Some members of Congress are about to get their own kind of sticker shock when they head to the new insurance exchanges. A few will get a price cut. As the Journal has reported, a provision in the health law requires lawmakers to get their benefits alongside small-business employees for the first time, and that means lawmakers’ premiums will suddenly be tied to their age.

Members of Congress used to pay the same rate, regardless of how old they were, which was around $186 a month to cover just themselves on one popular plan after their employer (in this case, the federal government) kicked in a 75% contribution. They paid more –$434 — for a family plan, which covered a spouse and any number of children.
