It sounds like your appeal process is bit more daunting than what i have experienced. When my insurance refuse coverage for some med I need I check the box to appeal and and have my physician send a note on why I need it and they have always so far approved it. One time the pharmacy kept at it for three months to get it done but that was due to lack of response from my physician at the time so I had to replace her with one that is more responsive to my needs. Another doctor suggested the need for me to change cause I guess it was widely known by her peers that she was swamped by her caseload.
