Waterloo, Iowa-based VGM Group has postponed its series, "Competitive Bidding Round 1.2: The Rules Have Changed," originally scheduled to begin in March. The nine sessions, which were planned throughout the country this spring, have been put on hold because of a delay in the competitive bidding interim final rule until April 18.

VGM will present the seminar in Las Vegas during Medtrade Spring March 24 and again in Baltimore April 22.
