(a) If a child’s eligibility for dependent health or dental coverage ends because the parent ceases to be eligible for the coverage and the coverage provides for the continuation or conversion of the coverage for the child, the benefit plan issuer shall notify the custodial parent and the child support agency of the costs and other requirements for continuing or converting the coverage.
(b) The benefit plan issuer shall, on application of a parent of the child, a child support agency, or the child, enroll or continue enrollment of a child whose eligibility for coverage ended under Subsection (a).
