Do you have your plan benefits handy? If so, it should say whether or not you need pre-approval (I'm guessing you don't, based on comments you've made in the past about having such a good insurance plan), and then to check if there are any limits to the number of visits. I don't want to mislead you, but my thinking is that it's no different than if I were to see two different chiropractors at the same time. The insurance company only cares whether or not it's someone contracted to accept their terms, and then whether or not you are staying within your plan's limits.

It really comes down to how the plan interprets the service, but I can't see why they would care who they are paying as long as it's a covered provider. After all, you're just trying to find the right therapist.

Again, I don't want to mislead you. I'm just talking off the cuff.
