This bill, known as the "Access to Pediatric Technologies Act of 2025," aims to facilitate patient access to certain pediatric medical devices by amending Title XVIII of the Social Security Act. It mandates the Secretary to establish national relative value units (RVUs) for "qualifying pediatric technologies" under the Medicare physician fee schedule. This process will be initiated upon a manufacturer's written request for technologies furnished on or after January 1, 2026, ensuring appropriate payment mechanisms are in place where none currently exist. A qualifying pediatric technology is defined as a Medicare-covered medical device that is FDA-approved, cleared, or authorized, described by a temporary HCPCS code, and either predominantly used in pediatric patients or specifically designed for them. Manufacturers must submit a request with relevant data, such as pricing information or claims data, to support the establishment of these RVUs. The Secretary will incorporate these into the annual rulemaking process for the physician fee schedule, with specific timelines for requests received before or after May 1. Importantly, this legislation focuses on establishing payment rates and does not require Medicare coverage for these technologies.
