Humana Gold Plus HMO (medicare)

Does anyone have it and how was it to getting approved, I am on disability so on March 1st my medicare kicked in before that I had just medicaid and was approved on Jan. 29, and was going to have surgery in March, but the hospital that would take medicaid was not a Center of Excellence so I had to change dr.'s and hospital. So now I have to wait till I can get approved on Humana they have everything from the other dr.'s office. The new dr. wants me to have a stress test done, some more blood work, an EGD which was done this past Friday, and see thier Nut. everything else will happen on the 30th so I hope they can get the approval by then with everything I already had. BMI of 66 with comorbidities of severe sleep apnea, high blood pressure, and lymphadema in my legs. Any information would be greatly appreciated. Thank you in advance Sabrina
