The warning states to check with your contractor, either than or throw it away. You can check the fax number as well for it’s origin to verify as well. BD
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.
Medicare FFS providers, including physicians, non-physician practitioners, should be wary of this type of request. If you receive a request for information in the manner described above, please check with your contractor before submitting any information. Medicare providers should only send information to a Medicare contractor using the address found in the download section of the CMS.gov website found at http://www.cms.hhs.gov/MLNGenInfo/ or http://www.cms.hhs.gov/MedicareProviderSupEnroll.
