This article originally offered a January 6, 2011 provider list. That historical file cannot establish current enrollment. Use the PECOS enrollment record lookup to search a more recent CMS public dataset by NPI and see its source period. A match does not confirm current billing privileges; no match does not establish that a provider is unenrolled.
For current status, contact your Medicare Administrative Contractor. For application steps, read our PECOS enrollment guide and document checklist.
Please let us know if you have any questions about PECOS or need assistance with your PECOS application.
