N.C. Gen. Stat. § 36D-12
The Department shall adopt rules pursuant to Chapter 150B of the General Statutes governing the eligibility of beneficiaries for State medical assistance and State-County Special Assistance, and to supplement and expand upon the general requirements set forth in this Chapter, including, but not limited to, rules that may be more restrictive than the general requirements of this Chapter. With respect to Medicaid Pooled Trusts, a subaccount is irrevocable. The State shall be paid an amount up to the total medical assistance paid on behalf of the beneficiary by the Department from funds remaining in the individual trust subaccount upon the death of the beneficiary or termination of the trust as described in this Chapter. If the pooled trust is to be funded with the proceeds of a settlement of a lawsuit against a third party, the settlement proceeds are subject to the Department's subrogated rights of recovery as set forth in G.S. 108A-57, and all such subrogated rights of recovery shall be satisfied in full prior to execution and judicial approval of the trust, or both.
