I used to work in a pain mgmt clinic so I understand your concern. As far as HIPPA is concerned, as I understand it, providing medical information is allowed for the purpose of providing care. So letting another MD know that your dr is treating the pt as a primary care provider, I would think would be allowed. We used to send a letter to all MD's invovled in our pt's care (that we knew about)
a letter stating this and asking them not to prescribe narcotics and sedatives for the pt. As far as the pts go, I think many times the pts are more afraid of the pain that just needing a fix. (Most of them anyway). The American Society for Pain Management has a website and links that might be useful,
