Yes, that's been happening with several other medications. You see, Delta chooses which prescription drugs they want to cover and which they don't want to cover if you choose one of the non-contractual health plans. You can always try an appeal but you're likely to be told to go pound more sand.

This is why i'm always surprised that your PWA has so little in it when it comes to health insurance plans. Most ramp agents at other airlines have more protections when it comes to their health insurance than Delta pilots.
