If a Medicare provider or supplier enrolled prior to March 25, 2011, they are required under the terms of the Affordable Care Act to revalidate their provider enrollment information. Providers and suppliers must wait to submit the revalidation until they receive notice from ther MAC to do so. Between now and March 23, 2013, MACs will send out notices on a regular basis to begin the revalidation process for each provider and supplier.

Newly enrolled providers and suppliers that submitted their enrollment applications to the Centers for Medicare & Medicaid Services (CMS) on or after March 25, 2011, are not required to revalidate.

When you receive notification from your MAC to revalidate you need to:

• Update your enrollment through Internet-based Provider Enrollment, Chain and Ownership System (PECOS) or complete the appropriate CMS-855 form

• Sign the certification statement on the application

• All institutional providers and suppliers who respond to a revalidation request mustsubmit an enrollment fee via Pay.Gov (reference 42 CFR 424.514). You may submit your fee by electronic check, debit, or credit card.

• Mail your supporting documents and certification statement to your MAC

Upon receipt of the revalidation request from their MAC, providers and suppliers have 60 days from the date of the letter to submit complete provider enrollment forms. Failure to submit the enrollment forms as requested may result in the deactivation of your Medicare billing privileges.
