Last time you heard from Dr. Mastrototaro, he gave the short description of how Medtronic’s integrated CGM works. Today, for those of you who might want to know more, he goes a bit more in-depth, explaining the roles of the sensor, transmitter and insulin pump in the system. He also talks about what goes on in the pump to calibrate that sensor.

What part of the sensor is changed to result in the expiration of the unit?

@Cathy Nice to hear from you, but I’m not sure what you’re asking. I’m sorry if I’m being dense, but could you explain your question a bit more/what change you’re referring to?

Now the Mini Med 530 G with Enlite for sale in the United States and the sensor can be worn with improved accuracy.

As a Medtronic / MiniMed customer since 1994. I understand Medtronic has been working to have Medicare cover the CGM system all year long..

The new MiniMed 530G with Enlite even with the Medtronic up grade program Medicare will not cover the CGM or supplies.
In order for Medicare coverage to occur an important first step needs to be taken by CMS (the agency that runs the Medicare program) that establishes CGM and enabled insulin pumps as durable medical equipment. The question is….how much longer will it take for CMS to establish coverage and payment for the advanced insulin Pump technology and CGM? They have not made a decision to cover the CONTINUOUS GLUCOSE MONTORING SYSTEM in more than a year.

This puts seniors on Medicare and other diabetics caught between quality preventive medical care and decisions to not cover proven health care technology. This simply means the diabetics are in a position of not being able to afford the costs of this wonderful, extremely effective technology.
The CGM is expensive; however, its annual cost is low when measured against the cost of one ER or hospital stay due to a serious low and or high blood glucose event.
Preventive care should be the cornerstone medical policy for all healthcare insurance here in America.
I hope The Loop can be source of help in having Medicare to provide
coverage of the C G M system. Time for Medicare to do this is long over due.

Looking forward to hearing from you.
Yours truly,
Roy Taylor

Hi Roy. Thank you for your comment, and putting your trust in us for all of these years. I do not have a timeline on when Medicare will provide CGM coverage, but please know we are continuing to actively work with the Centers for Medicare and Medicaid services to establish coverage consistent with other healthcare insurance companies. We suggest that you talk with your health care team, so they can advocate for CGM coverage on your behalf. Please let me know if there’s anything else I can help you with.
