One in three insured Americans carry medical debt despite paying for coverage

A new Commonwealth Fund survey finds that a third of Americans with private health insurance are still paying off medical debt, and many are draining savings or skipping meals to do it.

The report, released Thursday by the nonpartisan health policy research group, surveyed a nationally representative sample of 6,353 adults by telephone and online. Its central finding cuts against a basic assumption most working Americans hold: that having insurance means a hospital bill won't wreck your household budget. For roughly 33 percent of adults covered through an employer plan, an Affordable Care Act marketplace plan, or the private market, that assumption is wrong. They are carrying medical debt they are paying off over time.

The numbers get worse the deeper you look. Almost half of those with medical debt owe at least $2,000. Roughly 15 percent of all working-age, privately insured adults carry debt at that level or higher. Nearly two-thirds of adults with medical debt trace it to hospital visits, though routine care, doctor's office visits, lab work, diagnostic tests, also drives balances higher.

Families drain savings and cut back on food to cover bills

What happens after the bill arrives matters as much as the bill itself. Among those carrying medical debt, 37 percent said they drained their savings to pay it down. Thirty percent reported cutting back on basics like food, heat, or rent. Another 30 percent said they delayed or skipped medical care entirely, the kind of decision that can turn a manageable condition into an expensive emergency down the road.

Sara Collins, the study's lead author and a health economist at the Commonwealth Fund, told CBS News that the gap between what insurance covers and what patients actually owe is the core problem:

"The primary reason why these people have debt is about the extent to which their insurance covers their out-of-pocket costs."

That framing deserves a second look. These are not uninsured Americans showing up in emergency rooms. They are people who did what the system told them to do, signed up, paid premiums, carried a card in their wallet, and still got buried.

Low-income households hit hardest by unexpected bills

Collins pointed out that most Americans simply do not have cash on hand to absorb a surprise medical expense. A single bill landing in the wrong month can knock a family off a tight budget permanently.

"Most Americans don't have a lot of extra cash lying around, and when they are hit with an unexpected expense in a month when their income is allocated across all necessities of life, it can push people into medical debt they are unable to pay."

She was blunter about the effect on lower-income workers:

"Especially among people who are low-income, they are on pretty regimented household budgets, and medical bills can really tip that budget over into the realm of not being able to pay for certain things and having to cut back."

So a family paying premiums every month, money that could go toward groceries, a car payment, or a child's school supplies, still faces the prospect of choosing between a medical bill and the electric bill. The insurance they are paying for does not close the gap.

Consumers hesitate to fight back on billing errors

Collins noted that some patients are reluctant to dispute charges they suspect are wrong because they fear the process could damage their credit scores. Her advice was direct but acknowledged the difficulty: verify what you are being asked to pay, and contact insurers and providers to negotiate a payment plan when coverage is denied.

"It's a tough situation to be in, but it's important to make sure what you are being asked to pay is correct."

That guidance is practical as far as it goes. But it puts the burden squarely on the patient, the person least equipped to navigate opaque billing codes, insurer denials, and hospital finance departments. The system that created the debt is the same system the patient is told to call for help.

The survey did not detail how many consumers had attempted to dispute charges or what share succeeded. It also did not specify the margin of error for the 6,353-person sample or the time period during which the survey was conducted. Those gaps matter for anyone trying to measure the problem precisely, but the broad pattern is hard to dismiss: tens of millions of insured Americans owe money they did not expect to owe.

Insurance premiums keep rising while coverage gaps persist

The political promise behind the ACA marketplace, and behind employer-sponsored coverage more broadly, was that insurance would protect families from financial ruin when they got sick or hurt. By the Commonwealth Fund's numbers, that promise is falling short for a substantial share of the privately insured population. One in three is not a rounding error. It is a structural failure.

Hospital visits account for the largest share of debt, but the survey also flagged routine care as a contributor. That means the problem is not limited to catastrophic events. Ordinary checkups, lab panels, and diagnostic imaging are generating bills that insured patients cannot pay in full.

For working Americans who play by the rules, hold a job, carry coverage, show up for appointments, the reward is a system that still leaves them choosing between their health and their savings account. Washington spent years arguing about how to get people insured. The harder question, and the one these numbers force, is what that insurance is actually worth once you have it.
