OPINION
¶ 1 This appeal asks us to determine whether the medical payments coverage of an automobile insurance policy issued by Allstate Insurance Company covers accident-related health care expenses of its insured, Lisa Samsel, even though most of the expenses were covered by her health care services organization (HMO). Based on the following undisputed facts, we conclude that the policy covers those expenses.
¶ 2 Lisa sustained injuries in an automobile accident and was taken by ambulance to University Medical Center (UMC), where she received medical care and signed a “Conditions of Admission” form, agreeing “to pay all of [her UMC] charges as and when billed.” At the time, Lisa was enrolled in Partners Health Plan, an HMO governed by the provisions of A.R.S. §§ 20-1051 through 20-1077. Lisa was also an insured under her parents’ Allstate automobile policy. Although the policy included medical payments coverage, for which the parents paid an additional premium, Allstate paid only those hospital and medical charges that were not covered by Lisa’s HMO and denied coverage on the remaining charges billed to Lisa, asserting that because her HMO was obligated to pay them, Lisa had not “actually incurred” those charges, as required by the policy.
¶ 3 Lisa and her parents sued Allstate, alleging breach of contract, bad faith, and other claims. After both parties moved for summary judgment on the breach of contract claim, the trial court granted summary judgment in favor of Lisa and her parents and expressly entered final judgment pursuant to *482 Rule 54(b), Ariz.R.Civ.P., 16 A.R.S. 1 The trial court then denied Allstate’s motions for a new trial and discovery. This appeal followed.
¶ 4 “Our standard of review for a grant of summary judgment is
de novo
for both factual and legal determinations.”
Aranki v. RKP Inv., Inc.,
¶ 5 The trial court granted summary judgment based primarily on
Coconino County v. Fund Administrators Ass’n, Inc.,
¶ 6 Other courts have reached a similar conclusion. For example, in
Hermitage Health and Life Insurance Co. v. Cagle,
The general rule is that the insured will not be barred from recovery on a policy, providing for payment of hospital or medical services, etc., for which he has ‘incurred expense,’ or similar [policy] language, by mere reason of the availability of collateral means of discharging his liability therefor so as to have relieved him of the need to pay the charges personally.
See also Hollister v. Government Employees Ins. Co.,
¶ 7 But courts have reached a contrary conclusion when the medical services are provided without cost or free of charge. Illustrative is
United States v. Metropolitan Life Insurance Co.,
¶ 8 Allstate acknowledges Coconino’s holding and the principles enunciated above but contends § 20-1072 precludes their application in this case. The relevant sections of the statute provide:
A. Every written contract between a[n][HMOJ and a provider or hospital shall set forth that if the [HMO] fails to pay for covered health care services as set forth in the enrollee’s evidence of coverage or contract the enrollee is not liable to the provider or hospital for any amounts owed by the [HMO] and the provider or hospital shall not bill or otherwise attempt to collect from the enrollee the amount owed by the [HMO].
B. If the written contract between the contracting provider or hospital and the [HMO] fails to contain the required prohibition stated in subsection A, the enrollee is not liable to the contracting provider or hospital for any amounts owed by the [HMO].
C. No contracting provider or agent, trustee or assignee of the contracting provider or hospital may maintain an action at law against an enrollee to collect any amounts owed by the [HMO] for which the enrollee is not liable to the contracting provider under subsection A.
E. Nothing in this section prohibits an enrollee from seeking health care services from a contracting or noncontracting provider or hospital and accepting financial responsibility for these services.
¶ 9 Allstate claims subsections A, B, and C establish, as a matter of law, that Lisa is not hable for the UMC charges covered by her HMO and thus, unlike the student in
Coconino,
Lisa did not “actually incur” those charges. In response, Lisa argues that, notwithstanding subsections A through C, she could and did accept financial responsibility for the charges pursuant to subsection E when she signed UMC’s “Conditions of Admission” form. We review de novo the interpretation of a statute.
State Compensation Fund v. Superior Court,
¶ 10 Allstate asserts that, logically read, subsection E allows enrollees “to accept financial responsibility only for health care services that are
not covered
by their [HMO] plan.” Allstate cites no authority for this narrow reading, and we find it disregards the subsection’s express language. A cardinal principle of statutory construction requires us to interpret a statute, “whenever possible, so that no clause, sentence, or word is rendered superfluous, void, contradictory, or insignificant.”
Continental Bank v. Arizona Dep’t of Revenue,
¶ 11 Nor do we agree with Allstate that this interpretation makes “no sense” or renders subsections A through C “meaningless.” Although the legislature did not expressly state its intent or purpose with respect to § 20-1072 and its related statutes, 2 subsection E obviously encourages providers to furnish health care services when coverage or payment may be uncertain. It allows providers to obtain an enrollee’s acceptance of financial responsibility for the services and thus gives providers greater assurance that they will receive payment, regardless of whether the enrollee’s HMO covers the service, declines coverage, becomes insolvent, or *484 otherwise fails to make payment. By the same token, subsection E allows enrollees to obtain necessary health care services when a an HMO refuses coverage or coverage for some services may be questionable.
¶ 12 Allstate nonetheless argues that “to the extent [Lisa’s admission form] is construed as attempting to waive the protections of [subsections A through C], it is void and unenforceable,” citing
Landi v. Arkules, 172
Ariz. 126,
¶ 13 Allstate urges two additional grounds for not enforcing Lisa’s agreement to accept responsibility for her UMC charges: the agreement is without consideration, and it constitutes an unenforceable adhesion contract. Lisa responds that Allstate has no “standing” to raise these defenses. “Standing” is a judicially imposed requirement that parties possess an interest in the outcome to preclude advisory decisions.
See Citibank (Arizona) v. Miller & Schroeder Fin., Inc.,
¶ 14 “Privity is that connection or relationship which exists between two or more contracting parties.”
First Nat’l Bank of Windsor v. Gilbert Marshall & Co.,
¶ 15 But a non-party, such as Allstate, who qualifies as a third-party beneficiary, may be able to sue to enforce a contract. However, “[f]or a third party to maintain an action on a contract, the contract must have been entered into for the express benefit of the third party; the party cannot be merely an incidental beneficiary.”
Araiza v. U.S. West Bus. Resources, Inc.,
*485 ¶ 16 For the foregoing reasons, we hold that notwithstanding the provisions of subsections A through C of § 20-1072, subsection E of the statute authorized Lisa to accept financial responsibility for her UMC hospital and medical expenses, even though most of the expenses were covered by her HMO. When Lisa signed UMC’s “Conditions of Admission” form, she agreed to accept responsibility and, thus, liability for the expenses subject, of course, to any affirmative defenses she might have to that liability, such as failure of consideration, duress, waiver, or. payment. See Ariz.R.Civ.P. 8(e). Accordingly, Lisa “actually incurred” those expenses for coverage purposes under the medical payments provision of Allstate’s policy. 3 The trial court could, therefore, properly grant summary judgment to Lisa and her parents on them breach of contract claim, absent any genuine issues of material fact.-
¶ 17 Allstate attempted to raise such a factual issue in its motions for a new trial and discovery. Allstate argued that, in granting summary judgment, the trial court had improperly inferred that Lisa had made a knowing and informed waiver of the protections provided by subsections A through C of § 20-1072 when she signed the “Conditions of Admission” form. Allstate thus sought to depose Lisa and representatives of UMC and her HMO on the waiver issue. The trial court denied the motions, a decision we review for an abuse of discretion.
See Piper v. Bear Med. Sys., Inc.
¶ 18 We therefore affirm the trial court’s order granting summary judgment in favor of Lisa and her parents on the breach of contact claim. And, pursuant to them request under A.R.S. § 12-341.01, we will award Lisa and her parents attorney’s fees on appeal upon compliance with Rule 21(c), Ariz.R.Civ.App.P., 17B A.R.S.
