WASHINGTON , JULY 30, 2009 -- An estimated 4.1 million residents in Pennsylvania could lose their private, employer-based coverage if Congress passes a House health reform bill, according to state-specific analysis of The American Affordable Health Choices Act of 2009 released this week by The Heritage Foundation.

Heritage commissioned The Lewin Group, a highly respected health care policy and management consulting firm, to examine the impact a newly created government-run health plan within the House bill would have on Americans with private health insurance, including employer-based coverage, as well as its impact on Pennsylvania's doctors and hospitals.

In addition to examining the national impact, Lewin analyzed several states including Pennsylvania to show how the major regions of the United States would be affected. Lewin's estimates assume that all employers in the state become eligible for enrollment in the new public plan and health insurance exchange starting in the third year of implementation.

Of the estimated 7.6 million Pennsylvanians with private health insurance, 51 percent would transition out of private coverage, Lewin reports. Plus, 59 percent of the state's population who get their private insurance from the workplace could have their existing coverage change or disappear under the House health bill.

"The data highlights the nasty, unintended consequences a government-run health insurance plan could have on states," said Heritage Vice President Stuart Butler. "Many employees will be pushed into a public plan as employers respond to the legislation's incentives to drop coverage."

Another key finding from Lewin:

• 32 percent of Pennslvania's uninsured population would still lack coverage. Of the estimated 1.4 million people without health coverage, the legislation would only reduce the uninsured by 952,600, leaving 447,400 Pennsylvania residents without coverage.
