PECOS Lookup
Find NPI numbers enrolled in Medicare

PECOS is the online Medicare enrollment management system or Provider, Enrollment, Chain and Ownership System. The PECOS system is a database of providers who have registered with CMS as Medicare providers or suppliers. The system allows providers the ability to renew Medicare enrollment and withdrawals, update provider information, report enrollment record changes, and the ability to electronically sign and submit information. The PECOS program was developed by the Centers for Medicare & Medicaid Services (CMS) after the Patient Protection and Affordable Care Act was approved.

Providers that want to participate in the Medicare program need to enroll in PECOS with their NPI to avoid denied claims.

Find the PECOS enrollment status of any NPI number with this fast and free PECOS Lookup tool. Search the complete NPI registry by:

• NPI Number
• Physician First Name or Last Name
• Organization Name

This tool is made available based on a CMS data file from November 24, 2023. The information is not warranted or guaranteed. If you have questions about your PECOS status or you need more information visit the CMS PECOS website.

As a healthcare provider your first step is to contact CMS directly or your Medicare Administrative Contractor (MAC) and obtain an enrollment application. Once your application is submitted use the PECOS system to follow up on your application status and to update your information like name, credentials, practice location, etc.
