I'm not entirely sure, but it makes sense that you wouldn't want to have the preop testing done until you know for sure that your insurance has approved you (unless you are paying portions out of pocket?). When I met w/ my primary physician, he told me to hold off on the preop testing until I knew I had the green light from my insurance...reason being, if I was denied, and had to start from the drawing board that I would have had all that testing done for no reason. Has the request to insurance been processed?
Orignally, the center I am going through scheduled me for a June 2nd surgery date - before having any approval from insurance. Because it took a bit longer to get all my ducks in a row (letter of referral, medical records sent over before the request to insurance was put through), I had to push my date back to June 30th. But by the time I had all those steps done, it was w/in 10 days that the insurance approval came back.
Good luck...I hope everything goes smooth and easy for you!!
