I believe you are right and the requirements of your surgical center and insurance company may vary. I initally dealt with a surgical center that required me to use this particular psychiatrist for psych evaluations. No one else. However, he only did them two days a week. Same thing with the sleep study people. At that rate, they could only see me two to three months later. So I consulted with a different facility, and they just wanted the evaluation wtih a licensed person in my area.
If I had remained with the first place, I would have had my sleep consultation (not the study) at the end of July and likely would have just now had my study done. My appointment with "their" psych guy would have been later this month. Instead, I'm nine days away from having my SURGERY . I don't know where you live, but if they insist on that one year rule, you may want to check with other facilities in your area. Just sayin. Good luck to you.
