We have similiar problems to those listed. We have fought it by using a couple of tools. First anyone who calls as a new patient for "back pain, neck pain, etc." is informed that our physician does not prescribe narcotics for this type of ailment and before you come in we will routinely pull a Pharmacy Board report telling us other doctors you have seen and medications prescribed. If they still want to see the doctor, then we charge $75.00 up front for all new patients without insurance and we collect that before they see the physician.
Once a doctor is known as a "wall" around our parts then we get very few calls. It is nice how well this community communicates!
