Hello and welcome back Grammaof5! Took me a a long time to clear the insurance hurdle after my initial denial but I persisted and eventually was approved.
My denial was based on not proving sufficient medically supervision to diet (even though I had done Jenny Craig, Nutrisystem, another meal delivery program) and lost weight and visited the doctor; they claimed I didn't visit the doctor with sufficient frequency to prove he supervised. So, I enrolled in a 800 calorie liquid diet program where I met, for nearly two years, with a doctor every week for weigh in and counseling that he documented in notes. It was all worth it!
