Nurse practitioner challenges to the orthodox structure of health care delivery: regulation and restraints on trade.

Until recently, physicians have been the primary health care providers in the United States. In response to the rising health care costs and public demand of the past decade, allied health care providers have challenged this orthodox structure of health care delivery. Among these allied health care providers are nurse practitioners, who have attempted to expand traditional roles of the registered nurse. This article focuses on the legal issues raised by several major obstacles to the expansion of nurse practitioner services: licensing restrictions, third party reimbursement policies, and denial of access to medical facilities and physician back-up services. The successful judicial challenges to discriminatory practices against other allied health care providers will be explored as a solution to the nurse practitioners' dilemma.
