GPO's receive subpoenas from Dallas' U.S. Attorney.

This is going to be huge.

Novation, one of the largest group purchasing organizations (GPO's) in the country ($20 billion a year in sales), has been served with subpoenas signed by the chief of the criminal division of the U.S. Attorney's office in Dallas, according to an article in Saturday's N.Y. Times. It's part of a much larger investigation into the way medical supplies are purchased, sold to hospitals, and billed to federal health programs like Medicare. Novation is owned by, and sells to, some of the largest and most prestigious nonprofit health care centers in the country, who in turn bill Medicare. Ultimately, the investigation will be looking into the hospitals' billing practices.
