Supplementary & Private Health Insurance

UnitedHealthcare and Humana were the defining names in health insurance this October, after both announced Medicare Advantage plan exits that affect nearly one million people during open enrollment. The cutbacks forced seniors to rethink their coverage at the very moment they were comparing options for the coming year. Cigna added to the pressure by pulling back from ACA exchanges across several states, a move that made it one of the most closely watched insurers in the marketplace. Centene and Molina Healthcare also reduced their footprints in marketplace and Medicaid programs, signaling that the cost pressures squeezing insurers are reshaping where they are willing to compete. CVS Health's Aetna followed the same path with its ACA exit while keeping a large Medicare presence, and Elevance Health faced questions about possible Medicaid exits and sharp swings in its membership. Kaiser Permanente, meanwhile, drew consumers during the peak plan-shopping season, and Oscar Health continued to be one of the few insurers still building its presence in the ACA market.

The broader picture is one of retreat from some markets and selective expansion in others, with the biggest names pruning plans that no longer pencil out. Patients and families are bearing the practical consequences, facing fewer choices and new decisions as open enrollment deadlines approach. Insurers are shifting their bets toward the regions and programs where they expect to stay profitable. For the category, the question heading into 2027 is how much coverage will remain available in the markets that big carriers are leaving behind.
