As a pharmacy student, I can tell you that I see this stuff happen every day at work. If you can get your pharmacy to submit a prior auth form to your doctor, and can get the dr. to submit it to the insurance there is a decent chance that the insurance will then still cover the drug, especially if your dr makes it clear that your daughter has a long history. While I understand you had to switch doctors, there still should be a record of those changes and treatment failures in the practice records that your new dr can look at and see. In addition it very well may be that your insurance will pay for the brand Concerta, but not the generic. Drug companies love to give the insurance companies "rebates" that encourage them to only cover the brand name drug, and it seems to be an especially big trend in the world of ADHD meds.
Before you use a canadian pharmacy, please know that getting a controlled substance script from a foreign pharmacy and then "importing" it into the US is illegal. Realistically, the chances of getting caught are slim, as the government has bigger drugs across borders issues to solve, but if they ever started paying attention to it, you could get slammed. It doesn't matter how the drug is classified overseas, because here in the states it is controlled, and that is what matters to our government. If you were to drive across the border, and back into the country with the drug, you would be opening up yourself to an even bigger liability. The government doesn't mind so much on stuff like heart meds, and your standard non-controls (and to some extent actually driving across the border to get them for personal use, in a no greater than 90 day supply is ok with the gov) but they may use more scrutiny for controls.
If you were to try the Canadian route, you need to ensure that you are really doing your research. People know our drug prices are high, and that people in the US are desperate. Therefore there are plenty of less than trustworthy people running "rogue" pharmacies, that claim to sell you what your order, but that are really just sending counterfeit drugs, that at best have no therapeutic value, and at worst can cause more harm. I'm not saying that there are not legitimate places out there to order things from Canada, but it requires a lot of research on your part to make sure that they are legit.
And now, let me tell you that as a pharmacy student, I hate dealing with insurance. There is no rhyme, reason, or logic behind what they do, and often, they won't even tell me why they won't pay for something. Also, nothing would make me happier than for the government to join every other country in the world (except New Zealand) in preventing pharmaceutical advertising for prescription drugs...
