Systematic Synchronization of Medicare Participating Physician or Supplier Agreement (PAR) Status Between the Multi Carrier System (MCS) Provider Enrollment, Chain and Ownership System (PECOS)

Since contractors are able to directly input the provider/supplier PAR status into MCS with the use of Action Reason Code (AR) 03, a number of PAR eligible providers/suppliers are missing the PAR Status indicator in the PECOS. To synchronize PECOS with MCS, CMS will perform a data exchange between MCS and PECOS to ensure both systems are synchronized with the most current PAR information.
