At the time of the original publication of CodeManager 2012 Q1, the only available 2012 Physician Fee Schedule data was the CMS information published November 14, 2011.
Congress subsequently passed legislation that updated the Physician Fee Schedule and made the change retroactive to January 1, 2012. The patch updates CodeManager 2012 Q1 to use the updated information published January 3, 2012 that is effective January 1 - February 29, 2012.
