OPINION

Chief Judge Randall M. Howe delivered the Opinion of the Court, in which Presiding Judge Cynthia J. Bailey and Judge Andrew M. Jacobs joined.

H O W E, Judge:

¶1 Petitioner Maricopa County Special Health Care District, doing business as Valleywise Health Medical Center, petitions for special action relief from the denial of its motion to dismiss Respondent Peggy Jackson’s Adult Protective Services Act (“APSA”) claim. Valleywise contends that the superior court erred because (1) Valleywise is not a “person” or “enterprise” subject to suit under APSA, and (2) Jackson’s notice of claim did not place Valleywise on notice of her APSA claim. Whether a special health care district is subject to suit under APSA is a legal question of first impression. See Ariz. R.P. Spec. Act. 12(b)(3). It is also likely to recur, and is thus of statewide importance. See Ariz. R.P. Spec. Act. 12(b)(4). Although “[g]enerally, special action review of a denial of a motion to dismiss is not appropriate,” Farmers Ins. Exch. v. Udall, 245 Ariz. 19, 21 ¶ 6 (App. 2018), the issues here are not “ordinary dispositive motion practice,” and accepting jurisdiction “will materially advance the efficient management of the case,” see Ariz. R.P. Spec. Act. 12(b)(7). Thus, we accept jurisdiction. We deny relief, however, because a special health care district is subject to suit under APSA and Jackson’s notice of claim sufficiently placed Valleywise on notice of its potential liability for an APSA claim.

FACTS AND PROCEDURAL BACKGROUND

¶2 In 2003, Maricopa County created a special health care district—now known as Valleywise—under A.R.S. § 48-5501.01 to acquire and operate Maricopa County owned hospitals and health care facilities. “A special health care district is a tax levying public improvement district

2 MARICOPA v. JACKSON Opinion of the Court

for all purposes of article XIII, § 7, Constitution of Arizona.” A.R.S. § 48- 5501.01(D). Tax levying public improvement districts are “political subdivisions of the state, and vested with all the rights, privileges and benefits, and entitled to the immunities and exemptions granted municipalities and political subdivisions.” Ariz. Const. art. 13, § 7. A special health care district may “[s]ue and be sued in all courts and places and in all actions and proceedings.” A.R.S. § 48-5541(2).

¶3 Jackson is the legal guardian of Matthew Heinreich. Heinreich has an intellectual disability and mental illnesses but lived independently. He managed his conditions with medications, specifically Clozapine and Benzodiazepines. In January 2022, he was admitted to Valleywise and treated by staff from Desert Medical Group (“DMG”) after exhibiting symptoms of an altered mental state.

¶4 In June 2022, Jackson filed a notice of claim against Valleywise and Maricopa County for injuries caused by “gross medical negligence while providing health care to Matthew Heinreich.” Specifically, she claimed that she informed Valleywise of Heinreich’s need to take Clozapine, but Valleywise failed to provide him with “any Clozapine for several days thus causing [Heinreich] to become progressively unresponsive and rigid and enter a state of malignant catatonia.” She contended that Valleywise “fell below medical standards of care by (1) failing to provide [Heinreich] proper medication management thereby causing him to suffer malignant catatonia and/or neuroleptic malignant syndrome and (2) failing to promptly recognize and properly treat malignant catatonia.”

¶5 In January 2023, Jackson sued Valleywise and DMG for medical negligence and negligent infliction of emotional distress. In April 2024, Jackson moved to file a first amended complaint, adding a claim that Valleywise and DMG violated APSA. The motion stated that the APSA claim “arises out of the same conduct set forth in the original Complaint.” In August 2024, Jackson filed the amended complaint, adding an APSA claim.

¶6 Valleywise moved to dismiss the APSA claim, arguing that it had no liability under APSA because, under Estate of Braden ex rel. Gabaldon v. State, 228 Ariz. 323 (2011), it did not qualify as a “person” or “enterprise” under A.R.S. § 46-455(B). Valleywise also argued that Jackson’s notice of claim did not contain facts sufficient to give notice of an APSA claim. See A.R.S. § 12-821.01(A). DMG also moved to dismiss, arguing that it was not subject to APSA. The court dismissed the APSA claim against DMG,

3 MARICOPA v. JACKSON Opinion of the Court

concluding that DMG was not subject to APSA, but denied Valleywise’s motion. It found that “Plaintiff sufficiently alleged claims under the APSA against Valleywise. Unlike Estate of Braden, Valleywise is alleged here to have directly participated in the abuse. Plaintiff alleges that Valleywise did not merely coordinate or supervise—it is directly liable for the negligent care.” Further, the court found the notice of claim complied with the notice of claim statute, A.R.S. § 12-821.01. Valleywise then filed this special action.

DISCUSSION

¶7 We review a ruling on a motion to dismiss de novo. See City of Mesa v. Ryan, 258 Ariz. 297, 299 ¶ 8 (2024); Shepherd v. Costco Wholesale Corp., 250 Ariz. 511, 513 ¶ 11 (2021) (dismissal under Arizona Rule of Civil Procedure 12(b)(6) reviewed de novo). “Dismissal is appropriate under Rule 12(b)(6) only if ‘as a matter of law [ ] plaintiffs would not be entitled to relief under any interpretation of the facts susceptible of proof.’” Coleman v. City of Mesa, 230 Ariz. 352, 356 ¶ 8 (2012) (quoting Fid. Sec. Life Ins. Co. v. State Dep’t of Ins., 191 Ariz. 222, 224 ¶ 4 (1998)). “On appeal from a motion to dismiss, this court ‘assume[s] the truth of [all] well-pled factual allegations and indulge[s] all reasonable inferences therefrom.’” Swift Transp. Co. of Ariz. v. Ariz. Dep’t of Revenue, 249 Ariz. 382, 383 ¶ 3 (App. 2020) (quoting Cullen v. Auto-Owners Ins. Co., 218 Ariz. 417, 419 ¶ 7 (2008)).
