Concerning the diabetes prevention and obesity treatment act.

HB 1326 requires health insurance plans in Washington State to cover obesity treatment starting January 1, 2026. It mandates coverage for three specific treatments: intensive behavioral therapy (including telemedicine), metabolic/bariatric surgery, and FDA-approved obesity medications. The law prohibits insurers from applying stricter coverage rules for obesity than for other medical conditions, ensuring equal treatment for deductibles, copays, and annual limits. This applies to all health plans issued or renewed in Washington, directly affecting millions of Washingtonians with obesity who rely on insurance for these treatments.
