Under a plan proposed by Senator Bernie Sanders of Vermont on Wednesday, all Americans would get government-funded health insurance: “Medicare for all.” What that would mean for you as a consumer depends on whether you currently have insurance, and if so how you’re covered.

The plan would also have big effects on the health care industry, since it would eliminate private health insurance and change the way medical providers and drug companies are paid.

group Doctors and hospitals would probably face pay cuts, but would no longer face unpaid bills. Drug companies would most likely have smaller profits. Health insurance companies would mostly be eliminated.

With Republicans in control of the Senate, the plan has no chance of becoming law anytime soon, but its co-sponsors include several Democratic presidential hopefuls, including Mr. Sanders, meaning it will feature in the policy debates of the 2020 election.

The Sanders legislation leaves certain things unclear, including how the plan would be financed. Here’s a general sense of the spectrum of changes for different groups of consumers, and for the health care industry, which makes up 18 percent of the nation’s gross domestic product.

People insured through work

New taxes, but no more premiums.

The employer-based insurance that now covers 156 million people would be eliminated. Those people would lose their current coverage and be enrolled in the new program instead.

Both employers and workers would probably face new taxes to pay for the coverage but would not have to pay the premiums or deductibles they’re paying now.

For some people, the tax increases could be lower than current premium costs, but not necessarily for everyone. Without a detailed financing plan, it’s impossible to say for sure.

People with Medicaid

More choices, but possibly higher taxes.

Medicaid would be eliminated, and everyone who currently gets medical benefits from Medicaid — about 73 million people — would switch to the new single-payer system. They now pay very low fees when they receive medical care, and that would not change much.

But the current Medicaid beneficiaries would probably gain access to more choices of doctors and hospitals in the new program. Some who work might need to pay higher payroll taxes.

The part of Medicaid that currently pays for institutional long-term care, like nursing homes, would remain in place. That means that some Medicaid beneficiaries would be enrolled in both programs. Other kinds of long-term care, such as home-based services, would become part of the new Medicare system.

People with Medicare

More generous coverage.

Medicare is now available to about 61 million people age 65 and older and to some younger people with disabilities. Coverage for these people would become more generous because the Sanders bill would expand to cover dental, vision and hearing aids, which are not covered under current law.

The bill would also get rid of nearly all cost-sharing requirements in the program. Beneficiaries could go to the doctor or hospital without having to pay any money out of their pocket. The program would require co-payments for certain prescription drugs.

Currently, Medicare beneficiaries pay premiums every year to be enrolled in the program. Those would go away. But the overhaul would also eliminate private Medicare Advantage health plans, which enroll more than a third of beneficiaries, bringing all beneficiaries into the government program.

The uninsured

All get health care.

Around 28 million uninsured Americans would be able to obtain coverage through the new universal Medicare for all program, within four years of the bill’s passage. Children could join right away, and any American 55 or older could join traditional Medicare, if they paid premiums.

People who buy their own insurance

New taxes, less out-of-pocket spending.

The 21 million people who currently buy their own coverage, either in the Obamacare marketplaces or directly from insurance companies, would instead get Medicare. The Affordable Care Act exchanges would be eliminated.

It’s unclear if new taxes would make it cheaper or costlier for this group. For many, coverage under the new program would involve substantially less out-of-pocket spending and would permit access to a wider choice of doctors and hospitals.

Veterans and Native Americans

Keep existing system.

The more than 9 million veterans who get their health care from the Veterans Administration health care system would be able to preserve that access for at least 10 years.

About 2 million Native Americans who use the Indian Health Service could also keep their current source of care for at least 10 years.

These two government programs would be the only forms of health insurance not substantially changed by the bill.

Doctors and hospitals

Pay cuts likely, but no more unpaid bills.

Doctors and hospitals may have to take pay cuts, since the current Medicare program typically pays them less than commercial insurers pay for the same services.

But the bill’s expansion of coverage means that hospitals and doctors would no longer need to worry about unpaid bills from patients who lack insurance or can’t afford to pay their insurance deductible. They may also save on administrative costs, since they would not need to interact with as many insurers or to bill patients for services.

The bill does not specify exactly what doctors and hospitals would be paid, and the effects would depend on those details. But decreases and changes in payment policy could cause changes to the business of health care as hospitals, doctors, nurses and others adjust to lower payment rates and salaries.

Universal Medicare-like payment rates would almost certainly cause some major disruptions, like hospital closings.

Drug companies

Less profit.

Drug companies would most likely earn substantially less from American patients under this system. The new Medicare system would negotiate with drug companies on behalf of all Americans, and would deny coverage of drugs that cost too much. That policy would probably reduce prices paid to pharmaceutical companies, bringing them closer to what other large government systems pay.

Those reductions could have ripple effects, lowering the profitability of the pharmaceutical sector and discouraging investments in new medicines.

Insurance companies

Would mostly be eliminated.

Because everyone would eventually get insurance from Medicare, private insurance companies would essentially be eliminated. The bill would bar employers from offering private insurance once the new system becomes universal.
