The BCBS plan probably negotiates one national price. The difference between the hundreds if not thousand types of plans is the copay/coinsurance/deductible as far as DME is concerned. There is also differences in pharmacy benefits, dental etc. I know with my current BCBS plan, I paya 30% coinsurance on DME, another on I have access to the coinsurance is 15%. I am probably going to be staying with the 30%, because if the Animas Vibe is approved in the US sometime between now and next year, then I know that I will reach the catastrophic limit, and for some part of the year, pay nothing. My son does not want to use a CGM until the Vibe comes out (no more room in pocket issue). I am looking for people who have BCBS plans with Dexcom as a network provider. If they give me the price they pay, and the % of coinsurance their plan has, I can convert that to what I would pay at 15 or 30%, and that way get a ball park figure that may or may not be 100% accurate, but will give me a better idea of what I would have to pay.
