Therapeutic CGM Coverage at a Glance
|Therapeutic CGM Coverage
|Part A (Inpatient)
|Part B (Outpatient)
|Covers 80% of therapeutic continuous glucose monitor and associated supply costs once you meet your Part B deductible.
|Part C (Medicare Advantage)

Medicare Coverage for Therapeutic CGM
Medicare Part B covers therapeutic continuous glucose monitors (CGM) such as the FreeStyle Libre 2 and the Dexcom G6 for people with diabetes.
Medicare covers therapeutic continuous glucose monitors as durable medical equipment (DME). You will be responsible for your Medicare Part B deductible and 20% of the Medicare-approved cost. Medicare will cover the other 80% after you meet your deductible.
A Medigap policy — also called Medicare Supplement insurance — can cover some of your out-of-pocket costs for the Medicare Part B deductible and coinsurance. Additionally, Medicare Advantage plans are required to cover everything included in Medicare Part A and B coverage but may offer additional benefits.
Both Medigap and Medicare Advantage plans are sold by private insurers. Your plan’s administrator can verify your policy’s coverage of therapeutic CGM.
Medicare Eligibility for a Therapeutic CGM
A therapeutic CGM is a medical device approved by the U.S. Food and Drug Administration as a replacement for home blood sugar monitors. It provides you and your doctor with the medically necessary information to make diabetes treatment decisions, such as changes in diet and your insulin dosage.
To qualify for a therapeutic CGM, you must be undergoing treatment for diabetes and meet certain other criteria.
- You are using insulin to treat Type 1 or Type 2 diabetes.
- You need to check your blood sugar four or more times per day.
- You must use an insulin pump or receive three or more insulin injections per day.
- You must make routine, in-person visits to your doctor.
- Your doctor has determined that you meet all Medicare eligibility requirements.
The decision between a therapeutic CGM or a traditional monitor is one you should make after talking to your doctor. A therapeutic CGM may be a better option if you use insulin and frequently change your dosage.
Medicare Coverage of Therapeutic CGM Supplies
Medicare Part B medical insurance covers maintenance supplies for durable medical equipment — such as a therapeutic CGM — that ensure the equipment works properly.
- Test strips
- Lancing devices
- Glucose control solutions
- Other related supplies necessary for the proper operation of the therapeutic CGM
Medicare Part B may limit how often or how many supplies you can buy at one time. For example, insulin users are able to get up to 100 test strips and lancets per month. Patients who don’t use insulin are limited to roughly a third of that amount.
Medicare does not cover some diabetes supplies, such as syringes, needles and alcohol swabs.
