Health Insurance: Who's Covered?

In the United States, the majority of people have some form of health insurance. As of January 2022, 91.6% of Americans had health insurance, according to a report by the US Census Bureau. This is a significant increase from 2010 when the Affordable Care Act was first introduced, with the percentage of insured Americans rising from 83.3%. However, this still leaves a small proportion of the population uninsured, with around 8.4% of Americans lacking health insurance as of 2022. This equates to approximately 27.2 million people, which is a decrease from 2010 when 49.9 million people were uninsured. The reasons for this decrease are multifaceted, but the Affordable Care Act has played a significant role in expanding access to health insurance.

The impact of the Affordable Care Act on insurance coverage

The Affordable Care Act (ACA) was introduced to expand health insurance coverage and improve access to care in the United States. The ACA enabled people to gain coverage by expanding the publicly funded Medicaid program, establishing the Health Insurance Marketplace, and enforcing an individual mandate.

The ACA's impact on insurance coverage has been significant, with millions of previously uninsured individuals gaining coverage. The expansion of Medicaid has been particularly effective, with an estimated 20 million uninsured adults gaining coverage. This has resulted in a decrease in the number of uninsured individuals, with the rate of uninsured nonelderly adults declining nationally.

The ACA has also improved access to care, particularly for low-income populations. It has been associated with increased health care access, affordability, and use of preventive and outpatient services. The law has made it easier for individuals to obtain care, improved affordability, and reduced delays or foregone care due to costs.

However, there are still challenges and disparities. The reliance of the ACA on health insurance exchanges may pose unintended barriers to access, especially for low-income populations, through the creation of narrow networks and high-deductible plans. Additionally, not all states have expanded Medicaid, resulting in a "coverage gap" where poor, uninsured adults are not eligible for Medicaid or Marketplace subsidies.

Overall, the ACA has had a positive impact on insurance coverage and access to care, but continued monitoring and further policies are needed to address remaining gaps and ensure that the benefits of the law are fully realized.

The number of uninsured people in the US

In 2022, 92.1% of people in the US, or 304 million, had health insurance at some point during the year. This represents an increase in the insured rate and number of insured from 2021 (91.7% or 300.9 million). Private health insurance coverage was more prevalent than public coverage, at 65.6% and 36.1% respectively. The most common type of insurance coverage was employment-based, covering 54.5% of the population for some or all of the calendar year, followed by Medicaid (18.8%), Medicare (18.7%), direct-purchase coverage (9.9%), TRICARE (2.4%), and VA and CHAMPVA coverage (1%).

Despite the overall high rate of insurance coverage in the US, there are still a significant number of people who are uninsured. In 2022, 25.6 million non-elderly individuals were uninsured, a decrease of 3.3 million from 2019. The uninsured rate among working-age adults aged 19-64 decreased by 0.8 percentage points to 10.8% between 2021 and 2022. This decrease was driven in part by a decline in uninsured rates for workers. However, it is important to note that non-elderly adults are more likely to be uninsured than children, with an uninsured rate of 11.3% for adults compared to 5.1% for children in 2022.

The number of uninsured individuals in the US has been on a downward trend since the Affordable Care Act (ACA) was enacted. The ACA included expansions of coverage such as Medicaid expansion and subsidized Marketplace coverage, which served as a safety net for people who lost their jobs or faced other economic disruptions during the coronavirus pandemic. In addition, pandemic-era policies such as continuous enrollment for Medicaid enrollees and enhanced Marketplace subsidies further protected people with low incomes and improved the affordability of private coverage. As a result, the number of non-elderly uninsured individuals decreased by nearly 1.9 million from 2021 to 2022, and the uninsured rate decreased from 10.2% in 2021 to a record low of 9.6% in 2022.

Despite these gains, racial and ethnic disparities in coverage persist. In 2022, more than one in four Hispanic adults ages 18-64 (27.6%) lacked health insurance, a greater percentage than Black, non-Hispanic adults (13.3%), White, non-Hispanic adults (7.4%), and Asian, non-Hispanic adults (7.1%). Adults in non-Medicaid expansion states were also more likely to be uninsured, with an uninsured rate of 19.2% compared to 9.1% in Medicaid expansion states.

The reasons why some people are uninsured

• Cost of insurance: The most common reason for being uninsured is the high cost of insurance. Many people find that the premiums, deductibles, and other out-of-pocket expenses associated with health insurance are simply unaffordable, especially for those with low or moderate incomes.
• Ineligibility for coverage: Some people are uninsured because they are not eligible for coverage. This may include undocumented immigrants, who are often ineligible for federally funded coverage, or those who do not meet the income requirements for certain programs.
• Lack of awareness or understanding: Some people may not be aware that they are eligible for subsidized coverage or may find the process of enrolling in insurance too confusing or complicated. This is especially true for recent immigrants, who may not be familiar with the health insurance system in their new country.
• Employment status: Those who are self-employed or work for small businesses are less likely to have access to employer-provided health insurance and may struggle to afford individual coverage. Additionally, part-time workers or those in contingent or peripheral jobs are less likely to be offered health benefits by their employers.
• Demographic factors: Certain demographic groups are more likely to be uninsured, including young adults, racial and ethnic minorities, non-citizens, and those with lower levels of education. These disparities are often influenced by social and economic factors, such as income and employment opportunities.
• Geographic location: The likelihood of being uninsured also varies by geographic region, with residents of the South and West regions of the United States being more likely to be uninsured than those in other areas. This may be due to differences in state policies, economic conditions, and the availability of employer-sponsored coverage.
• Personal beliefs and preferences: Some individuals may choose to remain uninsured because they do not believe they need or want health insurance, especially if they are young and healthy. Others may view the available insurance options as not worth the cost, especially if the plans have high deductibles or other forms of cost-sharing.

The impact of insurance status on healthcare access

Insurance status has a significant impact on healthcare access. People without health insurance are less likely to seek medical care when necessary and often postpone or forgo it due to the high costs involved. This can have severe consequences, especially when preventable or chronic diseases are left undetected and untreated.

In comparison, individuals with health insurance are more likely to receive preventive services and have a regular source of healthcare. They are also more likely to receive recommended screening tests such as blood pressure checks, cholesterol checks, blood sugar screening, pap smears, mammograms (for women), and colon cancer screening.

The consequences of lacking insurance are not limited to healthcare access. Uninsured individuals often face unaffordable medical bills, which can quickly lead to medical debt, especially for those with low or moderate incomes. They are also more likely to lack confidence in their ability to afford medical costs and may face negative consequences such as using up savings or borrowing money to pay off health-related debts.

Gaining health insurance improves access to healthcare and mitigates the adverse effects of being uninsured. Research shows that individuals who obtain health insurance are more likely to have outpatient visits, receive prescriptions, and experience improved mental health. Furthermore, expansions in health insurance coverage, such as through the Affordable Care Act (ACA), have led to significant improvements in access to care and utilization of health services.

The financial implications of being uninsured

Uninsured people are often charged more for healthcare services than insured people. Hospitals frequently charge uninsured patients two to four times what health insurers and public programs pay for the same services. This means that uninsured people are paying a greater proportion of their income on healthcare, even though their overall medical spending is lower than that of insured people. This disparity is further exacerbated by the fact that uninsured people often have to pay for their medical bills upfront, as they do not have insurance to cover the costs. As a result, they may be forced to negotiate payment schedules, pay with high-interest credit cards, or be turned away altogether.

The lack of insurance can also lead to a delay in seeking medical care, as uninsured people may postpone or forgo care due to the high costs. This can result in poorer health outcomes and an increased risk of premature death. Furthermore, being uninsured can have economic consequences not only for individuals but also for businesses and society as a whole. Employees who are uninsured may miss work or retire early due to health reasons, impacting businesses. Additionally, society may forgo the economic benefits of a healthy and productive population.

Overall, the financial implications of being uninsured can be significant and far-reaching, affecting not only individuals but also businesses and society at large. The high costs of healthcare and the lack of insurance coverage can lead to medical debt, reduced productivity, and poorer health outcomes for those who are uninsured.
