Abstract

Health insurance plays a critical role in access to and delivery of health care in the United States. As the only industrialized nation without universal health coverage, Americans without adequate insurance (i.e., uninsured or underinsured individuals) face numerous obstacles to obtaining necessary health care. In this article, we review the mechanisms by which inadequate insurance leads to worse clinical outcomes in patients with common benign and malignant colorectal pathologies. We then discuss several evidence-based solutions for improving access to optimal colorectal care for these patients. These include increasing access to and affordability of health insurance, mitigating disparities between differently insured populations, strengthening the health care safety net, and tailoring outreach and clinical decision-making for the uninsured and underinsured. By exploring the nuance and impact of inadequate insurance coverage, we ultimately seek to highlight critical opportunities for future research and advocacy within the realm of insurance design and policy.
