Medicare and the medtronic CGM


Great. It’s liberating to not have to constantly break out my meter to test a zillion times a day, plus I get a heads-up to impending highs and lows. I sure could have put my CGM to good use years ago (whenever it was that Dexcom came out with their first accurate unit)


This is a good point. @Amy2, if you want to use this data-point to correct and you want to be conservative, you can take the average of 119 and 136 and use that number.


Medicare will approve G5 from Dexcom


She wrote 11 days ago that she was approved for the Dexcom…


Good morning all. My daily question concerning my new Dexcom 5. Do users find that they lose signal frequently. For no apparent reason. My Dexcom receiver seems to work better than my iPhone in connectivity? Is it my carrier? Love love love not sticking my fingers. Has helped with my low overnight numbers that I did not know were low. Reduced basal rate a lot. Thank you :pray:


It would be better for you to post your question in your own thread. it doesn’t match up with this thread’s topic.


Ok. Thanks


The G6 has three significant advantages: better control (best accuracy available at MARD 9.0); less neural and other damage (Basal IQ algorithm, which reduces/avoids hypogylcemic excursions); and freedom (codes replace the need to test for blood glucose levels). I don’t see how you can blow these off so easily.

I use the upgradable Tandem X2 w/ G5 and am trying to find a way around Medicare - and in so doing, I’ve discovered that all suppliers are forced to sign a contract with both Dexcom and Medicare that prevents (1) those who have Medicare and Medicai to take advantage of automatic crossover if they have it, and (2) prevents suppliers to submit directly to Medicaid. The result is that those who do not have private insurance that covers the G6 and cannot easily afford the G6 OTC costs have no way to acquire the G6. Moreover, Medicare is considering (or has already implemented - I’m not certain) requiring Dexcom to force the G6 sensor to stop functioning after 10 days, preventing users for extending it’s use for several days.

We should all be very disturbed by and vocal about this public/private sector arrangement to prevent those who most need the G6 advances (low income and poverty are causal factors in depression and poor health) to obtain them.

The same goes for those who want to use the Medtronic 670G (I’m not one of them): The 670G has been on the market for two years, but Medicare has not yet given Medtronic an estimated date of coverage.


I’m not following you:

  1. The G6 has a lot of teething problems. Go look all around the web at the complaints about sensor errors, not getting even 5 days out of them, much less 10, accuracy isn’t always what it’s cracked up to be, AND inferior adhesive.
    2)Why are u blaming Medicare for a business decision by Dexcom to limit the G6 (which can be circumvented) to 10 days?
    3)Medtronic’s sensor aren’t very good, so I don’t blame Medicare for not wanting to be on the hook for an inferior system. Medtronic has failed to take advantage of its years of preeminence in the sector. They didn’t innovate like they could/should have.
    4)Your “public/sector…” comment sounds like socialistic thinking to me. Nothing more. :slight_smile:

To read about tons of issues with the G6, become a member of the Facebook group “Dexcom G6”. There are messages after messages of problems with Dexcom’s latest sensor.


I really, really hate seeing comments like this. I don’t understand toniobiko’s line of thought and don’t wish to go into politics here, but to me there is nothing wrong with “socialistic thinking” as it is social conscience and definitely NOT communism that some Americans equate it with.


:slight_smile: oh well! it still sounds like socialist thinking. who said anything about communism? not me.


Per my reading and understanding, Medicare has already (implicitly) stated that the Medtronic cgm in its current approval state is not eligible to be covered under Medicare. As the cgm is (again per my understanding) central to the purpose of the 670g (as compared to other Medtronic pumps) there would be little point to Medicare covering the 670g but disallowing the use of the Medtronic cgm system.

I believe the onus is on Medtronic to have their cgm system approved to the standards which Medicare has provided so as to allow coverage.

I think a good example is Abbott which submitted their cgm for the proper approvals so as to match up with what CMS/Medicare had already stated was the requirement for coverage.


So what is wrong with tempering our runaway capitalism with a little social conscience (socialism)?


What Tim wrote.


Since the 670 G with the guardian sensor has a closed loop system it is simply amazing how much better your blood sugar control is. I was not a fan of Medtronic sensors At ALL (used medtronic pump with Dexcom sensor) until the 670 G came out w the Guardian sensor. Since it has a closed loop system it is simply amazing how much better your blood sugar control is. At this point the way it works w the 670 pump is outstanding.


I’d never refer to the 670 as “closed-loop”. It is hybrid closed loop, at BEST. too much marketing BS confuses people. :slight_smile:


Hi Amy, I was able to start on the MT 670G my last year working and it was covered along with the CGMs for minimal costs. I was told by many at Medtronic that it was only a matter of time before Medicare which I was eligible for at the end of that year would likely cover Metronic 670G sensors. Not true. So I kept my 670G and started using the Dexcom G5 which I really like a lot. My Medtronic warranty is not up for a couple of years. However I was able to work it out so that I could use Medicare coverage to handle the cost of renting a Tandem T:slim 2x. I think the Tandem platform (visuals and ability to navigate through pump features) is so much better than the MT 670G platform. On top of that, Medicare just approved use of the Dexcom G6 and it will be available to those of us covered by Medicare in the next couple of months. I am totally psyched about this. Once I start using the G6 with the Tandem pump I will have the benefit of pump insulin delivery shut down when my sugars start to go down and it will automatically resume delivery once my sugars approach normal levels. This new feature of the Tandem and Dexcom CGM communication will be a signficant game changer for me and my wife.



Can you explain what you mean by using Medicare coverage to rent a Tandem X2 pump while your current MT 670G is still under warranty?


The company I now order my pump supplies (CGMs, Infusion sets and cartridges) Solara set it up. Not sure of any other details other than that. What it means is Solara will still own my Tandem until my warranty for the 670G expires. Then Medicare will pay for any remaining amount owed for purchase of the pump (at least 80% of costs I think). I recommend contacting Solara or Tandem to get details. Sorry I don’t have any more information on this.




Good info. Sounds like an innovative arrangement.
