Does Medicare Cover CGM Devices 2025? Complete Guide

If you or a loved one manages diabetes and relies on a continuous glucose monitor, you may be asking: does Medicare cover CGM devices 2025? The answer is yes - Medicare does provide coverage for CGM devices, but eligibility requirements and coverage rules apply. Understanding exactly what is covered and how to qualify can help you access this life-changing technology with minimal out-of-pocket costs.

How Medicare CGM Coverage Works in 2025

Medicare classifies continuous glucose monitors as durable medical equipment (DME), which means they are covered under Medicare Part B. In 2025, Medicare continues to expand access to CGM technology for beneficiaries who meet specific medical criteria. Coverage typically applies to both the CGM device itself and the ongoing supplies needed to operate it, such as sensors and transmitters. Patients are generally responsible for 20% of the Medicare-approved amount after meeting their Part B deductible.

• CGM devices are covered under Medicare Part B as durable medical equipment

• Both the CGM monitor and necessary supplies (sensors, transmitters) may be covered

• Patients typically pay 20% coinsurance after the annual Part B deductible is met

• Medicare Advantage (Part C) plans may offer additional CGM benefits beyond Original Medicare
