I did not make the change over to the Contour meter when we got Eric's upgrade a few months ago (moved from a 4-year-old out-of-warranty 522 to the Revel) because MaineCare would only provide a single meter. I have 3 of the One-Touch meters that connected to his old pump, and lo and behold, they also work with the new pump — the prime difference, as far as I can see, is that they can't be uploaded to CareLink.
I think your best bet is to write to the people who manufacture the Contour and see if a) you can get them to supply you with free or discounted test strips, and b) if they might work on CVS/Caremark to reinstate their product in its formulary. It does not benefit them economically to have patients unable to access their product due to cost considerations. But in the meantime, find out what test strips ARE on the company's preferred formulary, because if they do allow OneTouch strips, there are OneTouch meters that will talk to Medtronic pumps.
