Yesterday evening, CMS issued an emergency update to the CY 2011 Medicare Physician Fee Schedule (MPFS) database in the form of this transmittal.  Through this transmittal, CMS accepted the arguments of the radiation oncology community, including ACRO, that the work RVUs for 77427 should be 3.37. 

Also of importance, the transmittal establishes the new conversion factor for 2011 - $33.9764 - based on the zero percent update contained in the Medicare and Medicaid Extenders Act of 2010 and other changes contained in the update.  In addition, due to the budget neutral nature of changes to the PFS RVUs contained in the update, CY 2011 RVUs will change slightly in most cases relative to the CY 2011 PFS Final Rule.  The agency has issued related payment files here which contain the revised RVUs.
