The proposed bill mandates that health plans in Washington State provide coverage for the diagnosis and treatment of infertility, as well as standard fertility preservation services, effective January 1, 2025. This coverage must be extended to enrollees, including their spouses and nonspouse dependents, on par with other pregnancy-related benefits. Specifically, the bill stipulates that health plans must cover four completed oocyte retrievals with unlimited embryo transfers, adhering to guidelines from the American Society for Reproductive Medicine. Additionally, the bill prohibits any exclusions or limitations on fertility medications that differ from those for other prescription drugs, as well as any restrictions based on participation in third-party fertility services.

Furthermore, the bill defines key terms related to infertility and outlines the conditions under which the state may be required to defray costs for individual or small group health plans. It emphasizes the importance of increasing access to infertility treatment to improve health outcomes for mothers and children, while also addressing disparities in care for racial and ethnic minorities and LGBTQ individuals. The act is officially titled the "Washington State Building Families Act."
