Sleep study
I agree - I think it depends on your insurance. I did my sleep study and my psych. evaluation prior to the other appointments., but I am self pay. If you are self pay, the main thing I was told was to be sure you were accepted for the surgery first so you don't pay for the sleep study and then find out that you can't do the surgery... then you would have spent the money for no reason. I hopes this helps a little.
