Medicare Changes to CGM Coverage

Continuous glucose monitors (CGMs) have become an integral piece of managing diabetes and have been steadily gaining popularity in recent years. Unfortunately, one of the biggest barriers to obtaining a CGM is insurance coverage and high out-of-pocket cost. On June 3, 2021, Medicare announced some changes that will make obtaining a CGM more accessible for people with diabetes. This recent change in coverage criteria is the first of many steps to making these devices more available for people with diabetes!
