(a) An obligor ordered to provide health insurance coverage or dental insurance coverage for a child must notify the obligee and any child support agency enforcing a support obligation against the obligor of the:
(1) termination or lapse of health insurance coverage or dental insurance coverage for the child not later than the 15th day after the date of a termination or lapse; and
(2) availability of additional health insurance or dental insurance to the obligor for the child after a termination or lapse of coverage not later than the 15th day after the date the insurance becomes available.
(b) If termination of coverage results from a change of employers, the obligor, the obligee, or the child support agency may send the new employer a copy of the order requiring the employee to provide health insurance or dental insurance for a child or notice of the medical support order or the dental support order as provided by this subchapter.
