Q: What is the purpose of the Medicare Participating Physician or Supplier Agreement (CMS-460)?
A: New physicians, practitioners, and suppliers may submit the
CMS-460 form 
at the time of their enrollment. Participants agree to accept assignment for all covered services provided to Medicare patients.
In addition, the CMS-460 may also be used for existing providers during the annual participation open enrollment. The annual physician and supplier participation period begins January 1 of each year, and runs through December 31. The annual participation enrollment is scheduled to begin on November 15 of each year. (Note: The dates listed for release of the participation enrollment/fee disclosure material are subject to publication of the annual Final Rule.)
During the annual enrollment period, for First Coast, the MAC for jurisdiction N (JN), which includes Florida, Puerto Rico, and the U.S. Virgin Islands, submit your completed CMS-460 form (or disenrollment request) to:
