I recently switched to getting my test strips through a 3rd party DME vendor. They said they could send me my strips with no co-pay when my pharmacy always dinged me for a $25 fee. After a couple of months of receiving test strips and getting no bill, I reconfirmed that I did not owe them anything and that they were being paid. So far so good.
I still wasn't sure and being the skeptic that I am I check out their web cite and found that they also offered Medtronic Infusion supplies. OK, let's see.
I called them and they said, "sure, we just need a prescription from your doctor. We'll take care of it." I asked how much they charge for the supplies and based on my insurance their price was $20.00 - my 20% of my 80/20 co-pay insurance. I suggested that is too low and somehow incorrect. I was informed that they are OK with 5% over what the insurance company pays them -- while Medtronic takes the full 20%.
Since I have always bought directly from Medtronic I was very surprised -- not shocked. Of course I called Medtronic to beef about such practices and was politely told that was their policy. I was told they do offer financial assistance if you are unemployed, make less than X , and so forth and so on.
So, if you are paying full price to Medtronic, you may want to shop around!
