Senate Bill 566 mandates that health insurance policies and self-insured governmental health plans that cover medical or hospital expenses must provide coverage for the diagnosis and treatment of infertility, as well as standard fertility preservation services. The bill specifies that coverage must include at least four completed egg retrievals with unlimited embryo transfers, and allows for single embryo transfers when deemed medically appropriate. Additionally, the bill prohibits policies and plans from imposing any exclusions, limitations, or restrictions on medications or services related to infertility that are not applied to other prescription medications or services covered under the policy.

The bill also establishes definitions for infertility and standard fertility preservation services, and outlines the responsibilities of the commissioner to create necessary rules for implementation. It ensures that covered individuals, including spouses and dependents, receive infertility treatment benefits comparable to other pregnancy-related benefits. The act will take effect four months after publication and will apply to policy or plan years beginning on the effective date, with specific provisions for collective bargaining agreements.
