Abstract
- Issue: The United States has made historic progress on insurance coverage since the Affordable Care Act became law in 2010, with 20 million fewer people uninsured. However, we must also measure progress by assessing how well people who have insurance from all coverage sources are protected from high health care costs.
- Goals: To estimate the number and share of U.S. insured adults who are “underinsured” or have out-of-pocket costs and deductibles that are high relative to their incomes.
- Method: Analysis of the Commonwealth Fund Biennial Health Insurance Surveys, 2003–2016.
- Findings: As of late 2016, 28 percent of U.S. adults ages 19 to 64 who were insured all year were underinsured — or an estimated 41 million people. This is more than double the rate in 2003 when the measure was first introduced in the survey, and is up significantly from 23 percent, or 31 million people, in 2014. Rates climbed across most coverage sources, and, among privately insured, were highest among people with individual market coverage, most of whom have plans through the marketplaces. Half (52%) of underinsured adults reported problems with medical bills or debt and more than two of five (45%) reported not getting needed care because of cost.
Background
The Affordable Care Act (ACA) has transformed the health insurance market, allowing Americans who lack job-based health benefits access to affordable health insurance options. The law’s coverage expansions and protections have reduced the number of uninsured adults by more than 20 million.
Congress intended for the ACA to do more than expand access to insurance; it aimed for the new coverage to allow people to get needed health care at an affordable cost. Accordingly, for marketplace plans, the law includes requirements toward that end: an essential health benefit package, cost-sharing reductions for lower- income families, and out-of-pocket cost limits.1 For those covered by the law’s Medicaid expansion, there is little or no cost-sharing in most states.2
For people covered by employer-based insurance — which includes more than half of Americans under age 65, or more than 150 million people3 — plans were historically far more comprehensive and cost-protective than individual market coverage.4 However, over the past decade, premium cost pressures have led companies to share increasing amounts of health costs with workers, particularly in the form of higher deductibles.5 At the same time, income growth has been sluggish, leaving families increasingly pinched by health care costs.
In this issue brief, we focus on how well health insurance protects people from medical costs, using a measure of “underinsurance” from the Commonwealth Fund’s Biennial Health Insurance Survey to examine trends from 2003 to 2016. Adults in the survey are defined as underinsured if they had health insurance continuously for the preceding 12 months but still had out-of-pocket costs or deductibles that were high relative to their incomes (see Box). The survey was conducted between July 12 and November 20, 2016. We examined underinsured rates across all coverage sources, including private (employer and individual market) and public (Medicaid and Medicare). It is the first time in this survey series that we are able to estimate underinsurance in the ACA’s marketplace plans.
Survey Findings
Estimated 41 Million Adults Are Underinsured
As of July 2016 through November 2016, 28 percent of U.S. adults ages 19 to 64 who were insured all year, or an estimated 41 million people, were underinsured (Exhibit 1, Table 1). This is more than double the rate in 2003 when the measure was first introduced in the survey, and is up significantly from 23 percent, or 31 million people, in 2014.6
Underinsured rates by source of coverage. The underinsured population is predominantly composed of people in employer plans: 56 percent of underinsured adults had coverage through employers at the time of the survey (Table 2).7 This reflects the fact that the majority of insured adults have employer coverage. However, people with coverage through the individual market, including the ACA marketplaces, and Medicare beneficiaries who are disabled adults under age 65, are disproportionately represented among the underinsured.
The share of adults who were underinsured has climbed over time in each coverage group. Among adults with employer-based coverage at the time of the survey, 24 percent were underinsured, which is more than double the rate in 2003, and is up significantly from 2014 (Exhibit 2). People working in small firms historically have had somewhat higher underinsured rates than employees of larger firms. But in 2016, the share of adults in firms with 100 or more workers who were underinsured climbed significantly to 22 percent — the same rate as among workers in small companies.
People with individual market coverage, including those in marketplace plans, are significantly more likely to be underinsured than people in employer plans. In 2016, 44 percent of adults with individual market policies, including marketplaces plans, were underinsured.
One-quarter (26%) of adults with Medicaid coverage — the poorest adults in the survey — were underinsured in 2016. Medicaid requires little cost-sharing, but because people eligible for the program have very low incomes, minor out-of-pocket costs can comprise a large share of income.
Adults under age 65 with Medicare who were continuously insured are by far the sickest group of covered adults in the survey — 77 percent have a chronic condition or are in fair or poor health — and the second-poorest after Medicaid enrollees (data not shown).8 Many have very high health expenditures and low incomes. Almost half (47%) of adults in this group were underinsured in 2016.
Underinsured rates in the four largest states. The survey drew an additional sample of people in the nation’s four most populous states.9 Adults in Florida and Texas were underinsured at higher rates than those in California and New York. Among adults who were insured all year, 32 percent of Floridians and 33 percent of Texans were underinsured compared with 21 percent of Californians and New Yorkers (Exhibit 3, Table 3).
Differences in deductibles were a notable factor in the divide. Larger shares of adults in Florida and Texas had deductibles that were high relative to income compared to those in New York and California (Table 3). According to federal data, deductibles in employer plans are both more prevalent and higher on average in Florida and Texas than in California and New York.10
Higher Deductibles Are Increasingly a Factor in the Underinsured Rate
Between 2003 and 2016, deductibles were increasingly a factor in underinsurance: more people than ever before have plans with deductibles and more have deductibles that are high relative to income.
The share of privately insured adults who had health plans without deductibles has fallen by nearly half over the past 13 years, from 40 percent in 2003 to 22 percent in 2016 (Exhibit 4, Table 4). At the same time, deductibles have grown in size. By 2016, more than one of 10 (13%) adults enrolled in a private plan had a deductible of $3,000 or more, up from just 1 percent in 2003.11
Deductibles are outpacing growth in many families’ incomes, and thus representing a greater share of income.12 In 2016, 12 percent of adults with insurance coverage all year, or 18 million people, had a deductible that comprised 5 percent or more of their income, up from 3 percent, or 4 million people, in 2003 (Exhibit 5, Table 1).
High deductibles by coverage source. Deductibles that are high relative to income are more common in the individual market, but have grown increasingly prevalent in employer plans. Among those insured all year, about one-quarter of adults with individual market policies and marketplace plans had deductibles that equaled 5 percent or more of their income, up from 7 percent in 2003. Among people who had employer coverage, the share with a high deductible grew from 2 percent in 2003 to 13 percent in 2016 (Exhibit 5).
Large deductibles have been most common among small employers, but in 2016 the share of workers in large firms with high deductibles climbed significantly. Among adults with health benefits through their own employer who were working part-time or full-time in companies with 100 or more workers, the share with a high deductible relative to income climbed to 13 percent, the same rate as in small-employer plans.
When we examined the data more closely in the individual market, we found differences by income that likely reflect the effects of the Affordable Care Act’s cost-sharing reductions. These reductions lower deductibles and other cost-sharing elements for lower-income enrollees in marketplace plans. In 2016, a smaller share of adults with incomes under 200 percent of poverty ($23,760 for an individual and $48,600 for a family of four) in the individual market had high deductibles relative to their income than did higher-income enrollees (data not shown). In contrast, in employer plans, lower-income enrollees have higher deductible burdens than do higher-income employees because the deductible amount does not vary with income. We have found a similar pattern in analyses of other survey data since the ACA’s major coverage expansions in 2014.13
Adults with Low Incomes or Health Problems Are at Greatest Risk of Underinsurance
People with low incomes in the United States are by far the most at risk of being underinsured. Among adults who had health insurance for the full year, 44 percent of those with incomes under 200 percent of the federal poverty level ($23,760 for an individual and $48,600 for a family of four) were underinsured in 2016, more than twice the rate of adults with incomes over 200 percent of poverty (20%) (Exhibit 6). Low-income adults comprised 61 percent of the 41 million underinsured adults in 2016 (Table 2).
People with health problems are also at greater risk of being underinsured because of their relatively higher health care costs. Among adults who were insured all year, more than one-third (34%) of those in fair or poor health or those with a chronic health problem were underinsured in 2016, compared to 23 percent of those in better health (Exhibit 6).
Underinsured Adults Have High Rates of Medical Bill Problems
Greater cost exposure is leaving Americans burdened with medical debt. Half (52%) of underinsured adults reported problems paying their medical bills or said they were paying off medical debt (Exhibit 7, Table 5). This is about the same rate as adults who were uninsured for some time during the year and more than twice the rate reported by insured adults who were not underinsured (25%). The two states with the highest share of underinsured adults (Florida and Texas) also had the highest shares of insured adults who reported problems paying their medical bills (Table 3).
Among adults with private coverage who had been insured all year, those with high deductibles were more likely to report problems with medical bills than those with low or no deductibles. Two of five (40%) adults with a deductible of $3,000 or more said they had difficulty paying their medical bills or had accumulated medical debt compared with 21 percent of those who did not have a deductible (Exhibit 8, Table 5).
Among adults who were paying off medical bills over time, those who had high deductibles were carrying the largest debt loads. Nearly two of five (39%) privately insured adults with deductibles of $1,000 or higher were paying off accumulated medical bills of $4,000 or more (Table 5).
Medical Bill and Debt Problems Have Long-Term Financial Consequences
Many adults who have struggled to pay their medical bills report lingering financial problems. People who are either underinsured or uninsured have the highest rates of such problems: both groups had higher debt loads and lower incomes than adequately insured adults (data not shown). Half (47%) of underinsured adults who had problems paying medical bills or had medical debt said they had used up all their savings to pay their bills; 40 percent said they had received a lower credit rating because of their bills (Exhibit 9, Table 5). Over one-third (38%) of underinsured adults with medical bill problems said they had taken on credit card debt to pay bills. About 6 percent of underinsured adults reported they had to declare bankruptcy.
Underinsured Adults Report Not Getting Needed Care Because of Cost
Underinsured adults are more likely to skip needed health care because of cost than are adults with more cost-protective insurance. More than two of five (45%) underinsured adults reported not getting needed care because of cost in the past year, including not going to the doctor when sick, not filling a prescription, skipping a test or treatment recommended by a doctor, or not seeing a specialist (Exhibit 10, Table 6). This is twice the rate of continuously insured adults who were not underinsured (22%). It is also close to the rate reported by adults who were uninsured (52%). The two states with the highest share of underinsured adults (Florida and Texas) also had the highest shares of insured adults who reported cost-related problems getting needed health care (Table 3).
Privately insured adults who had health plans with high deductibles were more likely than those with no deductibles to report cost-related problems getting health care. More than two of five (47%) privately insured adults who were insured all year with a deductible of $3,000 or more reported not getting needed care because of cost compared with 22 percent of adults who did not have a deductible (Exhibit 11, Table 6).
Many underinsured adults with health problems reported difficulty getting appropriate care. Among underinsured adults with at least one chronic health condition, nearly a quarter (24%) said they had not filled a prescription for their condition or had skipped a dose of their medication because of cost, compared with 10 percent of those with adequate coverage. (Exhibit 12, Table 6).14 Similarly, underinsured adults with chronic health conditions were more likely to say they had gone to the emergency room or stayed overnight in the hospital for their condition than were adequately insured adults with health problems.
Conclusion and Policy Implications
Since the passage of the Affordable Care Act in 2010, the nation has experienced gains in coverage, as well as improvements on key indicators of access and medical bill problems.15 These improvements reflect coverage gains — fewer people are exposed to the full cost of health care — as well as more comprehensive health plans with greater cost protection. This is especially true for low-income people covered by Medicaid and marketplace plans. But, as this analysis shows, the United States has not eliminated cost-related barriers to timely health care or protected people from medical debt. While these problems continue to be most apparent in the individual insurance market, they are increasing in the employer group market. Even public insurance programs like Medicare, which covers seniors and disabled people under age 65, leave many struggling to pay for health care.16
The latest Republican-led effort to repeal and replace the Affordable Care Act would have significantly increased the cost of health care for many Americans. After that effort failed in September, the Trump administration took two major actions in October, which could also have the effect of increasing costs. The first was an executive order to federal agencies to write new regulations that would allow the sale of insurance products that skirt the ACA’s consumer protections and cost-sharing standards.17 In the second action, the administration ended the federal payments for the ACA’s cost-sharing reductions.18 At the other end of the political spectrum, Senator Bernie Sanders has introduced legislation that would phase out the ACA and eliminate most cost-sharing in a Medicare-for-All framework. Seeking middle ground, Senators Lamar Alexander and Patty Murray held hearings on stabilizing the marketplaces in September, which included an appropriation for the cost-sharing reductions. To reduce the number of underinsured people in our health system, we also suggest the following policy options:
For people in individual market and marketplace plans
- Increase the cost coverage of health plans. The law’s cost-sharing reductions (CSRs) increase the actuarial value (the percentage of medical costs covered on average by a health plan) of the marketplace’s silver level plans from 70 percent to as high as 94 percent for people with incomes under 250 percent of poverty ($30,150 for an individual and $61,500 for a family of four). The Commonwealth Fund has found that these reductions have been effective in lowering deductibles for those eligible to levels in employer plans.19 To counteract the administration’s executive order, Congress can immediately reinstate the cost-sharing reduction payments by making an appropriation. Since the Congressional Budget Office (CBO) has already assumed the cost of the CSRs in the federal budget baseline, the appropriation is a formality: it would not increase the federal deficit. To make health care more affordable for middle-class families, Congress could then consider extending the CSRs higher up the income distribution.
- Increase the number of services excluded from the deductible. Most plans sold in the individual market nationwide exclude certain services from the deductible, such as primary care visits and certain prescriptions.20 In 2016, the U.S. Department of Health and Human Services (HHS) provided a standardized plan option for insurers that excluded eight services from the deductible at the silver and gold level. These include primary and specialty care visits, urgent care visits, mental health and substance-use disorder outpatient visits, and all prescription drugs. HHS or Congress could make these exceptions mandatory for all plans. Covered California, the California marketplace, requires all health plans sold in the marketplace to exclude all physician visits and outpatient services from the deductible.
- Simplify the metal tiers and increase premium tax credits. As an alternative to extending cost-sharing reductions to people above 250 percent of poverty, Congress could lower the number of metal tiers in the individual market from four to two at higher actuarial values. For example, insurers could be required to sell just gold and platinum plans, which have actuarial values of 87 percent and 94 percent and much lower deductibles and copayments than silver and bronze plans. Tax credits would adjust to reflect the plans’ higher premium costs. This avoids the circuitous route of covering insurers’ costs through the cost-sharing reductions. Premium tax credits could be increased and extended to people earning more than 400 percent of poverty.21
For people in employer plans
- Set a standard actuarial value for employer plans. Currently under the ACA, people in employer plans may become eligible for marketplace tax credits if the actuarial value of their plan is less than 60 percent. Congress could increase this level to 70 percent (the level of silver plans) or higher.
- Set standards for deductible exclusions in employer plans. Most employer plans exclude at least some services from their deductibles.22 Congress could set a minimum set of exclusions that could resemble the current standard plan option for the marketplaces.
Addressing the Key Driver of Insurance Costs: Health Care Cost Growth
Health care costs are the single largest factor in the growth of private insurance premiums in the United States. Insurers and employers have tried to manage premium growth by making consumers increasingly responsible through higher deductibles and other cost-sharing vehicles. Advocates of this approach argue that with more skin in the game, consumers will help to slow cost growth by choosing more-efficient providers and being more selective in the services they use. But years of experience with high-deductible health plans in the U.S. has yielded scant evidence that such a strategy is effective. Instead, as the survey findings indicate, many consumers have responded to higher deductibles by avoiding needed health care and skipping their medications.
Innovations under way in the delivery system, some of which stem from the ACA, have helped slow the rate of growth in health care costs in the past few years. But moving the nation closer to the performance of other countries on both cost and health outcomes will require considerably more work.23 While targeted consumer cost-sharing may help to reduce use of low-value health services, this approach is unlikely to be successful unless consumers are better informed on prices and the value of alternative approaches to their health care problems. Such information is largely unavailable. Evidence suggests that consumers cannot do the heavy lifting required to reduce the rate of growth in medical costs in the United States.
