100 Million Americans Owe Medical Debt (2026 Data)

Ask "how many Americans have medical debt" and you will get four different numbers from four credible sources, ranging from 15 million to 100 million. All of them are correct. They measure different things, and the gap between them tells you more about how medical debt works than any single figure could.

Here is how each count is built, which one describes your situation, and why the largest number is the honest one.

How many Americans have medical debt? It depends on the count

Four numbers survive scrutiny because "medical debt" can mean a hospital bill in collections, a credit card balance from a pharmacy, or a loan from your sister, and each dataset draws the line in a different place.

The Census-based figure is the one you see cited as "20 million Americans owe $220 billion." It is conservative on purpose. It ignores anyone who paid a $3,000 emergency room bill with a credit card and is now paying 24% interest on it, because that debt shows up in the data as credit card debt. It ignores the person who borrowed from a parent. It ignores the bill under $250.

The KFF survey asks the question a household would ask: do you owe money because of medical care? Four in ten adults said yes. That is the number that describes life as people live it, and it works out to about 100 million people.

How much medical debt do Americans owe?

At least $220 billion in unpaid medical bills, per KFF's analysis of Census data, and that floor sits well below the real figure for the reasons above.

The distribution matters as much as the total. Most people who owe medical debt owe less than a few thousand dollars, which sounds manageable until you remember that the Federal Reserve's household survey has found for years that a large share of adults could not cover a $400 emergency without borrowing. A $1,200 hospital bill is not a rounding error for those households. It is the emergency.

At the other end, KFF's analysis found about 3 million people owe more than $10,000 in medical debt. Those balances come from the events insurance is supposed to protect against: a cancer diagnosis, a premature birth, a car accident with an out-of-network surgeon. For that group, medical bankruptcy is a live option, and the fact that the United States is the only wealthy country where that phrase has meaning is the point.

Who carries the most medical debt?

The people with the least room to absorb it, in the places with the fewest protections.

Geography comes first. The Urban Institute's county-level data shows the highest rates of medical debt in collections concentrated across the South, with Texas, Oklahoma, Mississippi, and the Carolinas well above the national rate, and the lowest rates in the Northeast and Upper Midwest. The map tracks two policies: whether the state expanded Medicaid under the Affordable Care Act, and whether the state regulates hospital collections. Ten states have still not expanded Medicaid as of 2024, and their residents carry medical debt at higher rates.

Race comes next. KFF found Black adults report health care debt at a higher rate than white adults, a gap that persists after adjusting for income and reflects both lower rates of coverage and the concentration of Black households in non-expansion states.

Then the categories you would expect: the uninsured, people with disabilities, parents of young children, and adults with high-deductible health plans whose insurance does not start paying until they have spent several thousand dollars. And one you might not expect: most people with medical debt had insurance when the bill was generated. Coverage in the United States reduces the size of the bill. It does not stop the bill from arriving.

Did the credit report changes fix anything?

They removed a lot of small debts from credit files. They did not remove the debts.

Starting in 2022, Equifax, Experian, and TransUnion dropped paid medical collections and any medical collection under $500, which wiped out a majority of medical collection line items by count. The Consumer Financial Protection Bureau estimated in 2024 that about 15 million people still had roughly $49 billion in medical collections on their reports, and issued a rule in January 2025 to remove all of it. A federal court vacated that rule later in 2025.

So the answer to whether a medical bill affects your credit is now a function of the bill's size and your state. Colorado, New York, California, Minnesota, and a growing list of states ban medical debt from credit reports outright. Elsewhere, a $600 collection can still cost you a mortgage rate.

None of this changes what you owe. The collector can still call, sue, and garnish in most states. The credit report was the visible symptom; the debt is the disease.

Why does the richest country produce this much medical debt?

The United States is the only rich country that bills patients this way.

Peer nations have deductibles, copays, and waiting lists. None has a secondary market where hospital receivables sell to debt buyers for pennies on the dollar, because none lets a hospital bill an individual patient $40,000 for a night in intensive care. In Germany, France, Japan, and Canada, the concept of medical bankruptcy does not exist in the statistics because the underlying bill does not exist.

The American version stacks three things. Hospital prices set by the seller with no functioning market, which is why healthcare costs so much here. Insurance built to cap the insurer's exposure through deductibles and networks, so that an emergency room visit generates a bill even with a card in your wallet. And wages that stopped growing decades ago, so that a bill of a few thousand dollars lands on a household with a few hundred in savings.

Each of the 100 million people in the KFF count sits at the intersection of those three. Roughly 20 million of them owe enough that the government's own statisticians noticed. The rest are paying a pharmacy bill on a credit card at 24% and do not appear in anyone's total.

The number is the policy

Counting medical debt is not a measurement problem. It is a description of a choice. The United States decided that patients would be billed at the point of care, that insurance would leave a gap, and that the gap would be the household's problem. The size of the resulting debt, whether you use the 20 million figure or the 100 million one, is the price of that decision, paid by people who never made it.

Every other affordability failure in this country has the same shape: a cost that rose, a wage that did not, and a family that absorbed the difference. The federal minimum wage has been $7.25 an hour since 2009. A single ambulance ride costs more than a week of that. The full ledger of what a hospital visit does to a working household is in medical debt in America, what it does to your head and your health is in medical debt and mental health, and how many people are one diagnosis from joining the count is in how many Americans still have no insurance. The whole picture belongs in the American dream is broken.
