The Scale of Medical Debt in America

Roughly one in five American adults — somewhere between 40 and 50 million people — report having unpaid medical bills or debt they are actively paying down. The exact number shifts depending on which survey you look at and how the question is worded, but every major study finds the same pattern: medical debt touches a significant portion of the country, not a small fringe.

The KFF Health Insurance Coverage Survey and the Federal Reserve's Survey of Household Economics and Decisionmaking are the two most widely cited sources. Both track this regularly, and both show that medical debt has remained stubbornly high even in years when the economy was growing. This is not a temporary spike tied to a single event — it is a persistent feature of how Americans pay for healthcare.

Medical debt also shows up on credit reports and in collections data. The Consumer Financial Protection Bureau has found that medical debt accounts for a large share of debt in collections, though the exact percentage varies by region and year. What matters for your situation is that if you have unpaid medical bills, you are far from alone.

Key Takeaways

  • Between 40 and 50 million American adults report having unpaid medical bills or active medical debt, based on surveys from the Federal Reserve and KFF.
  • Medical debt is the leading cause of personal bankruptcy in the United States, even for people with health insurance.
  • Medical debt appears on credit reports and can be sold to collection agencies, affecting your credit score and payment history.
  • The amount of medical debt varies widely by age, income, and whether someone has insurance — but it crosses all income levels.

Who Carries Medical Debt and Why

Medical debt is not limited to uninsured people. Roughly half of Americans with medical debt actually have health insurance at the time the debt forms. This happens because insurance does not cover everything — deductibles, copays, and out-of-pocket maximums still leave patients responsible for large bills. A single serious illness or injury can push someone past their out-of-pocket limit and into debt even with a policy in place.

Younger adults (ages 18 to 44) and middle-income households report medical debt at higher rates than you might expect. Younger people often have high-deductible plans to keep premiums low, which means they pay more out of pocket. Middle-income households earn too much to may have access to for Medicaid in most states but not enough to absorb a major medical bill without strain.

Older adults and lower-income households also carry medical debt, though sometimes for different reasons. Seniors on Medicare still face copays and premiums, and prescription costs can add up. Lower-income households may lack insurance altogether or have gaps in coverage, making any medical event a financial crisis.

Medical Debt and Credit Reports

If you do not pay a medical bill, the provider or a collection agency can report it to the three major credit bureaus — Equifax, Experian, and TransUnion. Once it appears on your credit report, it can lower your credit score and stay there for up to seven years from the date of first delinquency, even if you pay it later.

The Consumer Financial Protection Bureau has pushed for stricter rules around medical debt reporting, and some changes have taken effect. As of 2024, paid medical debt no longer appears on credit reports in most cases, and unpaid medical debt may not be reported until it is at least 180 days past due. However, rules vary by state and by creditor, so the safest assumption is that unpaid medical bills will eventually reach your credit file.

If a medical debt goes to a collection agency, the collector can contact you by phone, mail, or email. They can also sue you in court if the debt is large enough. Understanding your rights under the Fair Debt Collection Practices Act can help you respond appropriately if this happens.

Medical Debt as a Cause of Bankruptcy

Medical issues are the leading reason Americans file for bankruptcy — more common than job loss, divorce, or credit card debt alone. Studies suggest that medical bills or medical events contribute to between 40 and 66 percent of all personal bankruptcies, depending on how the research defines "medical bankruptcy."

Bankruptcy is not the only outcome, but it shows how severe medical debt can become. Many people instead fall behind on other bills, drain savings, or take on additional debt to cover medical costs. Some delay or skip medical care because they cannot afford it, which can make their health worse and create even larger bills down the road.

Regional and Income Differences

Medical debt is not evenly distributed across the country. States with higher uninsured rates, lower Medicaid coverage, or higher healthcare costs tend to have more residents reporting medical debt. Rural areas sometimes face higher costs because fewer providers compete on price, and transportation to care can add expenses.

Income matters significantly. Households earning under $40,000 per year report medical debt at much higher rates than those earning over $100,000. However, even high-income households can face medical debt if they encounter a catastrophic illness or injury that exhausts their insurance coverage and savings.

What Happens to Unpaid Medical Bills

When you receive a medical bill you cannot pay, the provider typically sends statements for 30 to 90 days. If you do not respond or pay, the account may be sent to an internal collection department or sold to a third-party collection agency. At that point, the debt can appear on your credit report and collection calls may begin.

Some providers offer payment plans or financial hardship programs that let you pay over time without interest or with reduced interest. Asking about these options before the bill goes to collections is usually your best move. Many hospitals and large medical practices have financial counselors who can discuss options with you.

If a collection agency buys your debt, you have rights under federal law. You can request verification that the debt is actually yours, dispute inaccurate amounts, and ask the collector to stop contacting you. Paying a collection account does not remove it from your credit report when ready, but it does stop future collection activity.

How Medical Debt Differs From Other Debt

Medical debt is treated differently in some ways. It typically has no interest (unlike credit cards), and some states have laws that limit what medical providers can do to collect. However, medical debt can still be sold to collection agencies, reported to credit bureaus, and pursued in court — so it carries real consequences even without interest charges.

The Fair Credit Reporting Act governs how medical debt appears on your credit report, and recent changes have made medical debt less damaging to your score than it was in the past. However, the damage is still real, and unpaid medical debt can affect your ability to rent an apartment, get a loan, or even land a job in some fields.

Frequently Asked Questions

Can medical debt be forgiven or written off?

Some hospitals and providers will negotiate a settlement for less than the full amount owed, especially if you contact them before the debt goes to collections. Nonprofits and patient advocacy groups sometimes help pay medical bills for people in financial hardship. However, forgiveness is not automatic — you have to ask and often provide proof of financial need.

Does medical debt affect your credit score the same way credit card debt does?

Medical debt does lower your credit score when it appears on your report, but recent changes have made it less damaging than credit card debt. Paid medical debt no longer shows up on most credit reports, and unpaid medical debt may not be reported until it is significantly past due. Credit card debt, by contrast, can be reported as soon as it is 30 days late.

What should I do if I get a bill I cannot pay right now?

Contact the provider's billing department or financial counselor before the bill goes to collections. Ask about payment plans, financial hardship programs, or charity care. If you cannot reach an agreement, keep records of your attempts to pay and any communication with the provider — this can help if the debt later goes to a collection agency.

Can a medical provider sue me for unpaid bills?

Yes, medical providers and collection agencies can sue you in court if the debt is large enough to justify the cost. If they win, they can garnish your wages or place a lien on your property, depending on your state's laws. This is another reason to contact the provider early and try to work out a payment arrangement.

How long does medical debt stay on your credit report?

Medical debt can remain on your credit report for up to seven years from the date you first fell behind on the bill. However, if you pay the debt, it will stop being reported as active, and paid medical debt no longer appears on most credit reports as of 2024.
