Mississippi uses the federal Marketplace, not a state exchange
Mississippi does not run its own health insurance exchange. Marketplace plans for Jackson residents are sold through the federal HealthCare.gov platform, which means the enrollment windows, subsidy rules, and plan metal tiers are the federal ones. Working with a licensed broker does not change your price — carriers file the same rates whether you enroll on your own or with help.
What a broker changes is the process. Samuel is appointed with the carriers selling on the Mississippi exchange, so he can line up their networks, deductibles, and drug lists side by side instead of leaving you to sort through them alone on the federal site.
