Yes, i used the bcbs fep and the process was suprisingly easy. You need to have 3 months of dietitian visits prior to submission, proof that you've been obese(hate that word) for the past two years. You can prove that simply with just regular doctor visist weigh in records. You need the pysh eval as well along with proof that you've tried other diets and failed. You can achieve that simply by having the dietitian record everything you tried. Hope that helps and good luck on your journey.
