The enrollment moratorium in Houston has been in place for a year and a half, and the ban in Philadelphia has been in place for a year. Both enrollment freezes will now extend into the summer of 2015, unless CMS decides to lift them. They apply to newly enrolling ground ambulance suppliers in these regions. The enrollment freezes do not affect enrollment-related changes that current suppliers need to make regarding practice locations, addresses and ownership, and they do not affect revalidations.
The Affordable Care Act (ACA) gave CMS the authority to impose a temporary moratorium on the enrollment of new Medicare, Medicaid or CHIP providers and suppliers if CMS determines a moratorium is necessary to combat fraud, waste or abuse. Each time CMS has exercised this authority, it has targeted ground ambulance suppliers.
