Concerning the diabetes prevention and obesity treatment act.

SB 5353 requires Washington health insurance plans to cover obesity treatment as a chronic condition starting January 1, 2026. It mandates coverage for three specific treatments: intensive behavioral/lifestyle programs, metabolic/bariatric surgery, and FDA-approved obesity medications. The bill prohibits insurers from imposing stricter coverage rules for obesity than for other medical conditions, ensuring equal treatment for deductibles, copays, and annual limits. This directly affects health insurers and people diagnosed with obesity in Washington state. The law aligns with FDA-approved treatments and clinical guidelines, defining covered services to prevent discriminatory coverage practices.
