Comprehensive Error Rate Testing (CERT)


Centers for Medicare & Medicaid Services (CMS) established the Comprehensive Error Rate Testing (CERT) program to monitor and report the accuracy of Medicare fee-for-service (FFS) payments. The CERT program measures the error rate for claims submitted to Medicare contractors. Palmetto GBA uses CERT reports to identify areas of focus for our Provider Outreach and Education efforts. One of the major outcomes of these CERT reports is the paid claims error rate (percentage of dollars paid incorrectly).

From this web page, you may view CERT error rates by code group and provider type (specialty), articles about specific areas of concern as a result of CERT review findings, and newsletters from the CERT documentation contractor (CERT DC).
