Common CERT Errors

Noridian needs your help. To combat the national Comprehensive Error Rate Testing (CERT) error rate, we are asking associations, facilities and service providers to share this information with staff and affiliates, including compliance and business office management, physicians and practitioners, and all other individuals involved in patient care, coding, billing and medical record keeping. Together we can make a difference. View CERT Highlights.

Highlights

  • CMS implemented the CERT program to measure improper payments in the Medicare Fee-for-Service (FFS) program. CERT is designed to comply with the Improper Payments Information Act (IPIA) of 2002, as amended by the Improper Payments Elimination and Recovery Improvement Act (IPERIA) of 2012.
  • CERT is a requirement and mandated by law. Therefore, it is vital that all Medicare service providers are compliant with submitting the necessary information to support the coverage, coding and billing of services being submitted to Medicare for reimbursement.
  • Requests for records from the CERT Contractor do not pose any Health Insurance Portability and Accountability Act (HIPAA) vulnerabilities. Also, beneficiary authorization is not needed to release information for the request because authorization has already been given to release necessary medical information to process the claim.
  • A response to a CERT request for records is required even if records for the sampled beneficiary dates of service cannot be provided. In accordance with Social Security Act Sections 1156 [42 U.S.C. 1320C-5], 1833 [42 U.S.C. 13951](e), and 1815 [42 U.S.C. 1395g] (a), as a Medicare provider, documentation and medical records must be provided to the CERT contractor upon request to support claims for Medicare services. It is the billing providers responsibility to obtain additional supporting documentation from a third party (hospital, clinic, nursing home, etc.), as necessary. Providing medical records of Medicare patients to the CERT contractor is within the scope of compliance with the Health Insurance Portability and Accountability Act (HIPAA).
  • The Medicare FFS Supplemental Improper Payment Data for the 2017 report has been published on the CMS website. It will provide a lot of information that providers could use to identify error trends.
