•New physicians, practitioners, and suppliers can sign the participation agreement and become a Medicare participant at the time of their enrollment into the Medicare Program. The participation agreement will become effective on the date of filing; i.e., the date the participant mails (post-mark date) the agreement to the carrier or delivers it to the carrier.
Contact your MAC/carrier to get the exact dates the participation agreement will be accepted, and to learn where to send the agreement.
WHAT TO DO DURING OPEN ENROLLMENT:
If you choose to be a participant:
•Do nothing if you are currently participating, or
•If you are not currently a Medicare participant, complete the blank agreement (CMS-460) and mail it (or a copy) to each carrier to which you submit Part B claims. (On the form show the name(s) and identification number(s) under which you bill.)
If you decide not to participate:
•Do nothing if you are currently not participating, or
•If you are currently a participant, write to each carrier to which you submit claims, advising of your termination effective the first day of the next calendar year. This written notice must be postmarked prior to the end of the current calendar year.
WHAT TO DO IF YOU’RE A NEW PHYSICIAN, PRACTITIONER OR SUPPLIER:
If you choose to be a participant:
•Complete the blank agreement (CMS-460) and submit it with your Medicare enrollment application to your MAC/carrier.
•If you have already enrolled in the Medicare program, you have 90 days from when you are enrolled to decide if you want to participate. If you decide to participate within this 90-day timeframe, complete the CMS-460 and send to your MAC/carrier.
If you decide not to participate:
•Do nothing. All new physicians, practitioners, and suppliers that are newly enrolled are automatically non-participating. You are not considered to be participating unless you submit the CMS-460 form to your MAC/carrier.
We hope you will decide to be a Medicare participant.
Please call the MAC/carrier in your jurisdiction if you have any questions or need further information on participation.
DO NOT SEND YOUR CMS-460 FORM TO CMS, SEND TO YOUR MAC/CARRIER. IF YOU SEND YOUR FORMS TO CMS, IT WILL DELAY PROCESSING OF YOUR CMS-460 FORMS.
