MANAGED CARE
Idaho Cardiology Assocs. v. Idaho Physicians Network, Inc., No. 30365 (Idaho Feb. 22, 2005)
 A physician group filed suit against a corporation that marketed
  the services of medical groups to insurance companies after the corporation
  refused to admit the physician group into its network. The physician group
  argued that the corporation was subject to the "any willing provider" statute,
  which requires any managed care organization issuing benefits to enter into care
  agreements with all qualified providers to provide certain health care services.
  The court held that since the corporation was an integral and inseparable part
  of a managed care organization, it was subject to the requirements of the any
  willing provider statute and, as a result, was statutorily obligated at all times
  to enter into care provider service agreements with all qualified providers such
  as the physician group.
