Uninsured in Colorado

Colorado

Health insurance is critical in helping people get the preventive and acute medical care they need to achieve and maintain good health. The nation’s uninsured rate dropped significantly after the Affordable Care Act was enacted, yet over 26.3 million people were still uninsured in 2022. In 2021, an analysis found that 69.6% of uninsured adults reported that they were uninsured because they could not afford health insurance. 

Compared with insured adults, uninsured adults have more health disadvantages, including: 

• Worse health outcomes.
• Higher rates of mortality and premature death.
• Higher rates of cancer mortality and greater risk of late-stage cancer diagnosis. 
• Inadequate access to quality care, including preventive services. 
• Expensive medical bills due to undiagnosed or untreated chronic conditions.
• More complex and expensive emergency room visits. 

Individuals who are uninsured or experience inconsistent health care coverage encounter more interruptions in accessing care and difficulties in covering medical expenses compared to individuals with continuous insurance coverage. 

One study estimated that adults ages 20-64 in three Medicaid expansion states experienced a 6% decline in all-cause mortality compared with adults living in demographically and economically similar states that did not expand Medicaid. This decline was largely from medical conditions that respond well to medical management, such as HIV, heart disease and diabetes.

According to America’s Health Rankings data, the uninsured rate is higher among: 

• Adults ages 26-34 compared with all other age groups. Adults ages 55-64 have the lowest rate. 
• American Indian/Alaska Native and Hispanic adults as well as those who identify as other race compared with other racial and ethnic groups. White adults have the lowest rate.
• Adults with less than a high school education compared with those with higher levels of education.
• Individuals living in non-Medicaid expansion states compared with those in Medicaid expansion states.
• Individuals with income levels below 100% of the federal poverty level compared with individuals with higher incomes. 
• Noncitizen (lawfully present and undocumented immigrants) adults compared with the general U.S. population.

Medicaid expansion has decreased uninsured rates among low-income individuals and vulnerable populations in states that have enacted it. In 2019, 45% of the uninsured population did not have access to health coverage provided by the Affordable Care Act because they lived in a state that had not expanded Medicaid, they were not U.S. citizens or their income was too high to be eligible. Increasing Medicaid expansion could further reduce the number of uninsured individuals. Increasing knowledge of government assistance programs may increase enrollment of eligible individuals. Policy changes can also help address issues with affordability.

Increasing the number of people with health insurance is important to improve health outcomes and decrease health care spending. However, a combination of three core strategies — expanding health insurance coverage, delivering better preventive and chronic care and focusing on community prevention — is more effective at saving lives and money than implementing any of these strategies alone.

A Healthy People 2030 leading health indicator is to increase the proportion of people with health insurance.
