Definitely work with your lawyer on this. WC has a way of trying to wiggle out of things...often with lies and half truths. I don't know the laws in your state but your lawyer can help you navigate this. A lot depends on whether or not you are allowed to choose your own doctor and what the rules are with that.

Also important is what the laws were when your injury occurred. For example, in IL when I was injured the law was that the injured worker got two choices of their own doctors. Now the law is one choice AND you have to choose from a list of doctors approved by work comp. In my case, even though the law has now changed, the previous law is what applies in my case (or would if I hadn't settled). Work comp tried to tell me on a number of occassions about the NEW law (so did MY lawyer but he was a jerk trying to bully me) but in my case the old laws still applied.

So you really need to rely on your lawyer for this and I hope they are good and know their stuff. The laws vary so much from state to state and you really need an expert.

But the good news is that the IME report agrees with what your doctor said. They have no good reason to deny treatment. Your lawyer should be able to petition the courts to have treatment ordered if that is the issue. Better to do it sooner rather than later. Often all it takes is the scheduling of that hearing for work comp to do what is right.
