My SSDI was finally approved and I'm now on Medicare. I enrolled in Part D (the prescription coverage) and they automatically enrolled me in Humana Pharmacy....thing...whatever. Two questions. The Humana card is a "Walmart Preferred" card, meaning I get special deals only at a Walmart pharmacy. I don't use a Walmart pharmacy and I don't want to. I've had all of my prescriptions at CVS for years - and I have *a lot* of prescriptions. They know me - I don't even have to give them my name when I go in - and they know what I take and if I should be watching for anything. Am I stuck with the Humana, or can I change? And if I can change, do I have to wait for open enrollment this year since this was just assigned to me? Next, it didn't cover my Klonopin because it's "not covered by law". The pharmacy tech printed the screen that stated that, but she doesn't know why. It's not an expensive drug, so it's not a big deal, I'm just curious why it's "not covered by law". I know it's a benzo and is a controlled substance, but it's not *that* controlled. Is this going to apply to other controlled drugs, or is there another reason why it wouldn't be covered "by law"? TIA.
