Prescription medications can be some of the biggest costs you’ll face as a Medicare enrollee. Even if you aren’t currently taking any medications, you’ll likely need to at some point. So can GoodRx come in handy when you head to the pharmacy counter? Here’s a look at when you may want to consider using GoodRx savings instead of Medicare prescription coverage.
Medicare Part D plans cover prescription medications, vaccines, and certain medical supplies. Each Part D plan has a list of what it covers, also known as its formulary. Part D coverage is included in most Medicare Advantage plans. But people with original Medicare (Part A and/or Part B) have to buy a standalone Part D plan if they want prescription medication coverage.
Can you use GoodRx with Medicare?
No, you can’t use GoodRx savings with your Medicare coverage to pay for a prescription medication. You are allowed to have Medicare coverage but use a GoodRx discount instead. You may want to do this if the GoodRx price is lower than your Medicare Part D copay — especially if you don’t expect to reach your annual out-of-pocket maximum for covered medications.
Search and compare options
If you decide to use a GoodRx discount instead of your Medicare coverage, you will need to ask the pharmacist to run a cash transaction and not use your insurance. Make sure to present your GoodRx coupon before the pharmacist runs the transaction.
Since you will be paying cash, what you spend on the medication will not be applied toward your Part D out-of-pocket costs. Though, you can contact your Part D plan provider to find out if they are willing to credit the cash-pay price toward your deductible and out-of-pocket maximum.
When should you use GoodRx instead of Medicare?
You may want to use GoodRx savings instead of Medicare in certain situations. Here are some common ones:
Your prescription medication isn’t covered by Medicare. If this is the case, GoodRx may be able to help you pay less out of pocket for your prescription medication. GoodRx can also help you save on over-the-counter medications and vaccines.
The GoodRx price is lower than your Medicare copay. In some cases — but not all — applying a GoodRx discount may offer you a more affordable price than using your Medicare coverage.
You won’t reach your annual deductible. If you know you won’t meet your Medicare plan’s deductible for the year — which is up to $615 in 2026 for Part D — it might make sense to use GoodRx discounts. That’s because you don’t start sharing costs with your plan until you spend a certain amount on your own.
Are GoodRx cash prices always cheaper than Medicare copays?
While not always, GoodRx can offer the most affordable prices on many prescription medications. That’s why it’s smart to check the GoodRx price for your medication before going to the pharmacy — especially if you have a new prescription or your coverage has changed.
Can you use GoodRx coupons to cover Medicare out-of-pocket costs?
No, you cannot use GoodRx coupons to help with your out-of-pocket costs for covered prescriptions or services. And in most instances, what you pay when you’re not using Medicare coverage doesn’t count toward your deductible or out-of-pocket maximum.
If you want to try to reach your Part D annual out-of-pocket limit, you’ll generally need to use your insurance for covered prescriptions, so that your spending counts In 2026, the Part D out-of-pocket limit on covered medications is $2,100. If you spend this amount, your Medicare prescription plan will pay 100% of the costs of your covered medications for the rest of the year.
The bottom line
If you’re a Medicare enrollee, there may be times when it makes sense to use GoodRx savings instead of your Part D coverage. If Medicare doesn’t cover your medication, the GoodRx price is lower than your Medicare copay, or you don’t think you’ll meet your annual deductible, using a GoodRx discount may be the best option.
If you do use a GoodRx discount instead of your Medicare coverage, make sure the pharmacist knows in advance that you prefer a cash transaction and have a coupon to apply.
