San Diego-based DexCom is partnering with UnitedHealthcare to help people manage their Type 2 diabetes through wearable technology.

Under a pilot program unveiled this week, Minnesota-based UnitedHealth will provide DexCom’s glucose monitoring device to some in its Medicare Advantage plan to better monitor glucose levels. Also offered: personalized coaching to understand and act on the data.

The pilot will include a portion of the 4.3 million people covered by UnitedHealth’s Medicare Advantage.

The intent is to better manage glucose levels, in turn spurring reductions in medications and improved confidence in managing diabetes.

Dexcom’s technology consists of a sensor that reads glucose levels just beneath the skin. A transmitter sends the data to a smartphone, which processes and displays updated data every five minutes, and can reveal relationships between eating, exercise and blood sugar that are difficult to observe with only test strips and a glucose meter.

“Continuous glucose monitoring can be a game changer for people enrolled in our Medicare Advantage plans, as the data can be translated into personalized information that can be acted upon in real time,” said Brian Thompson, CEO of UnitedHealthcare Medicare & Retirement.
