@lafialali So he's correct and OP cannot remain on his father's policy. He brought up disability since that's the only way and OP is not legally disabled.
@truthseeker522 The only exception I can think of is COBRA - people can stay on their parent's plans until age 29 if they're willing to go this route. Of course, it's probably the most expensive coverage option OP would qualify for.
@truthseeker522 Straight up false regardless of your bs about a disability, due to the fact that some states (NJ, FL, and PA, for example) allow the child to stay on the parents' insurance past 26 depending on various factors like full-time student status, or if they're unmarried. Choosing PA at random, if OP lived there they could stay on the insurance until they're 30 so long as they all live in PA and OP doesn't get married. Don't have to be a student or anything. Just have to file a request.
