The Centers for Medicare & Medicaid Services (CMS) has become aware of a scam where perpetrators are sending faxes to physician offices posing as the Medicare carrier or Medicare Administrative Contractor (MAC). The fax instructs physician staff to respond to a questionnaire to provide an account information update within 48 hours in order to prevent a gap in Medicare payments. The fax may have the CMS logo and/or the contractor logo to enhance the appearance of authenticity.
