When Melanie Miller saw that her health insurance premium payment was set to nearly triple to $914 a month this year, she stopped shopping on the Affordable Care Act marketplace.The 59-year-old retired teacher, who recently moved from Ohio to Michigan, now pays $341 a month for a pair of plans, one that covers routine and urgent care and another that pays fixed amounts for hospital stays. Neither meets federal standards for comprehensive coverage.Though she practices yoga and is healthy, Miller said she still feels "vulnerable." If she lands in the hospital, her plan pays a flat $2,000, a fraction of the $30,000 price tag of an average hospital stay."I don't gamble. But I may as well," she said. "This is gambling."Congress' decision late last year not to extend enhanced marketplace tax credits has boosted the appeal of alternatives to comprehensive insurance — plans like Miller's, which have lower premiums but don't meet ACA standards for coverage or consumer protections. Unlike plans sold on the exchanges, these options — some sold by major insurers, others by small companies or nonprofits — can deny claims with few or no legal rights for consumers to appeal. The plans are not required to cover "essential health benefits," such as preventive care, and can impose annual or lifetime caps on benefits.There is debate over whether these options help or harm patients. Consumer advocates dismiss them as "junk insurance," while proponents say restricting alternatives to pricey marketplace plans risks driving up the number of uninsured. Some states, including Kansas and Florida, and the federal government itself have eased regulations on such plans or created incentives to join them, while other states, including California and Massachusetts, have tried to deter enrollment in alternative insurance. Those regulatory guardrails, however, are now being stress-tested as premiums blow out household budgets.Alternative insurance takes many forms, including short-term policies, which were designed to bridge temporary gaps in coverage and often exclude preexisting conditions, and fixed-indemnity plans, which pay a flat rate per service regardless of how high costs go and are intended for supplemental use. Arrangements in which people pool their money to cover one another's bills, including faith-based "healthcare sharing ministries," also provide a cheaper alternative to the marketplace options. Because they are not considered insurance under federal or state law, they are not legally bound to pay for even eligible medical bills.
