Carrie L. Bashaw, Attorney General's Office, Olympia, for Respondent.
APPELWICK, J.
¶ 1 A settlement between Karine Paopao, a Medicaid recipient, and the State, negotiated as an accord and satisfaction in reasonable reliance on existing decisional law, is not subject to vacation based on a subsequent United States Supreme Court decision, mutual mistake of law or ultra vires agency action. We affirm.
Facts
¶ 2 On November 14, 2002, a car, driven by Juanita Salazar, struck Karine Paopao. Paopao suffered extensive injuries due to the accident. Because Paopao was unable to pay *643 her medical bills, she sought assistance from the Medicaid program administered by the Washington Department of Social and Health Services (DSHS). DSHS paid Paopao's medical expenses, totaling approximately $66,000.
¶ 3 In 2004, DSHS asserted a lien on any amount Paopao received from Salazar or her own insurance company. In May 2005, Paopao settled with Salazar's insurance company for $25,000. Paopao's own underinsured motorist coverage paid her $30,000. Paopao recovered a total of $55,000. The settlements were not apportioned between medical expenses and other losses.
¶ 4 DSHS initially sought reimbursement for the entire amount it expended for her medical expenses. After negotiations, DSHS and Paopao settled the Medicaid lien for $20,000. On November 3, 2005, Paopao sent final payment to DSHS. DSHS released the lien in February of 2006.
¶ 5 In May of 2006, the United States Supreme Court filed Arkansas Dept. of Health & Human Services v. Ahlborn, which limited a state's authority to assert and enforce a lien in excess of an amount representing medical expenses when a Medicaid recipient recovers from a third party tort-feasor.
¶ 6 Four months after the United States Supreme Court's decision in Ahlborn, Paopao filed a putative class action lawsuit in King County Superior Court, seeking damages, injunctive relief, and asserting a claim for a declaratory order based on unjust enrichment. Relying on the holding in Ahlborn, Paopao argued her settlement with DSHS was invalid and should be voided.
¶ 7 DSHS filed for summary judgment arguing Paopao's claims were barred by the doctrine of accord and satisfaction and that she failed to state a claim on which relief can be granted. Paopao in turn filed for partial summary judgment asking the court to find that Ahlborn can be applied retroactively, that DSHS' receipt of $20,000 from the negotiated settlement violated Ahlborn, DSHS' negotiation of the agreement was an ultra vires act, and that the statute of limitations had not run. After hearing oral arguments, the trial court granted summary judgment for DSHS and denied Paopao's motion. The trial court denied Paopao's request for reconsideration. Paopao appeals.
Discussion
A. Standard of Review
¶ 8 Paopao appeals the trial court's granting of summary judgment to DSHS. When reviewing a summary judgment order, the appellate court undertakes the same inquiry as the trial court. Thompson v. Peninsula Sch. Dist.,
B. Accord and Satisfaction
¶ 9 In 2005, the parties settled DSHS's claim for reimbursement of medical expenses from the amount Paopao received from the third party tort-feasor. DSHS asserts this agreement was an accord and satisfaction, which extinguished any claim Paopao had as to the validity of the lien.
¶ 10 Accord and satisfaction requires the parties have a bona fide dispute, an agreement to settle that dispute, and performance of the agreement. DAVID K. DEWOLF & KELLER W. ALLEN WASHINGTON PRACTICE: TORT LAW AND PRACTICE § 16.2 (3d ed.2007). An accord and satisfaction is a new contract a contract complete in itself. Evans v. Columbia Int'l Corp.,
¶ 11 We agree with DSHS that the parties reached an accord and satisfaction. The initial lien asserted by DSHS was disputed by Paopao. To resolve the dispute, the parties subsequently agreed to settle the claim for $20,000. Paopao performed on the agreement by tendering payment of $20,000 in November of 2005. The letter accompanying Paopao's payment stated "[t]his check represents full and final payment in settlement of all sums owing to date in full accord and satisfaction of all monies owed to you in payment of any and all liens DSHS, has against our client, Karine Paopao, for the above-referenced matter." (emphasis added). In turn, DSHS released the lien. There was no apparent reservation of rights or defenses on the underlying agreement. We hold that by performing on the agreement, which constitutes an accord and satisfaction, Paopao released her right to any claims and defenses under the original dispute.
C. Vacation and Retroactive Application of Ahlborn
¶ 12 Despite the accord and satisfaction reached by the parties, Paopao urges this court to retroactively apply Ahlborn and void her settlement with DSHS. Paopao argues that pursuant to Ahlborn, the settlement agreement is void because DSHS lacked legal authority to assert a claim on the portion of her recovery that represented more than medical expenses. DSHS therefore received more of her third party recovery than it was legally entitled.
¶ 13 In Ahlborn, the United States Supreme Court held that when a Medicaid recipient settles a tort claim against a third party, federal Medicare law prohibits a state from asserting a lien in excess of that portion of the settlement proceeds that represent medical expenses.
¶ 14 Paopao contends the Ahlborn decision requires vacation of her settlement agreement. Generally, only when a matter is still pending, is case law given retroactive effect. Reynoldsville Casket Co. v. Hyde,
¶ 15 Settlement agreements between private parties are viewed with finality. Or. Mut. Ins. Co. v. Barton,
¶ 16 In order to determine if the parties were justified in their reliance on prior case law, a court evaluates whether it had ever taken a position on a question of law and if the decisional law is a case of first impression. Bradbury,
¶ 17 Paopao however argues that DSHS was not justified in relying on Wilson, because the Eighth Circuit had expressly rejected its reasoning in 2005. Ahlborn v. Arkansas Dept. of Human Services,
¶ 18 We hold the settlement was entered into in reasonable reliance on Wilson, is final and should not be vacated. Ahlborn cannot be applied retroactivity under these facts.
D. Mutual Mistake
¶ 19 Paopao also argues this court should invalidate the agreement because both parties were mutually mistaken about DSHS's authority to assert a lien for the full amount of her third party recovery.
¶ 20 "A party seeking to rescind an agreement on the basis of mutual mistake must show by clear, cogent and convincing evidence that the mistake was independently made by both parties." Chemical Bank v. Wash. Public Power Supply Sys.,
(1) Where a mistake of both parties at the time a contract was made as to a basic assumption on which the contract was made has a material effect on the agreed exchange of performances, the contract is voidable by the adversely affected party unless he bears the risk of the mistake under the rule stated in § 154.
(2) In determining whether the mistake has a material effect on the agreed exchange of performances, account is taken of any relief by way of reformation, restitution, or otherwise.
In their briefs, both parties concede that based on Wilson, they believed the DSHS could assert a lien for Paopao's entire third party settlement. In 2005, when the parties settled, Wilson expressly permitted DSHS to assert a lien against a Medicaid recipient's third party recovery in excess of the portion representing medical costs. Wilson,
¶ 21 We hold there was no mutual mistake of law because the parties reasonably relied on controlling Washington law.
E. Ultra Vires
¶ 22 Based on Ahlborn, Paopao argues DSHS lacked the statutory authority to settle with her for more than the portion of the settlement representing medical expenses.
¶ 23 An administrative agency created by statute has only those powers expressly granted or necessarily implied by that statute. Properties Four, Inc. v. State,
¶ 24 DSHS has statutory authority to negotiate settlements. RCW 43.20B.050; RCW 43.20B.060. Pursuant to that authority it negotiated the settlement with Paopao. DSHS exercised this authority consistent with controlling decisional law with regard to the reach of its lien for reimbursement. We hold its actions were not ultra vires.
¶ 25 We affirm.

NOTES
Notes
[1] Paopao relies on Chemical Bank to suggest that the parties' mistaken belief about an agency's statutory authority constitutes a mistaken material assumption.
