This paper reports changes in job-based health insurance from spring 2002 to spring 2003. The cost of health insurance rose 13.9 percent, the highest rate of increase since 1990. Employers required larger contributions from employees for the monthly cost of health insurance. Separate copayments and deductibles for hospital services have become commonplace, and provider networks have broadened. There was no change in the percentage of employers offering health plans to their workers. Employers indicate little confidence in any future strategies for controlling health care costs.
