WellStar Health System said a Supreme Court of Georgia ruling will allow it to add an ambulatory surgery center at its East Cobb Health Park.

WellStar sought a Certificate of Need from the Department of Community Health in 2010 to move three operating rooms from WellStar Windy Hill Hospital to the 162,000-square foot health park, which is scheduled to open in September. But adverse rulings by a Fulton County Superior Court judge and by the Georgia Court of Appeals stalled the project.

The CON process is intended to prevent costly duplication of services.

The ambulatory surgery center is to open about six months after the the health park does.

A WellStar executive said the facility will offer, “… a one-stop shop for a comprehensive array of outpatient medical services.”
