Managing diabetes effectively requires continuous glucose monitoring (CGM) systems to track blood sugar levels in real time. Medicare recognizes the importance of CGM devices and offers coverage for specific diabetic sensors to eligible beneficiaries. In this guide, we’ll explore which diabetic sensors are covered by Medicare, who qualifies for them, and what costs you can expect.
What Diabetic Sensor Does Medicare Cover?
Medicare covers therapeutic continuous glucose monitoring (CGM) systems, which help individuals manage their diabetes without frequent fingersticks. The primary CGM systems covered under Medicare Part B include:
- FreeStyle Libre 2 and FreeStyle Libre 3 (manufactured by Abbott)
- Dexcom G7 and Dexcom G6 (manufactured by Dexcom)
These sensors continuously monitor glucose levels and send real-time data to a smartphone or reader. Medicare generally covers these CGMs for insulin-dependent diabetics who meet specific eligibility criteria.
Who Qualifies for FreeStyle Libre 2 Under Medicare?
To qualify for FreeStyle Libre 2 under Medicare, you must meet the following requirements:
✅ Have diabetes (Type 1 or Type 2)
✅ Use multiple daily insulin injections or require insulin pump therapy
✅ Have a physician’s prescription confirming medical necessity
✅ Conduct frequent blood glucose self-testing (typically four or more times per day)
✅ Attend regular follow-up visits with a healthcare provider
If you meet these conditions, Medicare Part B may cover FreeStyle Libre 2 and its associated supplies.
Does Medicare Cover the Dexcom G7 Sensor?
Yes! Medicare covers the Dexcom G7 sensor, as it is classified as a therapeutic CGM. Similar to the FreeStyle Libre system, the Dexcom G7 helps insulin-dependent individuals track their glucose levels accurately.
To qualify for Dexcom G7 under Medicare, you must:
✔ Be diagnosed with diabetes (Type 1 or Type 2)
✔ Use insulin multiple times daily
✔ Require frequent blood sugar monitoring
✔ Have a healthcare provider’s prescription
Medicare will cover Dexcom G7 sensors, transmitters, and readers if you meet these eligibility criteria.
How Much Does FreeStyle Libre 2 Cost Per Month?
The monthly cost of FreeStyle Libre 2 depends on whether you have Medicare coverage and your supplemental insurance.
- With Medicare Coverage (Part B):
- 80% of the cost is covered after meeting the annual deductible
- If you have Medicare Supplement (Medigap), it may cover the remaining 20%
- Some Medicare Advantage (Part C) plans may offer full coverage with no out-of-pocket costs
- Without Medicare:
- The cash price of FreeStyle Libre 2 sensors typically ranges from $75 to $150 per month, depending on the retailer and location.
To ensure maximum savings, check with your Medicare plan and pharmacy about potential co-pays and out-of-pocket expenses.
