The opinion of the court was delivered by: Bales, Justice.
¶ 1 The issue is whether an action to recover medical expenses for injuries to a child is time-barred. Revising Arizona's common law rule, we hold that both the minor and the minor's parents are entitled to recover pre-majority medical expenses, but double recovery is not permitted. Pearson & Dickerson Contractors, Inc. v. Harrington, 60 Ariz. 354, 137 P.2d 381 (1943), and S.A. Gerrard Co. v. Couch, 43 Ariz. 57, 29 P.2d 151 (1934), are overruled insofar as they hold that the right to recover belongs solely to the parents. Because the minor's action to recover medical expenses was timely under Arizona Revised Statutes ("A.R.S.") sections 12–502 and 12–821 (2010), we reverse the superior court's judgment dismissing that action.
¶ 2 On November 10, 2004, Maddison DeSela, then fifteen years old, sustained a life-threatening injury at Prescott High School. On January 31, 2005, Maddison's mother assigned to Maddison all claims for medical expenses incurred from the accident.
¶ 3 On March 22, 2005, Maddison filed a notice of claim with the Prescott Unified School District pursuant to A.R.S. § 12–821.01(A) (2010). This statute generally requires persons having claims against public entities or employees to file pre-litigation notices within 180 days after the claim accrues, but minors may file such notices within 180 days after turning eighteen. See A.R.S. § 12–821.01(D). Another statute sets a deadline for filing a lawsuit: "All actions against any public entity or public employee shall be brought within one year after the cause of action accrues and not afterward." A.R.S. § 12–821. A minor, however, may bring such an action that accrues during childhood within one year after turning eighteen. See A.R.S. § 12–502 (2010) (providing that minor or person of unsound mind "shall have the same time after removal of the disability which is allowed to others" to file suit).
¶ 4 Maddison turned eighteen on December 29, 2006. About six weeks later, a court-appointed conservator filed another notice of claim on Maddison's behalf. On December 31, 2007, Maddison's Estate filed this negligence action against the Prescott Unified School District and several school employees (collectively "PUSD"). This filing was within a judicial year of Maddison's eighteenth birthday because December 29, 2007, fell on a Saturday. The complaint sought damages for physical and emotional pain, disability, lost earnings, loss of enjoyment, and medical expenses. PUSD moved to dismiss the action for medical expenses, arguing that the cause of action originally belonged to Maddison's mother and was not brought within one year of its accrual, as required by A.R.S. § 12–821. The superior court granted the motion to dismiss and entered judgment under Arizona Rule of Civil Procedure 54(b).
¶ 5 The court of appeals reversed. Estate of DeSela v. Prescott Unified Sch. Dist., 224 Ariz. 202, 228 P.3d 938 (App.2010). Citing Pearson, the court noted that Arizona law has long held that a parent is the proper party to bring an action for medical expenses resulting from injuries to a child. Id. at 204 n. 4, ¶ 8, 228 P.3d at 940 n. 4. But Pearson also recognized that a parent can assign the right of recovery to the child. Pearson, 60 Ariz. at 364–65, 137 P.2d at 385. Here, Maddison was expressly assigned the claim for medical expenses on January 31, 2005, or eighty-two days after the accident. The court of appeals reasoned that the assignment triggered the tolling provision of A.R.S. § 12–502, and this statute allowed Maddison to bring the action for medical expenses within one year of her eighteenth birthday. Estate of DeSela, 224 Ariz. at 205 ¶ 13, 228 P.3d at 941.
¶ 6 PUSD petitioned for review, arguing that the court of appeals erred by applying § 12–502 to toll the limitations period for an assigned cause of action or, alternatively, by not subtracting eighty-two days from Maddison's one-year limitations period to reflect the time between the accrual of the action and its assignment. We granted review because determining the limitations period for recovery of medical expenses resulting from injuries to minors is an issue of statewide importance. We have jurisdiction under Article 6, Section 5(3) of the Arizona Constitution and A.R.S. § 12–120.24.
¶ 7 The court of appeals assumed, consistent with Pearson, that a parent is entitled to recover medical expenses for injury to the child, but the parent may assign the claim to the child. Estate of DeSela, 224 Ariz. at 204 ¶ 8, 228 P.3d at 940; cf. Webb v. Gittlen, 217 Ariz. 363, 366¶ 13, 174 P.3d 275, 278 (2008) (discussing assignment of causes of action). PUSD did not dispute the validity of the assignment. The parties understandably focused their arguments below on whether A.R.S. § 12–502 affects the running of the limitations period that would have applied, absent the assignment, to an action by Maddison's mother.
¶ 8 Before this Court, Maddison's Estate argued for the first time that Pearson should be reconsidered and that the right to recover medical expenses should belong to both the parent and child, provided that no double recovery may occur. Arguments raised initially in a supplemental brief are generally deemed waived. See Grand v. Nacchio, 225 Ariz. 171, 177 ¶ 33, 236 P.3d 398, 404 (2010). This rule, however, is a prudential one, and "we have made exceptions to consider questions that are of great public importance or likely to recur." In re Leon G., 200 Ariz. 298, 301 ¶ 8, 26 P.3d 481, 484 (2001), vacated on other grounds, Glick v. Arizona, 535 U.S. 982, 122 S.Ct. 1535, 152 L.Ed.2d 461 (2002). Moreover, the court of appeals was bound by Pearson and therefore unable to address its continued viability. Under the circumstances, we exercise our discretion to consider the merits of the Estate's arguments.
¶ 9 Pearson, decided in 1943, stated that in cases involving injury to a child, "the proper party to bring an action for ... the expenses of medical care and treatment [is] the parent and not the [injured] child." 60 Ariz. at 364, 137 P.2d at 385 (discussing Gerrard, 43 Ariz. at 66–67, 29 P.2d at 155). Explaining that this rule "is one intended to protect a defendant against having to pay such expenses a second time," the Court refused to apply it to bar a child's recovery of medical expenses when a parent had sued on the child's behalf as guardian ad litem. Id. The Court held that, in these circumstances, the parent was deemed as a matter of law to have assigned the action to the child, thereby allowing recovery in the child's name. Id. at 364–65, 137 P.2d at 385. The Court further noted that recovery of medical expenses by the child would preclude duplicate recovery by the parent. See id.
¶ 10 We agree that Pearson should be reconsidered insofar as it holds that, absent an assignment, the right to recover pre-majority medical expenses belongs to the parent and not the child. Pearson relied on Gerrard, which held that "ordinarily an infant suing for personal injuries cannot recover for the impairment of his earning capacity during infancy, or for loss of time, or for expenses in curing his injuries." 43 Ariz. at 67, 29 P.2d at 155 (quoting 31 Corpus Juris 1114, § 252). This rule reflected the notion that a minor's services and earnings "belonged to his parents," and therefore the damages claim for the child's injuries also belonged to the parents. Id. at 66, 29 P.2d at 155.
¶ 11 The underpinnings of Pearson and Gerrard have been eroded by the development of Arizona's common law. Gerrard treated the parent-child relationship in economic terms, much like the relation between master and servant. In determining tort liability for injuries to children, however, we have since observed that "the common law master-servant analogy is clearly antiquated and long overdue for judicial burial." Howard Frank, M.D., P.C. v. Superior Court, 150 Ariz. 228, 233, 722 P.2d 955, 960 (1986) (recognizing parents' cause of action for loss of consortium with adult child). Nor does avoiding double recovery, the only rationale identified in Pearson, justify characterizing an action to recover medical expenses for a minor's injuries as belonging solely to the parents. That concern can be addressed simply by denying double recovery for the same expenses, as Pearson itself recognized. Cf. Villareal v. ...
