Hey MH, Every insurance company has different policies, I know you don't want to go through another month and not know untill your at the pharmacy if they are going to fill a DAW or throw up another control or limit , but this is becoming more and more common. It saves them money by limiting the dosage or doses per month and making you use a generic.
The best thing to do is call your insurance company and find out if they have a policy regarding DAW when a generic is available or a policy on quantity per month that would prohibit TID dosing.
With all the medicare research I've done this month

all I can say is every company and the policy your covered under has their own twists. It would be best to find out what your insurance companies twists are and be able to go back to what worked rather than using BT meds to fill gaps instead of true BT pain. What happens when you need BT pain meds once they become nothing more than gap fillers for less effective generics. It's that or increase the generic LA dose to accomadate the generic' short comings.
I just hate to see you go from a working plan to one that sets you up for problems and having to go back to clock watching and having to take a pain pill 6, 7 or 8 times a day. That kinda defeats the whole purpose of LA meds and will leave you without true BT meds.
Hope you get it figured out before your next apt. Pharmacies aren't usually much help unless you have a common plan and they know it's policies very well. There response will likely be, "we won't know untill we run it through." Your script providor should be able to give you definitive policy answers.
Good luck, Dave
