This bill, the "Access to Pediatric Technologies Act of 2025," amends the Social Security Act to facilitate patient access to specialized medical devices. It requires the Secretary of Health and Human Services to establish national relative value units (RVUs) under the Medicare physician fee schedule for qualifying pediatric technologies that currently lack them. This process is initiated upon a manufacturer's request, ensuring appropriate payment rates are set for these innovative devices. A technology qualifies if it is covered by Medicare, FDA-approved, cleared, or authorized, and described by a temporary Level I HCPCS Code. Furthermore, it must be predominantly used on pediatric patients or specifically designed for their safe and effective use. Manufacturers must submit a written request with supporting data, and the Secretary will use existing payment methodologies and available information to establish the RVUs. This legislation aims to remove payment barriers for pediatric technologies without altering Medicare's coverage requirements.
