The "Patient Matching And Transparency in Certified Health IT Act of 2025" (MATCH IT Act of 2025) addresses the critical issue of patient misidentification within the U.S. healthcare system. Congress finds that inaccurate patient matching leads to significant medical errors, privacy breaches, and substantial unnecessary costs, estimated at over $6.7 billion annually for the healthcare system. This legislation seeks to promote interoperability and protect patients by establishing comprehensive standards and protocols to improve the accuracy of patient matching. To achieve this, the bill directs the Secretary of Health and Human Services to establish a uniform definition and standards for "patient match rate" within 180 days, accounting for issues like duplicate and overlaid records. Concurrently, the National Coordinator for Health Information Technology must identify and adopt a minimum data set into the United States Core Data for Interoperability within 180 days, aiming to support a 99.9% patient matching rate. Both initiatives require extensive consultation with healthcare providers, technology vendors, patient groups, and various federal agencies. Furthermore, the bill mandates that this minimum data set be incorporated into health IT certification requirements within 180 days of its finalization. Within 24 months, the Secretary must also integrate these standards into Medicare program requirements to promote interoperability. Finally, the Centers for Medicare and Medicaid Services will establish a voluntary bonus measure within the Medicare Promoting Interoperability Program, incentivizing eligible providers who achieve at least a 90% accurate patient match rate through anonymous reporting.
