We have Humana Commonwealth Optimum PPO. my husband already has this insurance I will be put on his plan October, but I was wondering what they require, is there anything I can go ahead and do and or how long does it take, what do they require? My BMI is 44.4, I do not have any documented problems, because I have not have insurance in 3 years. I have always been overweight. I have migraines and the normal back and knee pain as I am a nurse and work 12 hr shifts. ANY ADVISE ??
