Waiting not so patiently!
So find out who that person is at your office. Then call and say, "Hey I'm just checking in to make sure everything is in and I have completed everything I need for you to file my claim." Make it seem like you are just nervous and want everything to work fine (which is true)... and that's something most bariatric clinics are used to. My insurance lady even said (after I apologized for calling back a bunch of times), "Don't worry. I know how it is. It seems like a long tunnel, but I promise, you are almost at the end."
Seek answers - "When will it be submitted?" "Who is in charge of submitting." It's your job to have them remember you and your case.
In the meantime --- after doing all that --- find a hobby, lol. Or you will drive yourself crazy.. :-)
