DETERMINING SUPPORT AMOUNT; MODIFICATION.

(a) The Title IV-D agency may use any information obtained by the agency from the parties or any other source and shall apply the child support guidelines provided by this code to determine the appropriate amount of child support. In determining the appropriate amount of child support, the agency may consider evidence of the factors a court is required to consider under Section 154.123(b), and, if the agency deviates from the guidelines in determining the amount of monthly child support, with or without the agreement of the parties, the child support review order must include the findings required to be made by a court under Section 154.130(b).

(b) If grounds exist for modification of a child support order under Subchapter E, Chapter 156, the Title IV-D agency may file an appropriate child support review order, including an order that has the effect of modifying an existing court or administrative order for child support without the necessity of filing a motion to modify.

(c) Notwithstanding Subsection (b), the Title IV-D agency may, at any time and without a showing of material and substantial change in the circumstances of the parties, file a child support review order that has the effect of modifying an existing order for child support to provide medical support or dental support for a child if the existing order does not provide health care coverage for the child as required under Section 154.182 or dental care coverage for the child as required under Section 154.1825.
