Well, typically you first need to see your primary care doctor and have them refer you to a bariatric surgeon. You should also reach out to your medical insurance to see what is, and isn't covered and what restrictions or qualifying factors they are looking for to approve the procedure.
Most insurances require a certain BMI or higher, or a lower BMI plus co-morbidities like sleep apnea or high blood pressure or diabetes to approve the procedure at a lower BMI.
A quick search online and I found this:

it's a bit older, but it'll at least get you into the "Ball park" range for what is and isn't covered and when.
