I feel your pain Grovers,
After back surgery years ago, I was prescribed a wonderful NON narcotic painkiller. Worked great. The insurance company decided it was CHEAPER for them to prescribe me the narcotic CODEINE instead. I fought for years to get them to allow the non narcotic drug instead, and eventually my doctor backed me up and now the non narcotic drug is covered.
My suggestion is to get a doctor on your side; they do have a bit (not much) more pull with the insurance companies than we do.
