The last pump.
The last D-tech before going on Medicare.
In early September I will purchase my last CGM system before going on Medicare in the spring. That will be followed by my final pump selection in early December. Rather than view these decisions with my usual excitement, I sit here with a stomachache of dread, frustration, and uncertainty. I tend to be naive and think that there is a “correct” decision when it comes to things like this, but there is enough going on in both the reimbursement and technology landscapes that I am faced with a lot of doubt.
First the CGM. It will be Dexcom for sure, but I am torn between staying with the G5 or going back to G4 platform. Although Dexcom is primarily marketing the G5, I use an Animas Vibe and have the option of staying with the G4 for the foreseeable future. (Please ignore the fact that I rarely use my pump as the CGM receiver. Click here for an explanation.) Currently Medicare does not cover continuous glucose monitoring for seniors with Type 1 diabetes. Many individuals and organizations are working hard for a policy change, but I am discouraged and convinced that I will have to self-fund my CGM starting at age 65.
Dexcom has made and continues to make decisions that make self-funding a CGM increasingly expensive. Looking at transmitters, G4 transmitters had a 6-month warranty but many of us experienced a much longer life than that. My most recent G4 transmitter lasted a year. G5 transmitters place a higher demand on batteries, but also have a software-mandated drop-dead date of about 100 days. Thus for someone who self-pays, transmitter costs have almost doubled from G4 to G5.
As yet no changes have been made that impact the cost of sensors. Unfortunately as reported at Diabetes Mine last week, the Dexcom CEO brought up the idea of Sensor Auto Shut-off during the latest quarterly earnings call. This was presented as a safety consideration and my initial snarky response was tweeted by Diabetes Hands Foundation: “So we can kill ourselves on Day 1 of a sensor when Dex is at its most inaccurate, but not on Day 11″ bit.ly/2b4fmjx @MNAZLaddie.” In Dexcom’s defense, no one can ignore the financial repercussions to Dexcom of customers using sensors for 2-3 times as long as warrantied.
I currently use most of my sensors for about 2-1/2 weeks. I have full insurance coverage for sensors, but experience better accuracy the second week than the first. I often finally change out a sensor for scheduling reasons or because it falls off despite SkinTac and additional tape. Very rarely is it because of performance problems. I doubt that there will be sensor auto shut-off until the G6, but it is another change that will greatly impact those who self-pay.
I think it makes sense for me to return to G4 for now, especially since I can use the Share feature to see data on my phone. Going back to carrying a receiver won’t bother me much, especially because I like the alarm profiles of the receiver much better than my phone. I am also tired of keeping my phone with me all of the time.
The CGM decision is tangled in my thoughts about a new pump. I am not in love with the Vibe and it doesn’t make sense to buy another one. Tandem is close to retiring the t:slim G4 and I know that if I go with Tandem, I would prefer to buy the t:slim X2 to be released in the fall. The last time I selected a pump for CGM reasons was the Ping in 2012 and it wasn’t a good choice for me. I’ll be writing more about pump musings in the fall, but as with previous pump decisions, it will be complicated by insurance considerations and the uncertain release date of new technology. Medicare rules will also come into play.
One undiscussed topic in today’s post is: If the cost of using a Dexcom continues to spiral upwards and there is no Medicare coverage, at what point will I choose to live without a CGM? Going back to the second paragraph of this blogpost, that is the sort of decision that fills me with “dread, frustration, and uncertainty.”
I sometimes conclude technology posts with the admission that my concerns are a #firstworldproblem. I am a privileged patient when it comes to diabetes and I am grateful.
