Now that Medicare revalidation is back in action, you may want to check and see when your number is up. The Centers for Medicare & Medicaid Services’ (CMS) Revalidation List webpage can be a little tricky, acknowledges HHH Medicare Administrative Contractor (MAC) National Government Services (NGS) on its website. After entering a National Provider Identifier (NPI) number, “the revalidation due date for each record is found to the right of the provider’s name,” NGS explains. Tip: A provider’s “due date will not be removed from the Medicare Revalidation List Tool during a five year revalidation cycle,” NGS offers. “The due date will continue to display on the website even after a provider has revalidated successfully.” To make things more confusing, a “provider may have more than one Medicare enrollment due to specialty type, type of enrollment or state,” NGS adds.
