2019 Open Enrollment Period

The 2019 Annual Participation Open Enrollment Period is approaching and runs mid-November through December 31, 2018. The open enrollment period allows Medicare suppliers to revisit their choice to accept Medicare assignment for claims payment. The participation status only affects how you are reimbursed from Medicare. Changing your status to non-participating does not terminate your Medicare billing privileges.

  • Do nothing if you do not wish to change your participation status 
  • To change your status to participating, submit a request on the CMS-460 form signed by the authorized or delegated official as previously reported to the NSC 
  • To change your status to non-participating, submit a request on your company's letterhead signed by the company's authorized or delegated official as previously reported to the NSC

The CMS-460 participation agreement can be downloaded from the CMS website (PDF, 217 KB).

Remember, if you do not wish to make any changes to your participation status, it is not necessary to respond during this period. Please Note: If you are currently enrolled in the Medicare program other than as a DMEPOS supplier, you may only change your participation status with one contractor. Participation status will be the same with all Medicare contractors. Medicare DMEPOS Fee Schedules for services rendered during 2019 will be posted on your DME MAC’s website.

We hope you will decide to be a Medicare participant. For more information, contact NSC Customer Service at 866-238-9652, Monday through Friday, 9:00 am to 5:00 pm, ET.
