I think everyones clearances might be different depending on insurance. For me I must complete my Drs clearance, which includes: PRIMARY CARE CLEARANCE, PSYCHOLOGICAL CLEARANCE, UPPER GI SERIES, CHEST X RAY, ABDOMINAL ULTRASOUND,LAB WORK, NICOTINE TEST, BILATERAL ULTRASOUND OF LOWER EXTREMITY, EKG, ECHO, PULMONARY FUNCTION TEST. That is just from the Dr. My insurance requires that I use all of their people (dieticians,labs, nutritionist etc) but they also require me to do 5 EAP SESSIONS, AND OTHER MEETINGS TO GET CLEARED. AND I ONLY HAVE 2MONTHS TO GET IT ALL DONE.
