CERT stands for what?

• A. A routine internal audit method in clinics
• B. Certified Error Rate Tool used by MACs
• C. Comprehensive Error Rate Testing program instituted by CMS to monitor and calculate the accuracy and error rates for all MACs and to monitor the accuracy of Medicare payments to FIs, carriers, and DMERCs
• D. Certification of Electronic Records Testing

Answer: (C)

Comprehensive Error Rate Testing is a CMS program designed to estimate improper Medicare payments by sampling paid claims across Medicare Administrative Contractors (MACs), Fiscal Intermediaries (FIs), Durable Medical Equipment Medicare Contractors (DMERCs), and carriers. It measures the accuracy of payments and calculates an overall error rate, which helps CMS monitor payment integrity and identify areas for improvement. This description fits the option because it explicitly names the program and its purpose—monitoring the accuracy of Medicare payments to these entities. The other choices describe concepts that don’t reflect what CERT is: it isn’t a routine internal clinic audit method, it isn’t a tool called the Certified Error Rate Tool used by MACs, and it isn’t Certification of Electronic Records Testing.
