CMS published a revision to Implementation of a Prospective Payment System (PPS) for Federally Qualified Health Centers (FQHCs). Except for services that are paid at 100 percent of costs, Medicare currently pays FQHCs 80 percent of their AIR.  MACs reconcile costs and visits at year-end through cost report settlement. In compliance with the statutory requirements of the Affordable Care Act, CMS established a national encounter-based prospective payment rate for all FQHCs, determined based on an average of the reasonable costs of all FQHCs. FQHCs will transition to the FQHC PPS based on their cost reporting periods. For FQHCs with cost reporting periods beginning before October 1, 2014, MACs shall continue to pay the FQHCs using the current AIR system.  For FQHCs with cost reporting periods beginning on or after October 1, 2014, MACs shall pay the FQHCs using the FQHC PPS.
