Due to recent higher medical claim costs, an aging population and changes brought about by health care reform, employers can expect 2011 health care cost increases to be at their highest levels in five years, according to an analysis by Hewitt Associates, a global human resources consulting and outsourcing company. Next year, Hewitt projects an 8.8 percent average premium increase for employers, compared to 6.9 percent in 2010 and 6.0 percent in 2009. According to Hewitt’s analysis, the average total health care premium per employee for large companies will be $9,821 in 2011, up from $9,028 in 2010. The amount employees will be asked to contribute toward this cost is $2,209, or 22.5 percent of the total health care premium. This is up 12.4 percent from 2010, when employees contributed $1,966, or 21.8 percent of the total health care premium. Average employee out-of-pocket costs, such as copayments, coinsurance and deductibles, are expected to be $2,177 in 2011—a 12.5 percent increase from 2010 ($1,934). These projections mean that in a decade, total health care premiums will have more than doubled, from $4,083 in 2001 to $9,821 in 2011. Employees’ share of medical costs—including employee contributions and out-of-pocket costs—will have more than tripled, from $1,229 in 2001 to $4,386 in 2011. According to Hewitt, a variety of factors are driving the increase in projected health care cost increases for 2011. Employers are seeing an increase in the amount of charges and frequency of catastrophic claims. This is particularly true today, as slower levels of hiring have left employers with slightly older workforces who are more prone to costly medical conditions. Hewitt estimates that the most immediate applications of health care reform—including covering dependents to age 26 and the elimination of certain lifetime and annual limits—contributed approximately 1 percent to 2 percent of the 8.8 percent projected increase for 2011.
