A surge in Medicaid enrollment during the coronavirus pandemic is pushing the United States near a momentous tipping point: More people getting health care coverage through a government plan than through the private sector.

Here’s the math. A record 80.5 million Americans now get health coverage through Medicaid and a related program for children. Another 64 million are Medicare enrollees. The Affordable Care Act covers about 13 million Americans, the Pentagon’s Tricare system 9.6 million, and the Veterans Administration another 9 million. There are some duplicates, such as 11 million people who get both Medicaid and Medicare, and others who have coverage through the military as well as another plan. At a minimum, about 150 million Americans get coverage through a government plan, and the number could be several million higher.

Private-sector companies covered 158 million Americans in 2019, but job losses during the coronavirus pandemic probably cut that to around 153 million, including dependents. So the number of people covered through a company plan is very close to those covered by the government. Another 5 million or so buy private coverage on their own, with no government aid, but new federal subsidies in this part of the market will probably cut that number, too.

“Our system is not nearly as private as people might think,” says Larry Levitt, executive vice president at the Kaiser Family Foundation. “The government plays a huge role in our health care system. We’re at or very close to the point where more people are getting coverage sponsored by the government than by employers.”

Government-backed health care is not the “socialized medicine” critics associate with endless waits and shoddy care. Private-sector doctors and nurses still provide most of the care in the United States, even when Uncle Sam covers the cost. Managed care providers and health insurers still operate as middlemen in programs such as Medicare Advantage and the Affordable Care Act exchanges. The government increasingly foots the bill, however, as policymakers have offered new programs for the millions who fall through the cracks of the traditional employer-based health care framework.

The Affordable Care Act, which Congress passed in 2010, now provides coverage to 31 million Americans, through the federal and state exchanges and also through broader eligibility for Medicaid. Three Republican-backed lawsuits trying to kill the law made it to the Supreme Court, where all three failed, including the latest smackdown on June 17. The law’s durability, along with its increasing popularity, may embolden Democrats to try enacting other government health care plans.
