Re: Haven't signed an agreement...
The smart thing to do is to always let your PM doctor, contract or not, about any treatment that you may be getting from another surgeon, doctor or dentist, especially if it involves scheduled medication- ie DEA scheduled medication. Since the surgeon is in another state, once you are discharged to home, you most probably would be treated for any pain resulting from the surgery by your PM doctor anyway. Usually my PM has the surgeon treat me during hospitalizations and for the month post op for pain medications related to the surgery and then he takes over.
I have been in pain management for some time and I always make it a practice to let mine know about any problem that comes up that might involve surgery or pain medication so that he is aware and he works with my other care givers to make sure that they are both on the same page regarding medication needs. It protects me and makes my life simpler.
