The limit on out-of-pocket costs, including deductibles and co-payments, was not supposed to exceed $6,350 for an individual and $12,700 for a family. But under a little-noticed ruling, federal officials have granted a one-year grace period to some insurers, allowing them to set higher limits, or no limit at all on some costs, in 2014.
