The proposed bill aims to enhance access to infertility diagnosis, treatment, and standard fertility preservation services in Washington State. It mandates that group health plans, health plans for state employees, and Medicaid coverage include these services, with specific implementation timelines starting from January 1, 2026, for fertility preservation and January 1, 2027, for infertility diagnosis and treatment. The bill stipulates that coverage must include two completed oocyte retrievals with unlimited embryo transfers, aligning with guidelines from the American Society for Reproductive Medicine. Additionally, it prohibits any discriminatory exclusions or limitations on fertility medications and services compared to other medical benefits.

The legislation also defines key terms related to infertility and fertility preservation, ensuring that the benefits are provided to enrollees and their dependents similarly to other pregnancy-related benefits. The bill emphasizes the importance of reducing disparities in access to care, particularly for racial and ethnic minorities and LGBTQ individuals. Furthermore, it allows the insurance commissioner to adopt rules for the implementation and enforcement of these provisions, and it is officially titled the "Washington State Building Families Act."
