BOISE, Idaho -

Idaho Attorney General Lawrence Wasden has agreed not to sue St. Luke's Health System for purchasing the assets of a Boise rehabilitation hospital as long as St. Luke's limits its contracts with some rehabilitation physicians.

The Idaho Statesman reports Wasden's office raised concerns this spring that the purchase could give St. Luke's an unfair advantage if St. Luke's controlled where the rehabilitation doctors refer their patients.

Under the agreement, Wasden won't investigate St. Luke's purchase of many of the assets of Idaho Elks Rehabilitation Hospital. In exchange, for the next two years, St. Luke's won't contract for more than 50 percent of the services provided by Boise Physical Medicine and Rehabilitation. That medical group includes doctors who practice at Elks, St. Luke's and Saint Alphonsus Health System Hospitals.
