If you get denied how long do you have to wait to appeal or apply again?

Depends entirely on your insurance and the reason for the denial.

This. Ask your insurance company and/or surgeon's office for a copy of the denial letter. That's exactly what I did when I was denied. The letter specified the exact reason for the denial, and the surgeon's office is working with me to address the issue (supervised diet requirements in my case). I suggest you start by calling the surgeon's office. If they do a lot of weight loss surgeries, they will be able to guide you through this.
