About the CERT

• The objective of the CERT program is to monitor and report the accuracy of claims payment in the Medicare Fee-for-Service program.
• CMS uses the CERT error rate to evaluate the performance of the Medicare Administrative Contractors (MACs).
• There are two CERT contractors:
• The CERT Review Contractor (CERT RC), and
• CERT Statistical Contractor (CERT SC).
• The CERT claim selection includes a stratified random sample of approximately 50,000 claims that are chosen by claim type (Part A, Part B and Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS), and includes paid and denied claims by the MAC.
• The CERT process is a federally mandated program and not responding to documentation requests will result in a denial of all services billed on the claim.
• CERT request letters are mailed to the correspondence address listed in the Provider Enrollment, Change and Ownership System (PECOS).
• You can submit requested documentation to the CERT via postal mail, fax, Electronic Submissions of Medical Documentation (esMD), via CD or via email attachment(s).
• For short (less than 24 – 48 hours stay) inpatient hospital stay, a discharge summary is not required when a beneficiary is seen for minor problems or interventions, as defined by the medical staff. In this instance, a final progress note may be substituted for the discharge summary.
• The billing provider is responsible for obtaining medical records from the third-party to substantiate the claim that was billed.
• The CERT makes every effort to obtain the request documentation. Providers have 45 days to respond to the first letter requesting documentation. When the CERT does not receive the requested documentation by the 75th day, a claim is counted as a non-response error and is subject to overpayment recovery by the MAC.
• Claims reviews by the CERT includes program checks for compliance with Medicare statutes and regulations, billing instructions, National Coverage Determinations (NDCs), Local Coverage Determinations (LCDs), Local Coverage Articles (LCAs), and provision in the CMS instructional manuals.
• Denied claims as well as overpayments and underpayments are all considered to be an improper payment by the CERT program.
• Improper payments are attributed to one of five major error categories (no documentation, insufficient documentation, medical necessity, incorrect coding, or other).
• The improper payment rate is not a “fraud rate,” but a measurement of payments that did not meet Medicare requirements.
• Providers that wish to appeal a CERT contractor’s determination can follow the normal redetermination process to appeal all CERT denials.
• The CERT A/B MAC Outreach & Education Task Force has a goal to ensure consistent communication and education to reduce the Medicare Part A and Part B error rates. The Task Force webpage (link) includes education resources for providers.
