a. To the extent permitted under 42 U.S.C. §666(a)(10)(A)(i)(II), the cost-of-living alteration shall be an exception to any requirement under law for the application of the child support guidelines established pursuant to section 598.21B, including but not limited to any requirement in this chapter or chapter 234, 252A, 252B, 252C, 252F, 598, or 600B.
