people enrolled in Part D pay for their medications. Each company sets its own eligibility rules, so check the manufacturer's website for your specific drug.
• State pharmaceutical assistance. Some states offer help with drug costs; eligibility varies.
• Mail-order pharmacies. Your plan may offer lower prices through mail order on long-term medications.
• The Medicare Prescription Payment Plan. This lets you spread your out-of-pocket Part D costs across the calendar year in monthly payments rather than paying large amounts at the pharmacy.
• Comparing TrumpRx prices to your plan's price. Sometimes cash is cheaper; sometimes your plan is. Just remember the cash price won't count toward your cap.

When you can make changes

Annual Enrollment runs October 15 – December 7, 2026, with new choices taking effect January 1, 2027. That's the main window to join, switch or drop a Part D plan or Medicare Advantage plan.

If you have Medicaid or Extra Help, since 2025 you've had a monthly Special Enrollment Period to move to Original Medicare with a stand-alone Part D plan, or to switch stand-alone Part D plans. Full-benefit dual-eligible individuals can also join an integrated D-SNP in any month.

Original Medicare + Medigap vs. Medicare Advantage

Both paths include ways to get Part D (built in with most Medicare Advantage plans; added separately with Original Medicare). Each has trade-offs around provider networks, out-of-pocket structure, extra benefits and flexibility. Neither is universally better — it depends on your medications, providers and budget.

Cash tools like TrumpRx can be a smart supplement, but your Medicare drug coverage is still the foundation that protects you from large unexpected costs — and from a penalty later on.
