Are you covered through Target?
I have Type One Diabetes and currently use an insulin pump. My insurance (covered through Target) covers 80% of everything once I hit the deductible. Have you taken a look on the pay and benefits site and seen what your insurance covers for, I think it's, durable medical equipment or something close to that wording? You can also call them and see what options they have. Like, I know I can't get my supplies directly from my pump company, I have to go through a third party seller to get them to cover the 80% of it. But they should cover at least part of it and have options for otherwise, either through the insurance or the pump company themselves.
