How does the age 26 regulation change when the adult dependent is eligible for other coverage?
Plans that offer dependent coverage must make that coverage available until the child reaches age 26. This applies to married and unmarried children, as well as children that have other coverage available to them. The only exception is for grandfathered plans, which are not required to continue coverage if the child has access to coverage through his employer; however, this exception will no longer apply beginning 2014.
