All Fiscal Intermediaries, Carriers and Part A/B Medicare Administrative Contractors have been requested by the Centers for Medicare and Medicaid Services (CMS) to begin a provider enrollment revalidation effort, which is consistent with the Federal Regulations found at 42 CFR 424.500 and the Program Integrity Manual Chapter 10, Section 9. This effort will focus on the top 100 billers for each contractor.

The revalidation process is designed to ensure that CMS maintains uniform and up-to-date information on all providers and suppliers who are submitting claims to Medicare for services rendered to Medicare beneficiaries and will ensure that each contractor establishes a one-to-one match for each Medicare Legacy Identifier/National Provider Identifier billing combination.

If you are one of the top 100 billers identified a revalidation request letter will be mailed to you no later than September 30, 2007. You will have 60-days from the postmark date on the letter to respond by submitting a complete and accurate CMS 855 application, along with all of the applicable supporting documentation, including the Electronic Funds Transfer Authorization Agreement. Failure to submit the requested revalidation information will result in the revocation of your enrollment and Medicare billing privileges.
