Physicians and Non-Physician Practitioners: New Medicare Enrollment Application

CMS received approval for a new Medicare Enrollment Application for physicians and non-physician practitioners (CMS-855I dated 12/2018). Many changes are minor; the major ones reduce provider burden:

  • Eliminated reporting for advanced diagnostic imaging, Clinical Laboratory Improvement Amendments number, and the Food and Drug Administration radiology certification number
  • Expanded instructions for individual and group affiliations to simplify reporting
  • Made it optional to list a contact person
  • Added electronic storage information for those who no longer keep paper records
  • Created a more logical data flow

You may begin using the new application immediately. Through April 30, Medicare Administrative Contractors will accept applications dated 7/2011, but after that, you have to use the new version.
