How To Complete a Medicare Participating Physician or Supplier Agreement (CMS-460)
Upon receipt of a new Medicare provider number, a new Medicare provider has 90 days to submit a signed Medicare participating physician or supplier agreement (CMS-460) to the Medicare carrier or A/B Medicare Administrative Contractor (MAC). A participating provider enters into an agreement to accept the Medicare-approved amount as full payment for services and supplies covered under Part B. This agreement (CMS-460) renews automatically each year.

A change in name and/or EIN (tax identification number) is a change in identity and requires a new participation decision. A participating provider receives five percent more on reimbursement for physician-related services. Those who have not signed a participation agreement are listed as non-participating providers and are subject to the limiting charge fee schedule. The Medicare Participating Physician or Supplier Agreement (CMS-460) is available by clicking on the link below. Complete and mail the signed form to Palmetto GBA.
