Calendar Year (CY) 2026 Open Enrollment Period


The 2026 (CY) Annual Participation Open Enrollment Period is approaching and runs mid-November through December 31, 2025. 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 to non-participating does not terminate your Medicare billing privileges.

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

Remember, if you do not wish to make any changes to the participation status, it is not necessary to respond during this period.

Please Note: If currently enrolled in the Medicare program as something other than as a DMEPOS supplier, you may only change the participation status with one contractor. Participation status will be the same with all Medicare contractors. Medicare DMEPOS Fee Schedules for services will be posted on your DME MAC’s website.

For more information, please read CMS’ Participation Announcement or contact the NPWest Customer Service at 866-238-9652, Monday through Friday, 10:00 am to 6:00 pm, ET. 

For supplier convenience, responses to the open enrollment can now be directly uploaded to the NPWest by utilizing the NPWest Web Form Submission tool located under Forms/Tools on the NPWest website. Just follow the instructions and your participation documentation will be uploaded directly into our system for processing. No mailing required.
