Short answer
Covered: Part B
Yes, Medicare Part B covers a continuous glucose monitor and related supplies, like sensors, as durable medical equipment if you have diabetes, your doctor orders them and you meet Medicare's conditions.
To qualify for a continuous glucose monitor under Medicare Part B, you must take insulin or have a history of problems with low blood sugar (hypoglycemia), and you or your caregiver must have had enough training to use the monitor as directed.
With Medicare Part B in 2026, you pay 20% of the Medicare-approved amount for a continuous glucose monitor after the $283 Part B deductible, if your supplier accepts assignment.

What does Medicare cover for continuous glucose monitors?
Medicare Part B covers a continuous glucose monitor and related supplies, like sensors, as durable medical equipment (DME) when you have diabetes and meet Medicare's conditions. A continuous glucose monitor tracks your glucose (blood sugar) levels through a device attached to your body.
Medicare covers different kinds of DME in different ways. Depending on the type of equipment, you may need to rent it, you may need to buy it, or you may be able to choose whether to rent or buy it. Some items become your property after you've made a certain number of rental payments.
Who qualifies for a continuous glucose monitor under Medicare?
Medicare Part B may cover a continuous glucose monitor if you have diabetes, your doctor or other health care provider orders it, and you meet both of these conditions:
- You take insulin or have a history of problems with low blood sugar (hypoglycemia).
- You or your caregiver have had enough training to use a continuous glucose monitor as directed.
What does my doctor have to do?
Your doctor or other health care provider must evaluate you and make sure you're eligible before ordering a continuous glucose monitor. Medicare's diabetes coverage booklet adds that if you use a continuous glucose monitor, you must make routine in-person or Medicare-approved telehealth visits with your doctor.
What do I pay for a continuous glucose monitor with Medicare?
After you meet the Part B deductible ($283 in 2026), you pay 20% of the Medicare-approved amount for a continuous glucose monitor and its supplies, if your supplier accepts assignment. A supplier that participates in Medicare must accept assignment, which means it can charge you only the coinsurance and Part B deductible on the Medicare-approved amount.
A supplier that doesn't participate in Medicare or won't accept assignment may charge you more. For rented equipment, make sure the supplier accepts assignment for all rental months; otherwise you'll have to pay the full cost upfront, and Medicare pays you back later for the amount it covers once your claims are processed.
Where do I get a Medicare-covered continuous glucose monitor?
Get your monitor and sensors from doctors and DME suppliers that are enrolled in Medicare, and ask the supplier whether it participates in Medicare or accepts assignment before you get the equipment. Medicare.gov has a search tool for medical equipment suppliers. Medicare won't pay for diabetes supplies you didn't ask for or that a supplier sent you automatically.
Does Medicare Advantage or Medigap change this?
Medicare Advantage plans must cover all medically necessary services that Original Medicare covers, but out-of-pocket costs vary by plan, and a plan may require you to use providers in its network or get approval (prior authorization) before it covers certain supplies. Contact your plan to find out how it covers diabetes supplies. See how Medicare Advantage differs from Original Medicare.
A Medigap (Medicare Supplement Insurance) policy helps pay your share of costs in Original Medicare, like coinsurance and deductibles, so it can help with the 20% you owe for a covered monitor.
