As hackneyed as this sounds, following this simple rule will address most, if not all credentialing issues. And, in many instances, it is precisely the kind of behavior an MCO is trying to encourage. Under the rubric of practicing good medicine falls proper documentation, adherence to standards of care and the like. When the physician does these things, the potential for an adverse credentialing decision is greatly diminished. The medical director can be your ally.
Most physicians exhibit a visceral reaction to the medical director.
On the cynical side, they can make or break a practice by decredentialing the practice's physicians. But medical directors serve an increasingly legitimate role in assuring quality care and keeping costs down. And under managed care, the role of medical director isn't about to go away any time soon. So the medical director should be treated with the dignity and respect that a referring physician would be afforded. Ask for help.
