Half of Hospital Bills Go Unpaid: Who’s Paying the Price?

The cost of healthcare continues to soar, placing an ever-growing financial burden on patients and healthcare providers alike. Unpaid medical bills are becoming more common as patient out-of-pocket costs climb, and hospitals are increasingly going unpaid for the services they provide. For hospitals and health systems, uncollected bills pose significant financial challenges, while patients are often forced to make difficult decisions about their care due to affordability concerns. This results in a broken healthcare system in need of a solution that allows hospitals to be paid for their services, while not placing an undue burden on patients who just need care.

Key Takeaways

• More than half of hospital bills go unpaid in full, driven largely by rising patient out-of-pocket costs and high-deductible health plans.
• 51% of private industry workers were enrolled in a high-deductible health plan in 2023 (U.S. Bureau of Labor Statistics).
• Insured patients’ balances now account for a growing share of hospital bad debt: self-pay-after-insurance write-offs rose from 11.1% to 57.6% of hospital bad debt between 2018 and 2021 (Crowe).
• Understanding patients’ out-of-pocket costs and giving them a clear estimate and a manageable way to pay are central to reducing unpaid medical bills.
• Patient financing is one way hospitals can offer affordability without absorbing more bad debt.

Patient Financial Responsibility Quick Facts

• The rise of HDHPs: 51% of private industry workers were enrolled in a high-deductible health plan in 2023, up from previous years, which increases patients’ out-of-pocket exposure and the likelihood of unpaid bills (BLS).

• Uncompensated care costs: Since 2000, hospitals of all types have provided almost $745 billion in cumulative uncompensated care, according to the American Hospital Association (figure reflects data through 2020; more recent totals are higher).

• The out-of-pocket challenge: Insured patients’ ability to pay their balance in full has been dropping, from 76% in 2020 to 54.8% in 2021, as deductibles and out-of-pocket costs rise (Crowe).

• Transparency matters: Billing clarity is a top priority for patients. Providers with clear, upfront pricing and an accurate patient out-of-pocket estimate are more likely to collect payments and retain patient trust.

The Growing Medical Debt Crisis  

Recent studies highlight a troubling reality: hospitals collect only a fraction of what they bill patients. Worse still, the problem is compounding. According to industry data, more than half of hospital bills are never paid in full. This shortfall is largely driven by the rise of high-deductible health plans (HDHPs), which may be more affordable, but shift more financial responsibility onto patients. Many patients are uninformed in their choices, thus unprepared for these out-of-pocket expenses, leading to an increased burden of medical debt.  

Compounding the issue are outdated billing practices that confuse patients and delay payments. To fix this problem, transparent and patient-centered billing processes have become critical for healthcare providers to maintain financial stability. At the same time, patients must contend with the growing need to budget and save for even routine healthcare expenses – an overwhelming and even impossible task for many, especially in the face of rising inflation and economic uncertainty. 

Understanding Patient Out-of-Pocket Costs

Patient out-of-pocket costs are the portion of a medical bill a patient owes directly, including deductibles, coinsurance, and copays, after insurance has paid its share. As HDHPs have become more common, these costs have grown into one of the biggest drivers of both patient financial stress and hospital bad debt.

A clear patient out-of-pocket estimate, given before or at the time of service, helps patients plan for what they’ll owe instead of being surprised by a bill weeks later. For hospitals, giving patients this clarity, paired with a manageable way to pay their share, is one of the most effective ways to reduce the share of patient responsibility cost that ends up as bad debt.

Medical Bills Hit Hard, Insurance or Not 

Insurance is no longer the safety net it once was. According to KFF’s May 2025 Health Tracking Poll, 38% of insured adults under 65 worry about affording their monthly health insurance premium. Separately, about half of U.S. adults say they wouldn’t be able to cover an unexpected $500 medical bill out of pocket without going into debt (KFF).

For those enrolled in HDHPs, the financial strain is exacerbated. A 2024 study found that the percentage of workers with deductibles over $2,000 has nearly doubled in the last 10 years, leaving many families to drain their savings and take out loans to cover unexpected surgeries. This problem extends to hospitals’ bottom line as well: self-pay-after-insurance balances, meaning what insured patients owe out of pocket, made up 57.6% of hospital bad debt in 2021, up from just 11.1% in 2018 (Crowe).

These are not isolated incidents. Medical debt remains a leading cause of bankruptcy in the United States, underscoring the profound toll of rising healthcare costs on everyday Americans (Commonwealth Fund).

Changing Regulatory Environment and Patient Financial Responsibility 

While the Affordable Care Act (ACA) improved access to insurance, its limitations are increasingly evident. Discussions about healthcare reform dominated the political landscape throughout 2024. Critics argued that rising premiums, deductibles, and out-of-pocket maximums are eroding the ACA’s promise of affordability. Proposals for Medicare for All and state-level reforms are gaining traction as policymakers and voters alike search for solutions to make healthcare costs more manageable. 

For healthcare providers, the shifting regulatory environment adds another layer of complexity. New compliance requirements around billing transparency and debt collection practices are reshaping how hospitals approach patient financial responsibility, and providers must adapt quickly to avoid penalties, stay in compliance, and remain competitive.

What To Do Now? Support Patients with Financial Flexibility

It’s becoming increasingly clear to hospitals and health systems that improving the patient financial experience is no longer optional – it’s essential. Not only for the benefit of their patients, but for their own economic stability. Providers benefit from offering patients affordable ways to pay their medical bills, and in some instances, is the only way their care will be compensated. Studies show that offering patients affordable, flexible payment options can significantly improve collections while also enhancing patient satisfaction and loyalty. Patients consistently favor financing options with no added interest when paying down medical expenses over time, which is one reason zero-interest options tend to outperform traditional payment plans or medical credit cards on patient satisfaction.

CarePayment helps hospitals and health systems bridge the gap between rising costs and patients’ ability to pay. CarePayment’s zero-interest, 0% APR, open-ended line of credit lets patients spread out their medical expenses over time, easing financial burdens and helping ensure timely access to care. See how it compares to zero-interest patient financing vs. medical credit cards. By adopting modern solutions like CarePayment, providers can improve their financial health while ensuring patients receive the care they deserve. Schedule a meeting to learn more about CarePayment’s  zero-interest patient financing solution.

Frequently Asked Questions

Why are so many medical bills going unpaid?
