Average premiums in the FEHB plan will rise 2.1 percent in 2008, the second straight year of minimal increases overall, OPM has said, although as in the past there will be significant variation among plans. Due to accounting rules, the average enrollee share will be up by 2.9 percent. Increases have been moderating steadily since the 12.7 percent average for 2002 over 2001, with the actual average increase for 2007 over 2006 working out to be 1.6 percent. The average biweekly enrollee premium will rise by $1.58 to $59.69 for self-only coverage and by $4.11 to $135.13 for family coverage. However, premiums in the largest plan, Blue Cross-Blue Shield Standard—which has about half of all FEHB enrollees—will increase by more than 8 percent. Nine-tenths of enrollees will see an increase of less than 10 percent and a third will see an increase of less than 5 percent, officials said.
