Concerning contraceptive coverage.

HB 1090 requires health benefit plans in Washington State (effective January 1, 2026) to cover a 12-month supply of contraceptive drugs at one time, rather than requiring multiple refills. This directly affects health insurers and enrollees, mandating that plans provide this coverage unless an enrollee or provider requests a smaller supply. Key provisions include allowing on-site dispensing at providers' offices (when available) and requiring plans to follow clinical guidelines for appropriate prescribing. The bill defines "contraceptive drugs" to include all FDA-approved pregnancy prevention medications, such as oral, transdermal, and intravaginal hormonal drugs.
