If you have diabetes and you are using a continuous glucose monitor (CGM) it is likely either the Dexcom G6/G7 or the FreeStyle Libre 2 Plus / Libre 3 Plus. We speak to patients everyday that are struggling with how expensive it can be at the pharmacy. We hear stories of patients that are spending out-of-pocket costs that exceed their budget and are becoming unaffordable.
So they do what thousands of other patients do every month, they go to Google and type:
- Dexcom coupon
- FreeStyle Libre coupon
- cheap CGM
This is where we at Medically Modern tries to find the patient to educate them on what is really happening. Most patients believe they have to get their CGM from the pharmacy. Why wouldn’t they think this? Your doctor sends all other medications to the pharmacy. Why wouldn’t they also send the CGM? Unfortunately, when sending the CGM to their pharmacy it often comes with a high co-pay. As a natural next step, the patient searches online like dexcom coupons for a way to lower that price – usually through GoodRx or manufacturer coupons. They believe that coupons are the lowest price available.
Before patients find our page, they do not realize that their Freestyle Libre / Dexcom can also be covered under their medical benefits. What they don’t realize is that even with a coupon through the pharmacy, they are still overpaying. Many are stretching their budgets to keep their monitor running, paying money they don’t really have – when in reality, they could be getting the exact same device through their medical benefits for close to or many times at $0 altogether.

The Hidden Truth: One Device, Two Benefit Buckets
Here’s what makes Dexcom and FreeStyle Libre different from most prescriptions: they are one of the few products that fall under both your pharmacy benefits and your medical benefits.
- Pharmacy benefits (Part D): If you get your CGM from a retail (or mail order) pharmacy like CVS or Walgreens, it will run under your pharmacy benefits. That means high co-pays, deductibles, and limited coverage like you may be experiencing now.
- Medical benefits (Part B): If you get your CGM through a Durable Medical Equipment (DME) supplier like Medically Modern, it will run under your medical benefits. That usually means lower co-insurances, and many times, $0 out-of-pocket altogether.
Same device. Same insurance card. Two completely different outcomes dependent on where you get your Dexcom / Freestyle Libre from.
Why the Pharmacy Route Costs More?
When billed under pharmacy benefits (Part D), your CGM is treated like a prescription drug. That typically means:
- High monthly co-pays.
- Deductibles you must meet before coverage kicks in.
- Coupons that only shave off a small portion of the cost.
Even with discounts, most patients are still paying too much.
Why the DME Route Saves You Money
When billed under medical benefits (Part B) through a DME supplier like Medically Modern, your CGM is treated as medical equipment. That typically means: Lower or $0 out-of-pocket.
If you have any of the following you should be paying $0 out-of-pocket:
- Original Medicare A & B + Medicare Supplement (Secondary)
- United Medicare Advantage
- A Medicare Advantage Plan + Medicaid as a secondary
For many patients, the difference between paying $100+ per month at the pharmacy and paying $0 through their medical benefits is life-changing.
Real Google Reviews (51 Five-Star Reviews and Counting)
Don’t just take our word for it. Patients are leaving us five-star reviews every week:
⭐ Ron Street (Local Guide)
“Medically Modern went above and beyond to get me what I needed at no cost to me when the pharmacy locally was charging me $110 a month for the same item.”
⭐ Jana Townsend
“Medically Modern helped me get my Libre 3 monitor for free, due to my health care needs.”
⭐ Felicia Royster-Brown
“I was prescribed Dexcom G7 and when I filled my prescription I was charged $425. I applied for patient assistance. Now I am going to receive it for free! I am so thankful.”
Why Coupons Aren’t the Answer?
Let’s be clear:
- Searching for Coupons like “freestyle libre coupon 2025” are temporary. They might lower the cost slightly for a few months.
- Coupons are often only for cash-pay customers, not patients using insurance.
- Coupons don’t change your benefits. You’re still being billed under pharmacy benefits, which is why costs stay high.
The real solution isn’t chasing coupons. It’s making sure your Dexcom or FreeStyle Libre runs through the right benefit — your medical benefits (Part B) via a Durable Medical Equipment supplier.
