Mine was supposedly submitted on 3/20 and I called my Dr office every week, finally on 5/3 I called my insurance company directly and they said they had never received it....don't know where my surgeons office sent it...or IF they did on 3/20, but I jumped on them, they resubmitted it 5/3, got denial 5/16 because some forms were missing, appealed 5/17 with the missing forms (which the surgeon had but failed to send in the first time) and approved 5/20!
Major point here.....follow up directly with your insurance company to be sure it was submitted and is being reviewed right away...then you magi get approved quicker than I did. My surgery is next week June 26!! Good luck to all of you!
