Wyo. Stat. § 7-9-115: Modification of order.

After a long-term physical health care restitution order has been entered, the court may from time to time, on the petition of either the defendant or the victim, or upon its own motion, modify the order as to the amount of monthly payments. Any modification of the order shall only be based upon a substantial change of circumstances relating to the cost of long-term physical health care or the financial condition of either the defendant or the victim. The petition shall be filed as part of the original criminal docket.
