Repeals a provision of law relating to state-based health benefit exchanges

HB 3136 restricts Missouri's ability to operate a state-run health insurance marketplace (often called a "health exchange" under federal law). It requires specific legislative approval - via bill, initiative, or referendum - before any state agency can establish, administer, or fund such a marketplace, banning executive orders or informal actions. The bill also prohibits state entities from using federal funds for these exchanges without explicit authorization and blocks agreements with federal authorities to create or operate a federal-facilitated exchange. This directly affects Missouri state departments, agencies, and political subdivisions that might otherwise engage with the federal health care law's marketplace system.
