On December 23, 2011, CMS issued an informational bulletin on the Medicare, Medicaid, and CHIP provider screening and enrollment provisions in Section 6401 of the ACA. The bulletin addresses procedures for state compliance with the ACA mandate, and includes answers to frequently-asked questions regarding, among other things: the screening process timeline, collection and processing of enhanced provider enrollment/screening information, application fees, the revalidation process, enrollment for ordering and/or referring providers, and moratoria on provider enrollment.  For background information on the ACA screening requirements and implementing regulations, see our previous report.
