How can I get approved for laparoscopic sleeve gastrectomy?

What is the process like to get approved for laparoscopic sleeve gastrectomy? Do I have to get my BMI to a certain level? Right now I am sitting at a BMI around 50. Is that too high? It would be good for me to understand the body constraints before I go to initially see a doctor. I do not want to pay for a consultation only to figure out that I not qualified.
