Provider Certification Denials


Denial Reason and Reason/Remark Code
CO-B7: This provider was not certified/eligible to be paid for this procedure/service on the date of service.

Resolution and Resources
Medicare contractors periodically turn off provider billing numbers after a period of inactivity. If your number has been deactivated for this reason:
  • Download the forms directly from the CMS website. Then complete, print, sign and mail to Palmetto GBA.
  • Complete and submit your application through PECOS website. Your application may be processed up to 50 percent faster than applications submitted on paper.
  • Not sure which form to complete? Access the Palmetto GBA provider enrollment web page for helpful tips.
