Hi there I just did this, the original surgeon's office had everything they needed for 5 months and never submitted it. I found out they finally submitted my information March 29th and I had an approval 2 days later. I was not comfortable using that office and was quite upset so I went to a different surgeon recommended by my doctor. The original office had to contact my insurance and void the authorization and then the new office was able to submit for approval. Took 3 days, no problems and my surgery has been scheduled for May 3
