U.S. Health Insurance Coverage in 2020: A Looming Crisis in Affordability

What did health insurance coverage look like for U.S. adults in the first half of 2020 as the country slid into the worst public health and economic crisis in generations? In this brief, we present findings from the Commonwealth Fund’s latest Biennial Health Insurance Survey, which assesses the extent and quality of coverage for U.S. working-age adults. We’ve conducted this survey since 2001. It uses three measures to gauge the adequacy of insurance coverage:

• whether or not people have insurance
• if they have insurance, whether they experienced a gap in coverage in the prior year
• whether high out-of-pocket costs and deductibles are causing them to be underinsured, despite having continuous coverage throughout the year.

The survey began on January 14, 2020 — just before the outbreak of the coronavirus pandemic in the United States. We interviewed a nationally representative sample of 4,272 adults ages 19 to 64 about their health insurance coverage through June 5. (See “How We Conducted This Study” for more detail.) Despite the severity of the pandemic and the abrupt disruption in economic activity beginning in March, the survey did not find statistically significant changes in coverage from the last time it was conducted in 2018. But it does show a persistent vulnerability among working-age adults in their ability to afford coverage and health care that could worsen if the economic downturn continues.

Survey Highlights

• In the first half of 2020, 43.4 percent of U.S. adults ages 19 to 64 were inadequately insured. This is statistically unchanged from the last time we fielded the survey in 2018.
• The adult uninsured rate was 12.5 percent. In addition, 9.5 percent of adults were insured but had a gap in coverage in the past year and 21.3 percent were underinsured. These findings are also statistically unchanged from 2018.
• There was no statistically significant change in coverage inadequacy between the months leading up to the pandemic and the months that followed, but this may change as the pandemic continues.
• Half of adults who spent any time uninsured or who were underinsured reported problems paying medical bills or said they were paying off medical debt over time. A quarter of those who were continuously insured and did not meet the threshold for underinsurance also reported problems paying bills.
• People who reported problems paying medical bills experienced lingering financial problems including damage to their credit ratings and depleted savings.

In the first half of 2020, 43.4 percent of adults were inadequately insured. This group is made up of people who were uninsured at the time of the survey (12.5%), were insured but had experienced a coverage gap in the past year (9.5%), or were insured continuously but had such high out-of-pocket costs or deductibles relative to their income that they were effectively underinsured (21.3%).¹ (See box above.)

Despite the pandemic, we find no statistically significant change in any of our measures of coverage adequacy from 2018. We also did not find significant changes in coverage adequacy between the months leading up to the pandemic and the months that followed, but this may change as the pandemic continues.

The uninsured rate we found falls into the range of estimates of recent federal surveys conducted in 2018 and 2019 (11.7% and 13.7%, respectively.) (See “Estimates of U.S Uninsured Rates” for detail.) It is important to note that our estimated uninsured rate has a margin of sampling error of +/– 1.3 percent and therefore, the true estimate is likely between 11.2 percent and 13.9 percent.²

More than one-third of Latino adults, workers in small businesses (i.e., fewer than 20 employees), and adults with low incomes were either uninsured at the time of the survey or spent some time uninsured in the past year (Table 1). This was two or more times higher than comparison groups. Young adults also reported high rates of being uninsured. People with incomes below 133 percent of the federal poverty level (i.e., $16,971 for an individual and $34,846 for a family of four in 2020) reported uninsured rates that were three times higher than adults with incomes at 400 percent of the poverty level or higher (i.e., $51,040 for an individual and $104,800 for a family of four). They also had underinsured rates that were two times as high as their higher-income counterparts.

Among people who were insured all year in private health plans, people who were enrolled in plans they bought on their own in the individual market — either directly from an insurer or the Affordable Care Act (ACA) marketplaces — were underinsured at the highest rates. But one-quarter of adults in employer plans also were underinsured. Because there were an estimated 122 million working-age people in employer plans, compared to just 15 million in the individual market, there were far more underinsured people with employer coverage than with individual market insurance.³ The growth in the underinsured since 2010 has been driven by increasingly inadequate coverage in employer health plans.

The Commonwealth Fund’s measure of underinsurance includes how much people spent out of pocket in the past year and the size of their deductible, both calculated as a share of their income. Over the past decade, deductibles have grown both in prevalence and size. The share of the adult population in private health plans with deductibles of $1,000 or more doubled between 2010 and 2020.

In 2010, only 7 percent of people in private plans had deductibles that amounted to 5 percent or more of income. By 2016, that share was 15 percent. Because of the dominance of employer coverage in U.S. health insurance, this overall rate has closely tracked that of people enrolled in employer plans.

People who get coverage in the individual market and ACA marketplaces face higher deductibles, on average, relative to their incomes, than people in employer plans. Those with incomes under 250 percent of poverty ($31,900 for an individual and $65,500 for a family of four in 2020) are eligible for marketplace plans with reduced cost-sharing, including lower deductibles. But people with incomes over that threshold see higher deductibles, which ranged as high as $8,150 for silver-level plans in the 38 states where the federal government operated the marketplaces in the 2020 plan year.⁴

Inadequate insurance coverage leaves people exposed to high health care costs; these expenses can quickly turn into medical debt. Half of adults who spent any time uninsured and those who were underinsured reported problems paying medical bills or said they were paying off medical debt over time. But rates also were high among people with coverage all year who were not underinsured: one-quarter reported medical bill problems or debt. Even though their income combined with their insurance deductible and out-of-pocket spending didn’t meet the threshold for underinsurance, they still struggled with medical bills. The majority of people in this group had employer coverage (data not shown).

The majority (67%) of adults who reported medical bill or debt problems said the person in their household who incurred the medical bill was insured when the care was provided (Table 5). Among those paying off debt over time, more than half (54%) had incurred debt of $2,000 or more.

Among demographic groups, Blacks were significantly more likely than whites to report problems with medical bills (45% vs. 35%), as were lower-income people (133% of poverty or lower) compared to people with higher incomes (400% of poverty or higher) (42% vs. 27%) (data not shown).

Paying off accumulated medical debt over time can have a major impact on people’s lives. Many adults with medical bill or debt problems reported serious financial problems. Among those who reported any medical bill or debt problem, 37 percent said they had used up all their savings to pay their bills, 40 percent had received a lower credit rating as a result of their medical debt, 31 percent racked up debt on their credit cards, and one-quarter were unable to pay for basic necessities such as food, heat, or rent. People who were underinsured were particularly affected: nearly half (48%) said they had used up all their savings to pay off their bills (Table 5).

While insurance status is not the only determinant of whether a person has access to health care, it is the most important.⁵ Research has concluded that the ACA’s coverage expansions led to significant improvements in access over the past 10 years.⁶ But financial barriers to care remain in the U.S. because millions of people either lack insurance or have coverage with significant cost-sharing. More than one-third (35%) of all adults reported at least one cost-related problem getting needed health care in the past year including not filling a prescription; skipping a recommended test, treatment or follow-up visit; not going to a doctor when sick; or not getting needed specialist care. Rates were highest among adults who spent any time uninsured during the year (56%) and those who were underinsured (43%). But even adults who were insured all year and not underinsured had access issues: 23 percent reported at least one cost-related problem getting health care. Most of this group had employer coverage (data not shown).

Cost-related problems getting needed care were higher among people with incomes below 133 percent of poverty compared to those with incomes of 400 percent of poverty or more (42% vs. 25%), and also among workers in small businesses of less than 20 employees compared to those in companies with 100 or more employees (42% vs. 31%) (data not shown).

The survey indicates that deductibles alone are associated with financial problems and may impact people’s decisions about whether to get needed health care. People in private health plans who were insured all year with deductibles of $1,000 or more were significantly more likely than those with lower or no deductibles to report problems paying medical bills or said they were paying off medical debt over time. Of this group, only half (53%) met the definition of underinsured (data not shown). People with higher deductibles also were carrying higher debt loads: 62 percent of people with deductibles of $1,000 or more who said they were paying off medical debt had incurred debt of $2,000 or more compared to 46 percent of those with lower deductibles who owed payments for bills (Table 5).

Higher deductibles can lead people to decide against getting needed care even if they have health problems. People with at least one health problem who were enrolled in higher-deductible plans were more likely to report that they had not filled a prescription or had skipped a dose of medication for their health problem than people with lower or no deductibles.
