Noridian, Medicare’s administrative contractor for California, reports that only 19 percent of physicians have responded to the most recent Medicare Part B revalidation notices. Noridian is in the process of deactivating Medicare billing privileges for physicians who received a revalidation notice from Noridian but did not turn in a completed application to the Centers for Medicare and Medicaid Services (CMS) prior to the most recent deadline of May 31. 

If you are deactivated for failure to respond to a revalidation notice, you must submit a reactivation application. The date of receipt of the reactivation application will be the new effective date for your Medicare billing privileges. Noridian will not apply a retroactive effective date and no payments will be made for the period of deactivation.

If a revalidation application is received but incomplete, Noridian will contact you for the missing information. If the missing information is not received within 30 days of the request, Noridian will deactivate your billing privileges.

If your revalidation application is approved, no further action is needed.

If you do not know when you are up for revalidation, you can look up your revalidation date through the CMS look-up tool. Those due for revalidation in the near future will display a revalidation due date. All other providers/suppliers will see ""TBD"" in the due date field.

For more information on the revalidation process, see MLN Matters #SE1605.
