@emonie71 you have to have all of this stuff done before hand and sent in with the paperwork BEFORE the insurance company approves you. Every insurance is different, so check with your doc and insurance coordinator be sure of what the paperwork requirements are. No sense of getting denied when all of your stuff hasn't been put in.
I have 5 more months ahead of me before I can get surgery approval because of the required 6 month supervised weight loss requirement by a physican. Just hoops and ladders to make one wait. SMH.
