In the United States, obligors may receive a medical order that requires them to add their children to their health insurance plans. In some states both parents are responsible for providing medical insurance for the child/children. If both parents possess health coverage, the child may be added to the more beneficial plan, or use one to supplement the other. Children of active or retired members of the U.S. armed forces are also eligible for health coverage as military dependents, and may be enrolled in the DEERS program at no cost to the obligor.
