PECOS (Provider Enrollment and Chain/Ownership System) is the electronic portal through which physicians enroll in Medicare. Some Medicare-enrolled physicians do not have current records in PECOS because they have not submitted any enrollment information updates to Medicare since November 2003.
Use this search to determine if you have registered with the Centers for Medicare & Medicaid Services (CMS) PECOS program.
**NOTE: PECOS does not include physician nicknames. Example - Robert Smith, MD practicing as Bob Smith, MD, will be in PECOS as Robert Smith, MD**
CMS will instruct contractors to turn on Phase 2 denial edits on January 6, 2014. [Read More]
CMS updates the data file for PECOS once a week and the results showing are from the most recent file update. This is based on a CMS data file and, therefore, is not warranted or guaranteed.
