Comprehensive Error Rate Testing (CERT)

Since 1996, CMS implemented several initiatives to prevent improper payments. CMS' goal is to reduce payment errors by identifying and addressing billing errors concerning coverage and coding. The CERT is one of the programs created by CMS to assist in eliminating improper payments.

AdvanceMed is the CERT Review Contractor and the CERT Documentation Contractor. They complete audits on randomly selected claims submitted to Noridian. When a claim has been selected for an audit, AdvanceMed sends a supplier a Medical Record Request Letter asking that all supporting claim documentation be pulled for the audit.
