Nearly half of all Americans with employer-based health insurance plans say more money is being taken out of their paychecks for health insurance compared to a year ago, and 44% are facing higher out-of-pocket expenses, including deductibles and copayment, according to a report by the Princeton Survey Research Assocs. International and Bankrate.com.

Americans with annual household incomes between $50,000 and $74,999 with employer-based health insurance have been impacted most: 47% of respondents in this demographic report a negative effect on their health insurance, a much higher percentage than any other income level.

“Since so much of the Obamacare conversation has focused on uninsured Americans and the government-run exchanges, it's easy to forget most Americans—about 150 million—get their health insurance from an employer,” said Bankrate.com insurance analyst Doug Whiteman.
