Yes, you may buy a child-only coverage for your daughter, either on or off the exchange. In 2010, neither of these were applied to children—there was no obligation that parents maintain health insurance for their children, and there were no subsidies to assist pay for coverage. Any child under 18 could be left without coverage if his or her parent(s) chose not to purchase insurance. In addition, children can sometimes be excluded from family coverage if one of them has been determined to be "eligible for other coverage." For example, if one's employer provides coverage through an association such as a labor union or employees' benefit trust, then that person would be able to exclude their children from that coverage by claiming eligibility for another policy. Further, if a child has been deemed "dependent" on a tax return because he or she receives more than one-half of his or her support from his or her parents, then that child would be eligible to receive coverage through our system even if his or her parents did not want to purchase insurance for him or her. Finally, if a child does not meet the minimum age requirement for being covered under his or her parent's plan (which is usually 19 for men and 20 for women), then that child would not be able to join that plan even if he or she wanted to.
