The Eversense CGM system doesn’t have a single published retail price, which makes answering this question frustrating. Senseonics, the company behind Eversense, has not disclosed exact out-of-pocket costs. What we do know is that the total expense depends on your insurance coverage, the sensor model you use, and whether you qualify for the company’s savings program. For commercially insured patients who use the Eversense Pass program, out-of-pocket costs can be as low as $99 per sensor.
What You’re Actually Paying For
Eversense works differently from other CGMs like Dexcom or Libre. Instead of sticking a disposable sensor to your skin every week or two, a doctor implants a small sensor under your skin in a brief in-office procedure. You then wear a removable smart transmitter on top of the insertion site. This means your costs include the sensor itself, the transmitter, and the insertion and removal procedures performed by a healthcare provider.
The current model, the Eversense E3, uses a sensor that lasts 180 days (six months). The newer Eversense 365, which received FDA clearance in September 2024, extends that to a full year. Per-day cost is expected to remain similar between the two models, meaning the 365-day version should reduce the number of office visits and procedures you need each year from two down to one.
Costs With Commercial Insurance
Most major commercial insurers cover Eversense, though the specifics vary by plan. Cigna, for example, considers the implantable sensor medically necessary for adults 18 and older with type 1 or type 2 diabetes who use insulin, whether through multiple daily injections, a long-acting basal insulin, or an insulin pump. Other large insurers have similar policies, but coverage can fall under either your medical benefit or your pharmacy benefit depending on your plan. Prior authorization is commonly required.
Your actual copay or coinsurance depends entirely on your specific plan design. This is where the Eversense Pass savings program becomes important. Through this program, commercially insured patients can get their first sensor and transmitter for $99, and a second sensor for another $99. For ongoing use, the program caps your annual out-of-pocket spending at $600 for sensors and transmitters. That works out to roughly $50 per month or less, which is competitive with what many people pay for Dexcom G7 or Libre sensors after insurance.
The Eversense Pass program is only available to people with commercial (private) insurance. If you’re on Medicare, Medicaid, or another government plan, you won’t qualify for this particular discount.
Medicare Coverage
Medicare does cover implantable CGMs like Eversense. To qualify, you need a diabetes diagnosis and must meet at least one of these conditions: you’re currently treated with insulin, or you have a documented history of problematic low blood sugar. That history means either repeated episodes where your glucose dropped below 54 mg/dL despite attempts to adjust your treatment, or at least one severe low blood sugar episode where you needed someone else’s help to recover.
Your prescribing doctor also needs to confirm you’ve been trained on how to use the system. Once you’re set up, Medicare requires a follow-up visit every six months, either in person or via telehealth, to document that you’re using the CGM and sticking with your diabetes management plan. This aligns neatly with the E3’s six-month sensor life, since you’d need an office visit for sensor replacement anyway.
Medicare doesn’t publish a fixed reimbursement rate for Eversense in its coverage policy. Your out-of-pocket share will depend on whether you have Original Medicare with a supplement, a Medicare Advantage plan, or other secondary coverage. Calling your plan directly with the billing code (HCPCS code G0564 for the implantable sensor system) is the most reliable way to get a specific dollar amount.
Without Insurance
Senseonics has not released an official cash-pay retail price for the Eversense E3. Without insurance, you’d be responsible for the full cost of the sensor hardware, the transmitter, and the medical procedure to insert and later remove the sensor. Estimates from patient communities and diabetes advocacy groups suggest the uninsured cost is significantly higher than disposable CGM systems, largely because of the procedural component. If you’re uninsured, contacting Senseonics directly or asking the prescribing clinic for a cost estimate before scheduling insertion is essential.
How Eversense Compares on Cost
On paper, an implantable sensor that lasts six months to a year should cost less over time than replacing a disposable sensor every 10 to 15 days. In practice, the savings depend heavily on your insurance. The insertion and removal procedures add a cost layer that Dexcom and Libre don’t have, but you also aren’t buying a new sensor and applicator every couple of weeks.
For commercially insured patients using the Eversense Pass program, the math often works out favorably. A $600 annual cap on sensor and transmitter costs is lower than what many people spend on a year of Dexcom G7 supplies after copays. But this doesn’t account for any copays or coinsurance on the office visits for insertion and removal, which your plan bills as a medical procedure.
The Eversense 365 could shift this calculation further in Eversense’s favor. One insertion per year instead of two cuts your procedure-related costs in half while maintaining the same daily sensor cost. For someone who values fewer device changes and fewer supply shipments, the total cost of ownership may end up comparable to or lower than other CGM options, especially once the 365-day sensor becomes widely available.
