Who are the underinsured?

Area of Science:

• Health Economics
• Public Health Policy
• Social Determinants of Health

Background:

• Inadequate health insurance coverage presents a significant risk for individuals and society.
• Defining and identifying the underinsured population is crucial for policy development.
• Existing insurance structures may not fully protect against substantial medical expenses.

Purpose of the Study:

• To define and empirically identify the population lacking adequate health insurance.
• To analyze the distribution of financial burdens associated with inadequate insurance.
• To inform policy interventions aimed at expanding insurance protection.

Main Methods:

• Utilized data from the National Medical Care Expenditure Survey (NMCES).
• Applied various conceptualizations of financial risk and medical expense.
• Analyzed the nonelderly population's insurance status and exposure to large medical bills.

Main Results:

• Over 25% of the nonelderly population lacks adequate protection against large medical bills.
• The financial hardships faced by the underinsured are broadly distributed.
• Inadequate insurance poses a substantial private burden across diverse demographic groups.

Conclusions:

• A significant portion of the nonelderly population is underinsured.
• The financial consequences of inadequate insurance are widespread and affect many individuals.
• Policy interventions are needed to address the public and private burdens of the underinsured.
