The Affordable Care Act (ACA) made historic strides in expanding access to health insurance coverage by covering an additional 20 million Americans. President Joe Biden ran on a platform of building upon the ACA and filling in its gaps. With Democratic majority in the Senate, aspects of his health care plan could move from idea into reality.
The administration’s main focus is on uninsurance, which President Biden proposes to tackle in three main ways: providing an accessible and affordable public option, increasing tax credits to help lower monthly premiums, and indexing marketplace tax credits to gold rather than silver plans.
However, underinsurance remains a problem. Besides the nearly 29 million remaining uninsured Americans, over 40% of working age adults are underinsured, meaning their out-of-pocket cost-sharing, excluding premiums, are 5-10% of household income or more, depending on income level.
High cost-sharing obligations—especially high deductibles—means insurance might provide little financial protection against medical costs beneath the deductible. Bills for several thousand dollars could financially devastate a family, with the insurer owing nothing at all. Recent trends in health insurance enrollment suggest that uninsurance should not be the only issue to address.
A high demand for low premiums
Enrollment in high deductible health plans (HDHP) has been on a meteoric rise over the past 15 years, from approximately 4% of people with employer-sponsored insurance in 2006 to nearly 30% in 2019, leading to growing concern about underinsurance. “Qualified” HDHPs, which come with additional tax benefits, generally have lower monthly premiums, but high minimum deductibles. As of 2020, the Internal Revenue Service defines HDHPs as plans with minimum deductibles of at least $1,400 for an individual ($2,800 for families), although average annual deductibles are $2,583 for an individual ($5,335 for families).
HDHPs are associated with delays in both unnecessary and necessary care, including cancer screenings and treatment, or skipped prescription fills. There is evidence that Black patients disproportionately experience these effects, which may further widen racial health inequities.
A common prescription has been to expand access to Health Savings Accounts (HSAs), with employer and individual contributions offsetting higher upfront cost-sharing. Employers often contribute on behalf of their employees to HSAs, but for individuals in lower wage jobs without such benefits or without extra income to contribute themselves, the account itself may sit empty, rendering it useless.
A recent article in Health Affairs found that HDHP enrollment increased from 2007 to 2018 across all racial, ethnic, and income groups, but also revealed that low-income, Black, and Hispanic enrollees were significantly less likely to have an HSA, with disparities growing over time. For instance, by 2018, they found that among HDHP enrollees under 200% of the federal poverty level (FPL), only 21% had an HSA, while 52% of those over 400% FPL had an HSA. In short, the people who could most likely benefit from an HSA were also least likely to have one.
If trends in HDHP enrollment and HSA access continue, it could result in even more Americans who are covered on paper, yet potentially unable to afford care.
Addressing uninsurance could also begin to address underinsurance
President Biden’s health care proposal primarily addresses uninsurance by making it more affordable and accessible. This can also tangentially tackle underinsurance.
To make individual market insurance more affordable, Biden proposes expanding the tax credits established under the ACA. His plan calls for removing the 400% FPL cap on financial assistance in the marketplaces and lowering the limit on health insurance premiums to 8.5% of income. Americans would now be able to opt out of their employer plan if there is a better deal on HealthCare.gov or their state Marketplace. Previously, most individuals who had an offer of employer coverage were ineligible for premium subsidies—important for individuals whose only option might have been an employer-sponsored HDHP.
Biden also proposes to index the tax credits that subsidize premiums to gold plans, rather than silver plans as currently done. This would increase the size of these tax credits, making it easier for Americans to afford more generous plans with lower deductibles and out-of-pocket costs, substantially reducing underinsurance.
The most ambitious of Biden’s proposed health policies is a public option, which would create a Medicare-esque offering on marketplaces, available to anyone. As conceived in Biden’s proposal, such a plan would eliminate premiums and having minimal-to-no cost-sharing for low-income enrollees; especially meaningful for under- and uninsured people in states yet to expand Medicaid.
Moving forward: A need to directly address underinsurance
More extensive efforts are necessary to meaningfully address underinsurance and related inequities. For instance, the majority of persons with HDHPs receive coverage through an employer, where the employer shares in paying premiums, yet cost-sharing does not adjust with income as it can in the marketplace. Possible solutions range from employer incentives to expanding the scope of deductible-exempt services, which could also address some of the underlying disparities that affect access to and use of health care.
The burden of high cost-sharing often falls on those who cannot afford it, while benefitting employers, healthy employees, or those who can afford large deductibles. Instead of encouraging HSAs, offering greater pre-tax incentives that encourage employers to reabsorb some of the costs that they have shifted on their lower-income employees could prevent the income inequity gap from widening further.
Under the ACA, most health insurance plans are required to cover certain preventative services without patient cost-sharing. Many health plans also exempt other types of services from the deductible – from generic drugs to certain types of specialist visits – although these exemptions vary widely across plans. Expanding deductible-exempt services to include follow-up care or other high-value services could improve access to important services or even medication adherence without high patient cost burden. Better educating employees about what services are exempt would make sure that patients aren’t forgoing care that should be fully covered.
Health insurance is complicated. Choosing a plan is only the start. More affordable choices are helpful only if these choices are fully understood, e.g., the tradeoff between an HDHP’s lower monthly premium and the large upfront out-of-pocket cost when using care. Investing in well-trained, diverse navigators to help people understand how their options work with their budget and health care needs can make a big difference, given that low health insurance literacy is related to higher avoidance of care.
The ACA helped expand coverage, but now it’s time to make sure the coverage provided is more than an unused insurance card. The Biden administration has the opportunity and responsibility to make progress not only on reducing the uninsured rate, but also in reducing disparities in access and patient affordability.
