(a) Health insurance that can be extended to cover the child is available to that parent through an employer or other organization; and

(b) The employer or other organization offering health insurance will contribute all or a part of the premium for coverage of the child.

(2) A parent who is required to extend insurance coverage to a child under this section is liable for any covered health care costs for which the parent receives direct payment from an insurer.
