Attention: Phishing Fax Requests

Please be aware of this important CMS noticeExternal Website in response to questions and concerns about suspicious faxes:

Alert: Medicare Fraud Scheme Involving Phishing Fax Requests

CMS has identified a fraud scheme targeting Medicare providers and suppliers. Scammers are impersonating CMS and sending phishing fax requests for medical records and documentation, falsely claiming to be part of a Medicare audit.

Important: CMS doesn't initiate audits by requesting medical records via fax. Protect your information. If you receive a suspicious request, don't respond. If you think you got a fraudulent or questionable request, work with your Medical Review ContractorExternal website to confirm if it's real.

Additional Information

To confirm if a request is valid, we encourage you to reference the websites below for details about each Medical Review Contractor's specific additional documentation request process (including sample letters in some cases). If you still have questions, please use the contact information to reach out.
