Pain med not covered by medicare

[Lisa]

Hello!

Since a crash this summer, I have had a whole lot more pain off and on compared to ever before. In a doctor apt last week, I finally accepted his offer of a prescription for the pain - but in trying to fill it today medicare/medicaid doesn't cover it. My doc is doesn't really seem to know what is or isn't covered by medicare so this makes things a bit harder when you need something.

I was wondering, how do you go about trying to get something covered by medicare that isn't automatically?

Thanks!
Lisa
