CMS is hosting a conference call on Tuesday, August 12, 2014 to discuss its planned expansion of its current demonstration project testing a prior authorization (PA) process for Medicare power mobility device claims.  This demonstration was launched on September 1, 2012 in seven states with what CMS describes as “high populations of fraud- and error-prone providers” – California, Illinois, Michigan, New York, North Carolina, Florida, and Texas.  CMS now seeks to extend the program to 12 additional states beginning October 1, 2014: Pennsylvania, Ohio, Louisiana, Missouri, Maryland, New Jersey, Indiana, Kentucky, Georgia, Tennessee, Washington, and Arizona.  The CMS call is intended to provide an opportunity for suppliers and providers to receive information and ask questions about the expanded demonstration.
