WA HB1129

Group health plans (excluding small group plans) must cover standard fertility preservation services starting January 1, 2026, and infertility diagnosis and treatment starting January 1, 2027

Infertility treatment coverage must include two completed oocyte retrievals with unlimited embryo transfers, following American Society for Reproductive Medicine guidelines with single embryo transfer when medically appropriate

State employee health plans and Medicaid must also provide coverage for fertility preservation services under the same timeline and restrictions

Plans cannot impose different exclusions, limitations, deductibles, copayments, or waiting periods on fertility services than those applied to other medical services or prescription medications

"Infertility" is broadly defined to include failure to establish pregnancy after 12 months of unprotected intercourse (6 months for women 35+), inability to reproduce without medical intervention, or physician findings based on medical history and diagnostic testing
