Medical debt is a real burden for many families, and I don't want to minimize that. But the commonly cited statistic that medical bills are the leading cause of bankruptcy is based on flawed research that has been significantly challenged.

The famous claim comes from a study co-authored by Elizabeth Warren, which counted any bankruptcy where the filer had at least $1,000 in medical debt or listed illness as a contributing factor. By that loose definition, someone who went bankrupt primarily from credit card debt and job loss but also had a medical bill would be counted as a 'medical bankruptcy.'

A more rigorous 2018 study published in the New England Journal of Medicine by economists Carlos Dobkin and others used hospitalization records matched to credit reports and found that medical expenses were directly responsible for only about 4% of bankruptcies among non-elderly adults. The vast majority of bankruptcies involve multiple factors — job loss, divorce, overspending — with medical bills being one piece of a larger financial picture.

It's also worth noting that bankruptcy filings have actually declined significantly since the ACA expanded coverage. Total bankruptcy filings dropped from 1.5 million in 2010 to about 420,000 in 2023. If medical bills were truly the primary driver, you wouldn't see such a dramatic drop while healthcare costs continued rising.

The U.S. also has extensive safety nets for medical costs. Medicaid covers low-income individuals. The ACA provides subsidized insurance for those earning up to 400% of the poverty line. Hospitals are required to provide emergency care regardless of ability to pay under EMTALA. Most hospitals have charity care programs.

None of this means the system is perfect. High deductibles are a real problem. Price transparency is lacking. But the 'medical bankruptcy epidemic' narrative is based on inflated statistics that don't hold up to scrutiny.
