Alert: Fraudulent Correspondence Targeting Medicare Providers

Noridian has been made aware of fraudulent letters being sent to providers. These notices instruct providers to fax sensitive information that the Centers for Medicare & Medicaid Services (CMS) already has on file. Please be advised that these letters are not legitimate.

CMS has been notified of this activity and is working to address the situation. To help protect your practice and patient data, please review the following commonly found in these fraudulent correspondences:

  • Generic Sender Information: The letter lists only "CMS" without an individual name or department. Legitimate CMS communications typically include specific contact details.
  • Incorrect Return Number: The return number provided is 1-800-MEDICARE, which is intended for beneficiary inquiries, not provider communications.
  • Unnecessary Requests for Existing Information: Medicare already has your enrollment details. CMS does not request providers to re-submit this information via fax.
  • Urgent or Threatening Language: Fraudulent letters often create a false sense of urgency to pressure providers into compliance.

If you receive any correspondence requesting sensitive information, verify its authenticity before responding. Contact Noridian or CMS directly using official contact channels. Do not use phone numbers or fax numbers provided in suspicious letters.
