My cardiologist at UCLA just tried to get a pre-authorization for a tilt table test and it was denied by Blue Cross Blue Shield of Illinois. The basis of their denial is that I haven't actually fainted. I have had a previous TTT in 2011 at the Mayo Clinic in Arizona that resulted in the diagnosis of POTS. I have an atypical presentation, with my blood pressure bouncing up and down during the test. The purpose of the retest is to see how well the beta-blocker I am on is working. I plan to appeal and was wondering if anyone else has done so and had any suggestions for me. Specifically, I'm looking for help with recommended verbiage and medical literature citations.
