What does Texas SB1257 do?
SB1257 creates a mandatory benefit for gender transition reversals, reconstruction, and the treatment of adverse effects for any Texas-regulated health plan that covers—or has ever covered—gender transition procedures. This legislation imposes "long-tail" liability on fully insured carriers and non-ERISA plans (such as school districts and local governments), requiring them to cover "detransition" services and anatomy-based screenings regardless of gender markers, effective for plan years beginning January 1, 2026. Implementation Timeline Effective Date: September 1, 2025 (The Act enters the Insurance Code).
