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, group health plans (excluding small group plans) must include coverage for standard fertility preservation services, which encompasses two completed oocyte retrievals with unlimited embryo transfers, following the guidelines set by the American Society for Reproductive Medicine. By January 1, 2026, these plans must also cover the diagnosis and treatment of infertility under similar terms. The bill aims to improve access to fertility services, reduce disparities in care, and enhance health outcomes for families.

Additionally, the bill prohibits health plans from imposing any exclusions, limitations, or restrictions on fertility medications and services that differ from those applied to other prescription medications. It also ensures that benefits for infertility diagnosis and treatment are provided to enrollees and their dependents on par with other pregnancy-related benefits. The bill includes definitions for infertility and standard fertility preservation services, aligning them with established medical practices. The act is referred to as the "Washington State Building Families Act," and the insurance commissioner is authorized to adopt rules for its implementation and enforcement.
