Delaware does not run its own exchange, so residents shopping for individual or family health coverage use HealthCare.gov, the federal marketplace, to compare plans and apply for premium tax credits.
Delaware has expanded Medicaid under the ACA, so adults earning up to 138% of the federal poverty level generally qualify for the state's Medicaid program rather than needing a subsidized marketplace plan.
Delaware's individual market is relatively small, with a limited number of insurers offering plans in most counties, so it's worth comparing available options early in the enrollment window rather than waiting, since choices can be more limited than in larger states. Checking whether a preferred hospital system participates in a plan's network is especially important here.
