When Does Health Insurance Coverage End For Dependent Children? 
In most cases , dependent children will `` age off '' their parents plan once they reach their 26th birthday . If your child is severely disabled they may qualify for continuing coverage as a dependent . If your child is healthy , they may be better off with their own health insurance policy regardless of their age . Keep in mind that child only policies for children under the age of 19 do not exist in most states .
