1. An order of income withholding for health benefit plan coverage shall have priority over all other legal processes under state law against money, income or periodic earnings of the noncustodial parent except an order of income withholding for current child support.

2. Notwithstanding the provisions of section 452.350 and section 454.505, or any other provision of law to the contrary, the amount contained in an order of income withholding for health benefit plan coverage issued pursuant to sections 454.600 to 454.645, shall be considered a current child support obligation for purposes of applying the limitations contained in the federal Consumer Credit Protection Act, 15 U.S.C. § 1673(b), and shall run concurrently with orders issued pursuant to section 452.350 and section 454.505. However, when concurrently running wage withholding processes for the collection of support obligations, including an order for health benefit plan coverage, cause the amounts withheld from the obligor to exceed applicable wage withholding limitations, the employer shall not include the amount contained in the order of income withholding for health benefit plan coverage in determining the pro rata distribution, and shall not withhold any amount for health benefit plan coverage from an employee’s wages.
