I have heard of some psychiatrists charging what sounded like outrageous fees, but then doctors do too if they are not taking insurance and there are some who do not.

Mine has shifted a few times and now I think has a deal with a university to take the student insurance, but everyone else pays out of pocket. Luckily, he is not greedy and actually charges very low fees considering.

I think dealing with insurance is a real hassle. You have to justify why something is medically necessary all the time and I think in some case the insurance interferes in the kind of services provided. Plus sometimes they have to hire someone to manage their billing so it becomes an expense.
