While people over 65 are more likely to have health problems, they have access to health insurance coverage through the federal Medicare program, Ms. McKernan said. Baby boomers are also more likely to have health insurance, which may contribute to their lower rates of medical debt.
The higher proportion of younger adults with medical debt was a bit surprising, Ms. McKernan said, because they tend to have fewer health problems. But they are less likely to have health insurance, she noted, and have not been accumulating wealth as quickly as earlier generations.
Millennials also tend to have a lower level of financial knowledge, which may make them more vulnerable to medical debt, another institute analysis found.
Congress is debating repealing and replacing the Affordable Care Act, commonly known as Obamacare, spurring concerns that more Americans may lose health coverage and become more vulnerable to medical debt. People with health insurance are less likely to have medical debt, but even those with health coverage have trouble paying medical bills on time, institute researchers noted.
Here are some questions and answers about medical debt:
How can I avoid medical debt?
The high level of medical debt among young adults, Ms. McKernan said, is an argument for buying health insurance, even if you feel you don’t need it. “Get health insurance, even if you’re young,” she said. A health plan may not cover every cost incurred, she said, “but it sure helps.”
Likewise, she said, even a modest emergency savings account — say, between $250 and $750 — can help cover unexpected bills. A recent analysis by the JPMorgan Chase & Co. Institute found that 16 percent of American families had paid at least one “extraordinary” medical bill, typically of just over $1,100, from 2013 to 2015.
Caitlin Donovan, director of outreach for the National Patient Advocate Foundation, urged consumers to look beyond monthly premiums when choosing a health plan; deductibles, co-payments and other out-of-pocket costs can add up quickly when you need care.
How can I manage medical debt?
If you get a medical bill that’s unexpectedly large, don’t ignore it — doing so may mean that the bill is sent to a collections agency, where it can dent your credit history, Ms. Donovan said. Start by asking your provider for an itemized bill, she suggested, to check that you were not mistakenly charged for services you didn’t receive.
Particularly if your insurer has denied coverage, call and ask whether the provider used the correct billing codes. “Ask, ‘What code needs to be used to have this covered?'” she said. Be polite, Ms. Donovan advised, but don’t be put off: “It’s not an unreasonable thing to ask.”
