I am scheduled for sleep test on 9/30/16. I spoke to my insurance Oxford and they have not received a request for authorization from you. I have already had to reschedule this test because your office did not request authorization. I cannot have this test without authorization. Oxford gave me a number that Dr. Sagalovich can call to speak directly with their doctor: 800-666-1353. Please call me and let me know what to do, thank you.
