The financial folks at your clinic may be able to tell you their past experience with your particular insurance. But past practice is no guarantee of current practice. I had coverage with a different insurance company, and my clinic previously found that that company would approve IVF after three failed IUI’s. But then the company changed its internal practice to require 6 IUI’s (no change in the coverage language, just a changevto internal practice) so we ended up paying for IVF OOP.
