Provider Revalidation Fact Sheet for Congressional Field Offices

The Affordable Care Act, Section 6401 (a), requires enrolled providers to revalidate their Medicare enrollment every five years, and enrolled DME suppliers to revalidate every three years. (Reference 42 CFR 424.515).

CMS began their second revalidation cycle in March 2016.

For each revalidation cycle:

  1. CMS will post the provider/supplier’s due date to revalidate on their Medicare Revalidation Lookup Tool at
  2. NGS will notify our providers and suppliers by letter when they are scheduled to revalidate. The letter received from us may include the following information:
    1. Due Date
    2. Provider Name
    3. NPI and PTAN combination
    4. Legal Business Name/DBA name
    5. State
    6. Tax ID (last four digits)

Note: The revalidation process does not change or alter normal provider enrollment laws for Medicare. If you have a change of address, reassignments, additions to practice, changes in authorized officials or other information updates you are still required to submit that change within 30 days. You cannot wait for revalidation to update your enrollment record; it is not in compliance with Medicare regulation.

Please see web link below for sample of the revalidation envelope:
