Who qualifies?
Medicare covers this when your records show all of the following. Your prescriber's documentation is what establishes each point:
- You have diabetes.
- Your treating provider has ordered a CGM for you.
- You either use insulin, or have a documented history of problematic (recurrent, severe) low blood sugar.
- You've had (or will have) a visit with your provider about your diabetes within 6 months of the order.
- You've received training on using the device.
Not sure if you qualify?
Check your Medicare coverage in one step, or talk to an intake specialist. We verify your benefits and coordinate the order with your prescriber — no cost or commitment to check.
What Medicare covers
- The CGM device and its supplies (sensors, transmitter) under Part B as durable medical equipment.
- Medicare Part B generally pays 80% of the Medicare-approved amount after you meet the annual Part B deductible; the remaining share is your responsibility (or a secondary plan's, such as Medicaid or a supplement).
- Coverage is billed to Medicare by an enrolled DMEPOS supplier — like us.
Coverage details and amounts are set by CMS and can change each year. We confirm your current, specific coverage before anything is ordered.
