Concerning health plan coverage of fertility-related services.

HB 1129 requires most group health plans in Washington to cover fertility preservation services starting January 2026 and infertility diagnosis/treatment starting January 2027. It mandates coverage for two egg retrieval procedures with unlimited embryo transfers (per medical guidelines), prohibits different cost-sharing for fertility services compared to other pregnancy care, and ensures coverage extends to spouses and nonspouse dependents equally. The bill directly affects health insurers and enrollees seeking fertility care, including LGBTQ+ individuals and racial/ethnic minorities who face coverage disparities. Key provisions include banning restrictions on fertility medications and eliminating separate deductibles or waiting periods for these services.
