I currently use Fiasp in my Tandem X2 pump and love how quickly it acts but hate that I have to change my infusion site every 2 days. If I try to extend the infusion set to the 3rd day, the effectiveness plummets and my BG is all over the place.
I recently tried a couple of vials of Lyumjev in my pump and it worked a little faster than Fiasp. In addition, I experimented with extended infusion set usage and could extend the infusion set to 4 to 5 days without any apparent drop-off of effectiveness. This was wonderful news for me!
That brings me to the reason for my post. Since I use insulin in my Tandem Pump, I get my insulin through Medicare Part B (rather than Part D). In my case, my supplemental insurance covers 100% of the Part B copay so the 90 day renewal of my insulin is zero cost to me. When my doctor sent in the Lyumjev prescription to my local CVS pharmacy in November of 2021, it got rejected because it isn’t in the Medicare Formulary so Medicare wouldn’t cover it.
I’ve searched everywhere for the Medicare drug formulary but can’t find it. My hope is that Lyumjev will get added in 2022 but I don’t know if that is realistic or not.
Anybody have any insight into how long it takes, after a new insulin is FDA approved, for the insulin to be covered by Medicare?
