My ten-year-old has only been covered by this company through Medicaid for a few weeks and we're already having huge difficulties. My son is a type 1 diabetic, which means he is insulin dependant. I was shocked to realize they didn't approve one of his insulin prescriptions (he will die without this insulin). They then approved another form of the insulin, cartridges. These cartridges are for a device we do not have; and, apparently, they don't cover the device, and I can't even get it from the pharmacy. I have a box of insulin we can't use. I called Friday, but it was too close to 5pm so when I was transferred no one was there to talk to. Way to deprive a child of his life-sustaining prescription. I will be calling the other insurance providers to see if they will actually cover my son's necessities. Also, according to MO HealthNet, I am supposed to be able to choose a specialist as a primary care physician because he has a chronic illness, HSH said I could not so now I need to call the state, as well. Frustrating fiasco.
