Has anyone been approved for surgey through medicaid?

Ive heard its really hard to get approved. I went to Dr. Richards for the consult and am currently on my six month Dr supervised diet. She seemed ok, not overly friendly but I had a better experience there than I did at South Valley. I actually had a surgery scheduled in Feb. through them but as a self pay but backed out because they were really pushy about getting me in. I didn't like what the doctor said in one of his seminars- "You can pretty much eat whatever you want, just in smaller quantaties" I feel like this is SO not true. YOu can't just eat whatever you want. Anyway my husband became self employed and trying to get his company up and running we qualified for medicaid. I was surprised that they do pay for it, I am just so worried that I will do the six month thing and then they will come back and say, no, we wont pay for it.

If any of you have been through this before will you please tell me about your experience? What you had to submit, tests you had to take, denials or approvals and how long it took.

THank you!!
