A recent analysis from the Commonwealth Fund finds that roughly a third of US adults with private health insurance carry unpaid debt to a healthcare provider. This suggests that medical debt is a widespread problem even among people who are not uninsured and who have not necessarily faced a major medical emergency.

The report indicates that the financial protection offered by private insurance is often incomplete, leaving policyholders with out-of-pocket costs they cannot fully pay. While the source does not compare this group to uninsured patients, it underscores that insurance coverage alone does not eliminate the risk of falling into medical debt.

For employers and policymakers, the findings point to a need to examine cost-sharing structures and coverage gaps. The study's authors argue that the prevalence of debt among the privately insured reflects broader affordability issues within the US healthcare system.
