Which system controls CPT code pairs that can be reported on the same day?

The National Correct Coding Initiative (NCCI) is the system responsible for controlling the specific pairs of CPT codes that can be reported together on the same day. NCCI is designed to promote correct coding methodologies and to prevent improper coding that can lead to inappropriate payments for services. It utilizes a series of edits that identify codes that should not be reported together due to their nature or relationship in treatment, thereby ensuring that billing is both accurate and compliant with regulations. This helps in preventing billing errors and fraud, contributing to the integrity of the healthcare reimbursement system.

The other options, while they refer to systems related to billing and coding, do not specifically function to evaluate and control the reporting of CPT code pairs in the way that NCCI does. Correct Billing Practices focuses on the overarching principles of correct billing; the Automated Claims Processing System pertains to the automation of claims submission and processing, and the Bundled Payments System relates to payment models rather than coding pair controls.
