Consumers would be able to shop for and compare insurance plans in a new purchasing exchange. Medicaid would be expanded, and limits would be placed on patients' yearly health care costs. The plan would be paid for with $507 billion in cuts to government health programs and $349 billion in new taxes and fees, including a tax on high-end insurance plans and fees charged to insurance companies and medical device manufacturers.
But the bill fails to fulfill President Barack Obama's aim of creating a new government-run insurance plan -- or option -- to compete with the private market. It proposes instead a system of nonprofit member-owned cooperatives, somewhat akin to electric co-ops that exist in some areas of the country. That was one of many concessions meant to win over Republicans.
In other ways, including its overall cost and payment mechanisms, the bill tracks closely with the priorities Obama laid out in his speech to Congress last week.
White House press secretary Robert Gibbs called the legislation an "important building block" that "gets us closer to comprehensive health care reform."
Baucus is still holding out hope for GOP support when his committee votes on the bill, probably as early as next week.
"This is a good bill. This is a balanced bill," he told reporters at a Capitol Hill news conference. Earlier, Senate Majority Leader Harry Reid, D-Nev., said, "Everyone should understand it's just the beginning, but it's a good beginning."
The measure represents the most moderate health care proposal in Congress so far, compared to legislation approved by three committees in the House and the Senate's health panel. Obama's top domestic priority is to revamp the health care system to provide coverage to nearly 50 million Americans who lack it and to rein in rising costs.
The bill includes provisions to keep illegal immigrants from obtaining health coverage through the new insurance exchanges -- reflecting the White House's newly stringent stance on the issue after a Republican House member interrupted Obama's speech last week to accuse him of lying about it.
The bill also would prevent federal funds from being used to pay for abortions except in cases of rape, incest, or if the life of the mother would be endangered. It's all but certain that the Baucus provisions will not be the last word on either of those volatile issues.
The bill would set up a verification system to make sure people buying insurance in the exchanges are U.S. citizens or legal immigrants, using Social Security data and Homeland Security Department files. The bill would impose penalties for fraud and identity theft.
While only legal residents would be able to buy coverage through the exchanges, illegal immigrant parents would be able to get insurance for their U.S. born children.
The bill would prohibit abortion from being included in any minimum benefits package. However, plans in the exchange could offer unrestricted coverage for abortions, provided that no funds from government subsidies are used to pay for them. Women who want coverage for abortions would have to pay for it with their own money.
Wednesday's bill release follows months of negotiations among Baucus and five other Finance Committee senators dubbed the "Gang of Six" -- Republicans Chuck Grassley of Iowa, Mike Enzi of Wyoming and Olympia Snowe of Maine, and Democrats Kent Conrad of North Dakota and Jeff Bingaman of New Mexico.
Enzi said he couldn't support the Baucus bill and preferred an incremental approach.
In the end, Democrats believe Snowe may be the only Republican to support the bill, though she wasn't ready to commit her support.
"This is a first step in the process," Snowe said as she promised to continue to work with Baucus and Democrats on coming up with bipartisan legislation.
The bill drew quick criticism from Republican leaders.
