Dr. Cirangle is my doc and I love him. I don't have a band, but I don't think that will make a difference in how long it takes. He says with insurance it generally takes around a month. Some of that time is spent submitting and getting approval so it's going to depend on your insurance company though.
The pre-op tests are pretty standard. There is variation based on your medical history but at a minimum you should be getting a physical, an EKG, an X-ray or Upper GI, and lab work. Women have to have a pap and mam within the last year. Everyone does a NUT consult where they go over the diet and a psych eval as well, even if your insurance doesn't require it. They have an in-house dietician and counselor you can see, but you can use your own too.
The after-care program is awesome and it's why their results are better than published averages. They have support groups all over the Bay Area every month. There is a newsletter too. In addition, you have full access to the on-staff dietician and counselor, pretty much as much as you need them. Fills are included too. Dr. C likes to see his band patients every month -- some docs make you wait 6 weeks in between fills and that can be frustrating and often leads to people getting off track.
You get so many months of after-care included in your program fee. I don't know exactly how many. It's a least a year, but more likely two. I was self-pay for a
sleeve and my price includes two years of after-care.
