This bill aims to strengthen the World Trade Center Health Program (WTCHP) by addressing its funding, administrative flexibility, and long-term planning. A primary objective is to ensure the program's financial viability through significant adjustments to its funding mechanism, extending through 2090. A key provision modifies the WTCHP's funding formula for fiscal years 2026 through 2090, introducing an annual increase factor of 1.07 multiplied by a ratio reflecting changes in program enrollment. This aims to better align funding with the program's evolving needs over several decades. For fiscal year 2026, specific funding categories will receive the greater of their previously determined amount or the prior year's expenditure increased by 25 percent. The bill also enhances flexibility for mental health care within the program by permitting licensed mental health providers , in addition to physicians, to conduct initial health evaluations and make certifications for mental health conditions. The WTC Program Administrator is tasked with issuing regulations to define the categories of these qualified mental health providers. Additionally, it clarifies enrollment calculations by explicitly excluding deceased individuals from program counts for both responders and survivors. Furthermore, the timeframe for the Administrator to add new health conditions to the list for WTC responders is extended from 90 to 180 days. Finally, the legislation mandates a comprehensive report from the Secretary of Health and Human Services to Congress within three years, assessing the WTCHP's anticipated budget authority and outlays through 2090 and recommending potential changes to the funding formula.
