California’s government would set prices for hospital stays, doctor visits and other health care services under legislation introduced Monday, vastly remaking the industry in a bid to lower health care costs.

The proposal, which drew swift opposition from the health care industry, comes amid a fierce debate in California as activists on the left push aggressively for a system that would provide government-funded insurance for everyone in the state.

Across the country, rising health care costs have put the industry, lawmaker and employers and consumers at odds.

Oregon aggressively expanded its Medicaid rolls under the Affordable Care Act, adding enough people to leave only 5 percent of its population uninsured — one of America’s lowest rates.

Now, with the reduction of a federal match that covered those enrollees, the state is calling on voters to decide how to pay for its ballooning Medicaid costs.

A special election on Tuesday asks Oregonians whether they approve of a tax on hospitals, health insurers and managed care companies that would leave Medicaid, as it is now, untouched. More than 1 in 4 residents here rely on it.
