— This appeal had its inception when a group of State Farm Insurance Company (State Farm) policyholders commenced a class action against State Farm claiming that the insurance company breached fiduciary and contractual obligations, acted in bad faith, and violated the Consumer Protection Act (chapter 19.86 RCW). The trial court granted State Farm’s motion for summary judgment and dismissed the plaintiffs’ causes of action. The Court of Appeals reversed the trial court, concluding that there were material issues of fact which precluded summary judgment in favor of State Farm. State Farm obtained review here, claiming that the Court of Appeals (1) erred in its formulation of the fiduciary duty owed by State Farm to its insureds, and (2) neglected to analyze the plaintiffs’ claims in the context of the entire class. We affirm the Court of Appeals and remand for trial.
I. FACTS
As noted above, the underlying action is a class-action lawsuit. Consequently, the events surrounding each class member’s injury and subsequent dealings with State Farm vary to some extent. However, because the facts relating to one member of the class of plaintiffs, Tina Van Noy, are essentially representative of the entire class, we chronicle her circumstances.
*787On October 14,1993, Van Noy was injured in an automobile accident. Soon thereafter, she began a course of treatment that had been prescribed to her by her chiropractor. At the time of the accident, Van Noy was insured by State Farm. Her policy included personal injury protection (PIP), which is essentially no-fault coverage for medical expenses arising from bodily injuries sustained in an automobile accident. The PIP benefits that State Farm provided to Van Noy were described in the policy as follows:
What we Pay
We will pay for bodily injury to an insured caused by accident resulting from the maintenance or use of a motor vehicle as a motor vehicle:
1. Medical Expenses. These are reasonable expenses incurred within three years of the date of the accident. These expenses are for necessary:
a. medical, surgical, X-ray, dental, ambulance, hospital, professional nursing and rehabilitative services [.]
Clerk’s Papers (CP) at 791. The “Settlement of Loss” portion of the policy stated that:
Payments will be made on a monthly basis within 30 days after we have proof of the amount due.
CP at 619. The same section further provided:
The amount due under this coverage shall be decided by agreement. If the insured and we cannot agree, it will be decided by arbitration upon mutual written consent.
CP at 619.
Approximately three weeks after the accident, Van Noy received a letter from the State Farm “First Party Benefits Expediter.” CP at 793. The letter requested that Van Noy complete an enclosed application for medical benefits and also stated that:
Your insurance policy provides for payment of medical expenses that are reasonable and necessary. To assist us in *788determining this, we may obtain a second medical opinion. We may also have the treatment reviewed by other medical professionals. Your policy provides you must notify us as soon as reasonably possible after your treatment begins.
CP at 794. Van Noy complied with State Farm’s request and filled out the medical benefits application. She then returned it to State Farm. This was followed by the submission to State Farm of billings that Van Noy had received from her health care providers.
For several months after the application and billings were sent to State Farm, Van Noy had no contact with the company. Finally, on March 28, 1994, nearly five months after Van Noy first began receiving treatment for her injuries, she received a missive from State Farm that stated, in relevant part, that:
Our contract of insurance with you requires that we pay only charges that are reasonable, necessary, and accident related. For that reason, we will be submitting the chiropractic and massage billings to an independent chiropractic consultant for evaluation. We will be guided by their recommendations and will pay only those charges which are deemed reasonable and necessary.
CP at 796.
Approximately one month later, Van Noy’s attorney received another letter from State Farm. This letter indicated that State Farm’s “peer review” determined that only a portion of Van Noy’s claims would be paid. CP at 798. The letter also informed Van Noy’s attorney that the “peer review group” was in the midst of evaluating the other billings submitted by Van Noy and that State Farm “will advise you of the outcome.” CP at 798. As a consequence of State Farm’s action, Van Noy remained personally liable for the unpaid portion of the expenses for her treatment.
II. PROCEEDINGS
Shortly thereafter, Van Noy and two other State Farm policyholders, Patricia Faye Dinnis and Elaine Ebersole, *789initiated a class-action lawsuit against State Farm. In their complaint they alleged that State Farm: (1) breached its fiduciary duty and contractual obligations, (2) engaged in bad faith handling of claims, and (3) violated the Washington Consumer Protection Act (CPA). Fundamentally, the plaintiffs complained that State Farm ignored the language in its policies that provided that payments be made on a monthly basis and, instead, “stockpiles” the bills for months before finally deciding whether to honor claims for medical expenses. Answer to Pet. for Review at 1. The plaintiffs sought damages for all health care provider expenses that State Farm disallowed more than 30 days after receipt of the PIP claims. All of their causes of action were based on what they claimed was “State Farm’s practice of retroactive denial of coverage, effective months prior to when the notice [was] given.” CP at 30. Pursuant to CR 23, the plaintiffs moved for class certification. Over State Farm’s objections, the trial court granted their motion and certified a statewide class of State Farm policyholders whose policies contained PIP coverage.
The class moved for partial summary judgment on the issues of State Farm’s duty and breach of that duty. State Farm responded with its own summary judgment motion, asserting that all of the claims against it should be dismissed. The trial court denied the class’s motion but granted State Farm’s and dismissed the lawsuit entirely.
The class appealed to Division One of the Court of Appeals. That court reversed the grant of summary judgment in favor of State Farm, and remanded for trial, concluding that there were issues of material fact with respect to each cause of action brought by the plaintiffs. See Van Noy v. State Farm Mut. Auto. Ins. Co., 98 Wn. App. 487, 983 P.2d 1129 (1999). We, thereafter, granted State Farm’s petition for review.
III. DISCUSSION
State Farm’s petition raises two issues for our consider*790ation. It first contends that the Court of Appeals erroneously formulated the applicable fiduciary duty that State Farm owes to its first-party insureds. State Farm’s second claim of error is that the Court of Appeals “erred in its treatment of plaintiffs’ breach of contract claim.” Pet. for Review at 14.1 The class responds that the appellate court correctly formulated the applicable fiduciary duty and did not err in concluding that there was a factual question as to whether State Farm breached its contract with Van Noy, Dinnis, Ebersole and the other members of the class.
Summary judgment orders are reviewed de novo by this court. Hayden v. Mat. ofEnumclaw Ins. Co., 141 Wn.2d 55, 1 P.3d 1167 (2000). In doing so we observe the well-known principle that summary judgment is appropriate “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” CR 56(c). Such a motion will be granted, after considering the evidence in the light most favorable to the nonmoving party, only if reasonable persons could reach but one conclusion. Reynolds v. Hicks, 134 Wn.2d 491, 495, 951 P.2d 761 (1998).
A. State Farm’s Fiduciary Duty
State Farm asserts that the Court of Appeals erred in two respects in its analysis of the fiduciary duty it owed to the plaintiff class. There are two components to State Farm’s argument. First, it claims that the appellate court’s opinion could be erroneously interpreted as imposing a duty on insurance companies to “ ‘disclose all facts that would aid *791its insureds in protecting their interests ....’” Pet. for Review at 9. It also asserts that the Court of Appeals incorrectly imposed a “novel duty” on State Farm when the court stated that “ £[a]n insurer has an enhanced fiduciary obligation ....’” Pet. for Review at 11. In support of its argument, State Farm points to the following portion from the Court of Appeals opinion:
A fiduciary or quasi-fiduciary relationship exists between an insurer and its insured. An insurer has an enhanced fiduciary obligation that rises to a level higher than that of mere honesty and lawfulness of purpose. It requires an insurer to deal fairly with an insured, giving equal consideration in all matters to the insured’s interests as well as its own.
The representatives argue that State Farm owed and violated three overlapping fiduciary duties to its insureds: (1) the duty to disclose all facts that would aid its insureds in protecting their interests; (2) the duty of equal consideration; and (3) the duty not to mislead its insureds.
Whether or not breach of any of these duties is ultimately supported, at a minimum there is a factual question in this case whether State Farm fully, timely, or adequately disclosed the possibility of the retroactive denial of medical claims.
Van Noy, 98 Wn. App. at 492 (footnotes omitted).
State Farm takes exception to this excerpt from the Court of Appeals decision to the extent it appears to impose a duty on State Farm to “ ‘disclose all facts that would aid its insureds in protecting their interests ....’” Pet. for Review at 9. It contends that an insurer does not owe such a duty to its insured. Such a duty, it argues, exists only in legal relationships that are deemed “true fiduciary relationships” such as the relationship between a trustee and a beneficiary. Id. (citing Allard v. Pac. Nat’l Bank, 99 Wn.2d 394, 663 P.2d 104 (1983)).
State Farm is correct in observing that the phrase “duty to disclose all facts that would aid its insureds” has its roots in a decision of this court that dealt with a true fiduciary relationship, i.e., the relationship between a trustee and beneficiary. In Esmieu v. Schrag, 88 Wn.2d 490, 498, 563 *792P.2d 203 (1977), we observed that a trustee’s fiduciary “duty includes the responsibility to inform the beneficiaries fully of all facts which would aid them in protecting their interests.” Id. (emphasis added). After our decision in Esmieu, we noted in another case that the fiduciary duty we discussed in Esmieu was that of a “true fiduciary” and further observed that “something less than a true fiduciary relationship exists” in the insurance context. Safeco Ins. Co. of Am. v. Butler, 118 Wn.2d 383, 389, 823 P.2d 499 (1992). Thus, it appears that the phrase State Farm assails, which is based on our decision in Esmieu, has no application in an insurance context.
We are not troubled, however, by the fact that the Court of Appeals made reference to the language in Esmieu applicable to a “true fiduciary.” That is so because the Court of Appeals merely made reference to the “duty to disclose all facts that would aid its insureds” in setting forth the argument advanced by the class representatives. It did not, in our judgment, indicate that there was a factual question about whether this duty was breached. Rather, it concluded that there was a factual question about “whether State Farm fully, timely, or adequately disclosed the possibility of the retroactive denial of medical claims.” In short, the Court of Appeals did not hold, nor did it suggest, that State Farm was a “true fiduciary.” To the contrary, the opinion explicitly states that a “quasi-fiduciary relationship” exists between State Farm and the plaintiff class. Van Noy, 98 Wn. App. at 492.
State Farm also contends that the Court of Appeals erred by imposing a “novel fiduciary duty” on State Farm by stating that “ ‘[a]n insurer has an enhanced fiduciary obligation ....’” Pet. for Review at 11. State Farm suggests that an insurance company has an “ ‘enhanced fiduciary obligation’ ” only when it is “defending an insured under a third-party liability policy, and under a reservation of rights.” Id. at 11-12. Because in this case State Farm is dealing with its insured, it argues, it has no “enhanced fiduciary obligation.” Id. at 11.
*793The lower court’s discussion of fiduciary duty cannot, in our view, be read as wrongly stating the fiduciary duty that State Farm owed to the plaintiff class. As we have noted, the Court of Appeals correctly observed that there is a “quasi-fiduciary relationship [that] exists between an insurer and its insured.” Van Noy, 98 Wn. App. at 492. The court was also correct when it followed the reference to an insurance company’s “enhanced fiduciary obligation” with the statement that an insurer must “deal fairly with an insured, giving equal consideration in all matters to the insured’s interests as well as its own.” Van Noy, 98 Wn. App. at 492. The latter statement from the Court of Appeals’ opinion regarding the obligations of an insurer is unassailable because it is essentially a verbatim statement of the fiduciary duty that this court has imposed upon insurance companies in both first-party and third-party contexts.2 See Coventry Assocs. v. Am. States Ins. Co., 136 Wn.2d 269, 280, 961 P.2d 933 (1998); McGreevy v. Or. Mut. Ins. Co., 128 Wn.2d 26, 36-37, 904 P.2d 731 (1995) (citing Tank v. State Farm Fire & Cas. Co., 105 Wn.2d 381, 385-86, 715 P.2d 1133 (1986)). It is not at all surprising to us, therefore, that *794the Court of Appeals cites to both McGreevy and Tank to support its discussion of the insurers’ fiduciary duty.
The only arguable problem with the Court of Appeals’ formulation of the fiduciary duty is its use of the word “enhanced” to modify the words “fiduciary obligation.” See Van Noy, 98 Wn. App. at 492. The use of that word is not, however, problematic because it is apparent that the Court of Appeals used it to emphasize the fact that an insurance company has an elevated good faith obligation “that rises to a level higher than that of mere honesty and lawfulness of purpose.” Van Noy, 98 Wn. App. at 492. We are satisfied that the reference to “enhanced fiduciary obligation” was not made to impose a novel fiduciary duty on State Farm. A comparison of this court’s discussion of an insurance company’s fiduciary obligation in Tank and the Court of Appeals statement in Van Noy leads us to this conclusion. In Tank, we noted that:
an insurance company’s duty of good faith rises to an even higher level than that of honesty and lawfulness of purpose toward its policyholders: an insurer must deal fairly with an insured, giving equal consideration in all matters to the insured’s interests.
Tank, 105 Wn.2d at 386. As the excerpt from Tank illustrates, an insurance company has an elevated or “enhanced” duty of good faith which requires it to “deal fairly,” giving “equal consideration” to its insureds. In sum, we believe that it is this duty of fair dealing and equal consideration that the Court of Appeals was referring to when it made the statement to which State Farm takes exception.
We hold that the Court of Appeals did not err in its formulation of the applicable fiduciary duty that an insurer owes to its insured. That duty, as has been described by the courts of this state on several occasions, is a duty to exercise a high standard of good faith which obligates it to deal fairly and give “equal consideration” in all matters to the insured’s interests. The Court of Appeals did not stray from that definition and, therefore, there was no error in its *795formulation of the applicable fiduciary duty that State Farm owes to the plaintiff class.
B. Plaintiffs5 Breach of Contract Claim
State Farm also contends that the Court of Appeals neglected to analyze the plaintiffs’ breach of contract claim in the class context. More specifically, it suggests that the court erred in distinguishing the Court of Appeals case of Reichl v. State Farm Mutual Automobile Insurance Co., 75 Wn. App. 452, 880 P.2d 558 (1994), in its analysis of plaintiffs’ contract claims.
The plaintiffs’ breach of contract claim is based on the language in the insurance policy that states “[p]ayments will be made on a monthly basis within 30 days after we have proof of the amount due.” The class contends that this language obligated State Farm to pay or deny claims within 30 days of receipt of medical bills or, at minimum, provide “sufficient disclosure of the possibility of retroactive denial.” Answer to Pet. for Review at 15. State Farm argues that the Court of Appeals failed to follow the Reichl opinion, suggesting that it is a case where the court was “confronted with precisely the same policy language” we have here. Pet. for Review at 14. According to State Farm, the Court of Appeals, Division Two, held in Reichl that “ ‘proof of the amount due’ ” is not equivalent with “ ‘submission of medical bills.’ ” Id. It argues, therefore, that it was not in breach of the insurance contract when it failed to pay the claims within 30 days after it received medical bills from its insured.
We find ourselves in agreement with the Court of Appeals that Reichl is distinguishable from the present case. In that case, the plaintiff sought damages from her insurance company for delay in payment of her medical bills. The Court of Appeals concluded there that delay damages were not justified under the evidence because the plaintiff had failed to timely provide additional proof or information sought by the insurer before fully settling her claims *796against the tortfeasor. In other words, because the plaintiff in Reichl was partially at fault for any delay in processing the claims, damages were not available to her.
Here, unlike the situation in Reichl, the issue of who is responsible for the delay is not material to the plaintiffs’ breach of contract claim. The plaintiffs claim that State Farm breached the contractual agreement because it failed to “provide □ sufficient disclosure of possibility of the retroactive denial.” Answer to Pet. for Review at 15. The contractual issue, therefore, revolves around the reasonableness of State Farm’s action in handling the claims that were presented to it. As the Court of Appeals correctly observed, that issue should be resolved by a trier of fact.
IV. CONCLUSION
In conclusion, we are satisfied that the Court of Appeals properly defined the scope of State Farm’s fiduciary duty in this case. Furthermore, we do not believe that the Court of Appeals erred in its analysis of the plaintiffs’ breach of contract claim. We, therefore, affirm the Court of Appeals determination that the decision of the trial court granting summary judgment to State Farm should be reversed.
Smith, Sanders, Ireland, and Bridge, JJ., and Guy, J. Pro Tern., concur.
State Farm also asserts in its petition for review that the plaintiffs failed to present “class-wide evidence” of reliance and breach in their tort and CPA claims. Pet. for Review at 15, 19. These arguments essentially attack the trial court’s decision to certify this case as a class action lawsuit. Because State Farm could have raised these certification issues at the Court of Appeals, we do not address these issues. See RAP 5.1(d); RAP 2.4(a). We also decline to discuss issues that State Farm has raised in its supplemental brief because these issues were not previously raised in State Farm’s petition for review. See RAP 13.7(b).
We note that Justice Talmadge asserts, in his concurring opinion, that an insurer does not owe a fiduciary duty to its insureds in the first-party insurance context, but rather, owes only a duty of “good faith.” We are doubtful that there is any real difference between a “fiduciary” duty and a duty of “good faith” in the insurance context. We say that because we have long held that the duty of the insurer to act in good faith toward the insured is the same as the fiduciary relationship that the insurer has to the insured. See Tank v. State Farm Fire & Cas. Co., 105 Wn.2d 381, 385, 715 P.2d 1133 (1986) (“The duty to act in good faith or liability for acting in bad faith generally refers to the same obligation . . . the fiduciary relationship existing between the insurer and insured.”).
Even assuming, however, that there is a difference between a “fiduciary” duty and a duty of “good faith” in the insurance context, we disagree with the notion that an insurer has only a duty of “good faith,” and not a “fiduciary” duty, to its insureds in the first-party insurance context. We note in this regard that we have stated: “[T]he fiduciary relationship existing between insurer and insured .. . exists not only as a result of the contract between insurer and insured, but because of the high stakes involved for both parties to an insurance contract and the elevated level of trust underlying insureds’ dependence on their insurers.” Tank, 105 Wn.2d at 385. This dependence and heightened level of trust exists not only where the insurer’s and the insured’s interests are aligned, as in the third-party context, but also, and perhaps even more so, in the first-party context, where the insurer’s interests might be opposed to the insured’s and the insured is particularly vulnerable and dependent on the insurer’s honesty and good faith.
