Cuts to healthcare access harm us all

Like 155 million other Americans, I get my health insurance coverage through my employer.

The millions like me who are not on Medicaid or Medicare may not be closely tracking massive changes coming to public insurance programs because of H.R.1 (also known as President Donald Trump's "One Big Beautiful Bill Act"). But over the next decade, it's estimated that up to 10 million people may lose health insurance because of changes to Medicare and Medicaid.

And everyone is going to pay for it.

As associate chief medical officer of Covered California, I witness that health insurance coverage gains since the Affordable Care Act have resulted in more affordable healthcare, better health outcomes across a variety of conditions such as cancer and substance use disorder and saved tens of thousands of American lives.

In California, the uninsured rate dropped from 18% before the ACA to below 6% in 2024. Longstanding evidence shows that higher rates of health insurance coverage mean that more people have a front door to the healthcare system, access preventive and primary care, are protected against catastrophic costs from accidents or major diagnoses and are more likely to get the care they need for chronic conditions.

Unsurprisingly, the opposite is true when people lose health insurance coverage. Without health insurance, people seek care later, when they're sicker, and where it's more costly — in the emergency room.

Before the Affordable Care Act took effect and expanded health insurance access, I was a first year internal medicine resident working in the ICU. A woman in her 40s was admitted with a tumor visibly bursting out of her chest.

She had a cancerous breast mass that had grown so large and so destructive it had started to bleed, and the bleeding was finally what prompted her to go to the emergency room. She required extensive hospital care, and had very advanced cancer that, by the time she came to the hospital, could no longer be cured.

When I asked why she hadn't come in sooner she said she had nowhere to go and no way to pay for it. Since she had no health insurance coverage, she ignored the tumor on her body until it had started to weep.

When people without insurance seek care in emergency rooms, emergency rooms are required to care for them, even though no insurance company will pay the hospital for this care.

When doctors and hospitals can't get reimbursed enough to cover costs for patients without insurance, they rely on public funding sources to fill in the gap. With H.R. 1, these federal funding sources are being stripped away.

If they're not already doing so, doctors and hospitals may shift their gaze toward commercial health insurance companies to make up these costs. They may be forced to cut services, making it more difficult for those of us with insurance to access care.

As a doctor, I fear a regression back to that time in the ICU when patients came in seeking treatment later, when they were sicker.

I recognize that companies will need to find money to cover the costs for those people. Although H.R. 1 was designed to impact insurance for people with low incomes or certain immigration statuses, the cost will be all of ours to pay.

This issue may seem less pressing for Americans whose employers cover the cost of their health insurance or for those with very high incomes. But even the current healthcare workforce is stretched thin and there are only so many doctor's offices and hospital beds to go around. If they cannot keep their doors open, there won't be anywhere left to go.

And even though they're paying more each year, a shocking number of people don't take advantage of the health insurance coverage they have. One in five people with commercial health insurance coverage don't use it at all-- not one doctor's visit, flu shot, medication fill or screening test. And for young men age 18-34, that increases to one in three.

With changes due to H.R. 1 looming, it's especially important to understand the consequences. Though the changes may not have been aimed at all Americans, the cuts to healthcare access and coverage will have a ripple effect on us all.
