My daughter has been wearing insulin pumps since she was 2yrs old. She is 21 now and currently has a dying Tandem Tslim pump. She wants to get a new Tandem pump, and is due for an upgrade. The problem is that United Healthcare (UHC) has decided that Minimed is their "preferred" pump and all others are considered out of network, so they cost more. Has anyone had any success in getting UHC to pay for an out of network Tandem pump at the same price as the minimed?
