Enroll in or opt out of Medicare

January 01, 2019 1200

Dentists who order or provide Medicare-covered items and services (clinical laboratory services, imaging services or durable medical equipment, prosthetics, orthotics and supplies) will need to either enroll in Medicare using form CMS-855-I (PDF) or the shorter enrollment form CMS-855-O (PDF) or formally opt out of Medicare by Jan. 1, 2019. To assure one's status with Medicare and that patients' Medicare benefits do not lapse, dentists should allow sufficient time for processing whichever form is submitted.
