CMS's Internet-based Provider Enrollment, Chain and Ownership System (PECOS) will be offline for scheduled maintenance from Wednesday, Sept. 29 through Sunday, Oct. 3.
By our count, this is the second time PECOS will be out for maintenance this year. But many Medicare providers reported PECOS was virtually paralyzed at times over the summer as the online enrollment site was overwhelmed with visitor traffic.
While PECOS is out, CMS suggests you wait for it to go back online on Oct. 4 or complete the paper enrollment application. If you need assistance or have questions, CMS suggests you contact the Medicare fee-for-service contractor serving your state.
