Creates provisions relating to insurance coverage of genetic screenings for cancer risk

HB 1879 requires Missouri health insurance plans to cover genetic counseling and genetic testing for cancer risk starting January 1, 2027. It applies to individuals assessed as high-risk for harmful gene mutations based on personal or family cancer history. The law mandates that coverage includes all associated costs with no deductibles, copays, or other cost-sharing, and prohibits insurers from using genetic test results to deny coverage, adjust premiums, or limit benefits. This policy directly affects Missourians seeking cancer risk assessment and their health insurers.
