The U.S. Army has launched a system-wide review to ensure its healthcare providers are not considering treatment costs when they make diagnoses. The review comes after it was revealed therapists at Madigan Army Medical Center in Washington state reversed diagnoses of post-traumatic stress disorder for hundreds of soldiers. The center is located at Joint Base Lewis-McChord, the home base of Staff Sgt. Robert Bales, who is suspected of killing 16 Afghan villagers earlier this month. Data released by Washington Sen. Patty Murray shows a Madigan screening team reversed more than 40 percent of PTSD diagnoses for patients being considered for medical retirement since 2007.
