Dexcom Users

For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (, which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

Hi - Did you take Tylenol? That will do it. Something in the chemicals throws off the CGM.

Sometimes the Dex is right on the mark... and other times it is so off. The main thing is to not believe it when correction bolus or when treating lows. I have gotten lazy and ties and believed the middle of night alarms, only to wake up in bad shape.Hopefully , they will get better with time.

Me also had a higher reading than I test on my fingers. In the night my CGM vibrated and showed that it is 370, but I checked my sugar it was 140.

Does anyone have a higher reading than when you test on your fingers? Mine is away off. This morning it read over 300 and I checked my sugar and it was 160.

It's just Tricare Prime - I was just responding to Sandy about that. Unfortunately I don't think it's related to your issue of Medicare coverage. The people I know on Medicare with type 1 also pay out of pocket for the Dexcom. sorry.

Comment by Natasha Bowlds on December 14, 2011 at 9:02am

We have Tricare Prime and have all our omnipod and dexcom supplies 100% covered for my son. I had to appeal for the Dexcom because of his age, but it was approved.

Comment by Sandy Palmer on December 14, 2011 at 8:05am

Brevard, just to warn you. Tricare sees the sensors not as supplies and Tricare Prime does NOT cover any part of this. I faught for years with every med nec letter from every specialist you could possibly ask for. I do not see Tricare for life being any different.

Comment by Brevard Den and Sal on December 14, 2011 at 7:58am

There may be hope in the future. My husband who has been on Medicare for 8 years happened to ask if Tricare for Life, who is a secondary payer for us will support the Dexcom? They will, at 80% after a his $150 deductable has been met. Diabetes Management and Supplies in Harahan, La. did all of the leg work to make it happen in about two weeks of time.
Tricare is known to support very little that Medicare does not cover and we are both thrilled and greatful.
The Dexcom has made such a positve influence in both of our lives.
