On February 19, 2007 (but effective retroactively to January 26, 2007), the Centers for Medicare and Medicaid Services (CMS) rescinded the controversial IDTF transmittal referrenced in the February 18, 2007 entry on this Blog. A copy of the notice can be found here: Transmittal 187. Those guidelines would have imposed major new conditions on independent diagnostic testing facilities (IDTFs), and would have invalidated many leasing arrangements. No word yet as to whether CMS is planning to re-publish the guidelines any time soon. Stay tuned!
