I'm just getting going on all this (starter kit just shipped).
Have Anthem/BC here in CA, and not one of their more deluxe plans (small company, can only afford to offer high-deductible, copay-based plans).
Still, A/BC approved the whole shebang, and I don't have a special circumstance (like hypo unawareness) to justify it. I'm going CGM simply because I want to achieve non-diabetic BG levels of control.
Only "condition" had to meet was having at least one hypo episode below 50. I've been in the 50s once, but not under. We fudged it, given the accuracy my GCM, my 52 very well could have been 47 (52 +/-5), so we went with that. They took it.
Short-sightedness is such an epidemic with business. I am not a supporter of Obamacare, or government sponsored/run health care generally. However, I do support regulation that changes the economic calculation so that it is in an insurance company's financial interest to plan and operate on the long term rather than the short term.
As it stands now, future costs avoided due to smaller aggregate spending now just doesn't figure in the calculations. The fact that doing (relatively) expensive CGM now and avoiding hundreds of thousands in costs later to deal with complications doesn't register, because there's no surety you'll be their customer then, and they'll have to pay those costs.
They have to satisfy their shareholders today, not prospective shareholders 20 years from now while you're having amputations, heart bypass surgery, laser retinopathy treatments, in-home care assistance, and on and on -- because you weren't able to get a CGM earlier in the disease and keep it under good control.
I don't know what the public policy answer is. I have a few ideas, but nothing I think american society would ever be willing to adopt.
