On December 21, 2011, CMS is hosting a special open door forum provider call on its Medicare Fee-For-Service Recovery Auditor Prepayment Review Demonstration, which will expand the use of Medicare Recovery Auditors in the Medicare fee-for-service program to review claims before they are paid. This demonstration will focus on seven states with high populations of what CMS characterizes as “fraud-and error-prone providers” (FL, CA, MI, TX, NY, LA, IL), along with four states with high volumes of claims for short inpatient hospital stays (PA, OH, NC, MO).
