State and federal regulations require all currently enrolled Medicaid providers to revalidate their enrollment at least every five (5) years.  MMAC has established a revalidation schedule for all currently enrolled providers.  MMAC will contact currently enrolled providers approximately 120 days prior to their scheduled revalidation due date.  Instructions and forms will be provided by mail or e-mail.  More information on revalidation is available under the Providers tab here on our website.  Under the Providers tab, choose Provider Enrollment, and Revalidating Providers.
