Final answer:
Being underinsured refers to spending a significant part of one's income on healthcare not covered by insurance. The insurance market faces challenges such as adverse selection and regulatory constraints, which can affect the availability and affordability of coverage. Around 51 million Americans lack health insurance due to various reasons, including inadequate employer coverage and ineligibility for Medicaid.
Step-by-step explanation:
When discussing the coverage provided by insurance, it's crucial to understand the concept of being 'underinsured'. Being underinsured means that individuals may be spending a substantial portion of their income on healthcare costs that are not covered by their insurance. For example, according to Schoen, Doty, Robertson, and Collins (2011), people are considered underinsured if they spend at least 10% of their income on healthcare expenses not covered by insurance, or at least 5% in the case of low-income adults. Problems of underinsurance can be compounded by issues such as adverse selection, where individuals with more knowledge about their health risks purchase insurance, potentially leading to higher premiums for others. Furthermore, around 51 million Americans have lacked health insurance, often due to employment situations that do not provide it or due to not qualifying for Medicaid, despite many being under the poverty line.
Regulatory challenges further complicate the landscape of insurance coverage. Insurance companies can't sustainably offer high levels of coverage at low prices without the risk of financial loss. When premiums are set below the level that is actuarially fair for a risk group, others, such as taxpayers or other insurance buyers, may have to compensate for this shortfall. This highlights a fundamental problem in the insurance market: if high-risk individuals are not accounted for correctly, insurers may opt to exit the market, or as an alternative, low-risk individuals might be compelled to purchase insurance at a higher rate than would be fair for their group, raising issues about the government's role and regulations in the industry.
