A recent report on health insurance coverage in the United States for the year 2021 has shed light on an intriguing phenomenon - over 43 million Americans held more than one type of health insurance coverage. While the majority of the population relies on private health insurance, either through employers or government programs, a significant number of individuals found themselves with multiple plans. This was especially true for older adults, who often supplemented Medicare with privately purchased plans or employer coverage. Additionally, low-income families had a higher likelihood of having multiple coverage options, thanks to qualifying for both public and private health insurance options.
The report revealed that adults aged 65 and older were the age group most likely to have multiple health insurance plans. For many elderly individuals, Medicare coverage was supplemented with private insurance acquired either directly or through their current or previous employers. This phenomenon affected more than half (51.9%) of adults in this age group, accounting for approximately 29.2 million people with multiple coverage. In contrast, the younger age groups of 19 to 64 years old and individuals under 19 had significantly lower rates of holding more than one type of health coverage, at 5.5% and 4.1%, respectively.
Income played a significant role in determining the likelihood of having multiple health insurance plans. Families below certain income-to-poverty thresholds qualified for public health insurance options, contributing to the increase in multiple coverage holders. In 2021, approximately 13.7% of individuals with incomes between 100% and 399% of their poverty threshold had more than one type of health coverage. This figure was followed by 12.9% of those with incomes at or above 400% of the federal poverty level and 12.1% of those living in poverty.
In 2021, working-age adults between 15 and 64 years old with a disability were significantly more likely (17.1%) to have multiple health insurance coverage compared to those without a disability (4.3%). People with disabilities often qualified for dual coverage through Medicaid and Medicare, which helped explain this disparity. This additional coverage provided necessary support and assistance to individuals with disabilities in managing their healthcare needs.
The majority of individuals (75.5%) with multiple coverage in 2021 had both private and public insurance. Around 25.7 million people (59.6% of those with multiple coverage) held both Medicare and some form of private insurance, reflecting the higher percentage of multiple coverage holders aged 65 and older. Additionally, 6.8 million individuals (15.7%) had both Medicaid and private coverage, while another 15.7% were covered by both Medicaid and Medicare.
The report's findings offer valuable insights into the complexity and diversity of health insurance coverage in the United States. With over 43 million Americans holding multiple health insurance plans, it is clear that individuals seek to customize their coverage to meet specific needs. While older adults and low-income individuals showed a higher likelihood of having multiple coverage, the reasons behind this trend warrant further investigation. Policymakers and healthcare providers can utilize this data to better understand the needs of different populations and design targeted strategies to ensure access to comprehensive and affordable healthcare for all.
