Finding the right place can be a lot of searching and a little luck.
I was in the "lucky" category - my PCP knew exactly where to refer me.
My sister had to search - she started with her PCP, who only believes in PT and medication, got frustrated and began asking every medical professional she knows (she's a retired nurse.) After a few "false starts" she finally found someone in her insurance network who she thinks she can work with.
I was able to go to my insurance company website on the provider page and search for pain management clinics. This is what you want to see - staff with a number of specialties - internal medicine, pain management, psychology, PT or OT...
Do you live in or near a metro area? That seems to be the easiest place to find outpatient care. Or you can apply to one of the Mayo Clinics, which it is a 3 week commitment, full time at one of their facilities.
