ORDER
Patrick J. Schütz, United States District Judge
Two health-care providers — Dr. Louis Peterson and Riverview Health Institute (“Riverview”) — bring these actions on behalf of certain of their patients against UnitedHealth Group Inc. and various of its affiliates (collectively “United”). United acts as the administrator for numerous health plans governed by the Employee Retirement Income Security Act (“ERISA”), 29 U.S.C. 1001 et seq. According to plaintiffs, United has wrongfully failed to pay them and other providers who have treated patients enrolled in United-administered plans. Instead of paying the providers what they are owed, plaintiffs allege, United withholds some or all of their payments in order to offset overpay-ments that United claims to have made to the providers in connection with their treatment of different patients enrolled in different plans. Plaintiffs allege that this practice — known as “cross-plan offsetting” — violates ERISA and the terms of the plans.
This matter is before the Court on the parties’ cross-motions for summary judgment on the issue of whether the relevant plans authorize cross-plan offsetting. For the reasons explained below, the Court holds that they do not. But because this order “involves a controlling question of law as to which there is substantial ground for difference of opinion” and because “an immediate appeal from the order may materially advance the ultimate termination of the litigation,” the Court certifies this order for immediate appeal pursuant to 28 U.S.C. § 1292(b).
I. BACKGROUND

A. Cross-Plan Offsetting

United is one of the largest health insurers in the world. It both administers and insures health-insurance plans. Some of the plans that United administers are fully insured, meaning that United uses its own funds to pay claims. Other plans that United administers are self-insured, meaning that United uses the funds of the plan sponsor to pay claims. Bishop-Heroux Dep. 26-27. United’s fully insured business accounts for 22 percent of all claim payments; the remainder come from self-insured plans. Bishop-Heroux Dep. 55-56.
Administering health-insurance plans is a complex business, and United inevitably makes mistakes. One type of mistake is to pay a provider more than the provider is owed under the patient’s health-insurance *837plan. This litigation challenges a particular technique that United uses to recover such overpayments — a technique known as “cross-plan offsetting.” The technique takes a little explaining:
Suppose that a patient named Andy is insured under a health plan administered by United. Andy sees Dr. Peterson for treatment of a sore neck. Dr. Peterson submits his bill to United. United pays $350 to Dr. Peterson. Later, however, United discovers that it should have paid only $200 to Dr. Peterson. United contacts Dr. Peterson, brings the overpayment to his attention, and asks him to return $150.
If Dr. Peterson agrees that he was overpaid and returns the $150, the problem is solved. But if Dr. Peterson does not agree that he was overpaid and refuses to return the money, United has limited options for getting back its $150. In theory, United could initiate administrative or legal proceedings against Dr. Peterson. As a practical matter, however, United is unlikely to do so, as United would spend far more than $150 in pursuing the $150 overpayment.
Another option might be to engage' in same-plan offsetting. Under this approach, United would wait until Andy or anyone else covered by Andy’s health plan is treated by Dr. Peterson. When Dr. Peterson submits a bill to United on behalf of that patient, United would deduct $150 from the payment that it would otherwise make to Dr. Peterson. From United’s perspective, however, same-plan offsetting presents a big problem: Dr. Peterson may never again treat Andy or someone who is insured under Andy’s plan. Dr. Peterson practices in New York City, a giant metropolitan area. Andy may work for a small company in a distant suburb, and he may be insured under a company-sponsored plan that covers only Andy and 20 other employees. The chances may be slim that Dr. Peterson will ever again treat someone who is insured under Andy’s plan. And thus, United may never have the opportunity to use same-plan offsetting to recoup its $150 overpayment from Dr. Peterson.
To get around this problem, United adopted the practice of cross-plan offsetting. Under this approach, United merely has to wait until anyone covered by any of the thousands of plans that it administers sees Dr. Peterson. Suppose, for example, that two weeks after treating Andy, Dr. Peterson treats Betsy, who is injured while on vacation in New York City. Suppose further that Betsy is insured under a plan that is administered by United and that covers Betsy and 50 of her co-employees (all of whom live in San Diego). When Dr. Peterson submits a bill to United on behalf of Betsy, United would deduct $150 from the payment that Betsy’s plan would otherwise make to Dr. Peterson and thereby recoup the overpayment that Andy’s plan made to Dr. Peterson in connection with his treatment of Andy. It is this practice of cross-plan offsetting that Dr. Peterson and Riverview challenge in these lawsuits.
In their briefs, the parties refer to the allegedly overpaid claims (such as Dr. Peterson’s claim for treating Andy) as the “A claims,” and the plans that made these overpayments (such as the plan that covered Andy) as the “A Plans” or “Plan As.” The parties refer to the later claims that United purportedly paid through debt cancellation (such as Dr. Peterson’s claim for treating Betsy) as the “B claims,” and the corresponding plans (such as the plan that covered Betsy) as the “B Plans” or “Plan Bs.”1
*838Dr. Peterson and Riverview are both out-of-network providers who provided services to an “Andy” — that is, to a patient who was insured under a Plan A administered by United, Both providers submitted claims to United. Both received payment for those claims from the Plan A. Both were later informed by United that they had been paid too much. Both disputed that they had been paid too much, and both refused to return the alleged overpayment. With respect to both, United responded by recouping the disputed overpayment through cross-plan offsetting. In other words, when United learned that Dr. Peterson or Riverview had submitted a subsequent claim regarding a “Betsy”— that is, a different patient who was insured under a different United-administered plan (a Plan B) — United did not pay for those claims by transferring money to Dr. Peterson or Riverview. Instead, United purported to pay for those claims by cancelling debt that Dr. Peterson or Riverview allegedly owed to the Plan A.
Cross-plan,offsetting advantages United and disadvantages providers. When United and a provider dispute whether a claim was overpaid, cross-plan offsetting allows United to act as judge, jury, and executioner. United treats the provider as being in debt to Plan A — -no matter how strongly the provider denies being in debt to Plan A — and United collects that disputed debt by offsetting money that Plan B owes to the provider. In theory, the provider could initiate administrative or legal proceedings against United to recover the offset. As a practical matter, however, the provider is unlikely to do so, as the provider would spend far more than, say, $150 in pursuing a $150 offset. In short, without offsetting, the onus would be on United to initiate proceedings and prove that the provider was overpaid by Plan A. With offsetting, the onus shifts to the provider to initiate proceedings and prove that it was underpaid by Plan B.
As much as providers such as Dr. Peterson and Riverview may dislike offsetting, they do not have standing to bring these actions in their own right. That is because health-insurance plans are contracts, between United, on the one hand, and patients or in-network providers, on the other hand. Dr. Peterson and Riverview are out-of-network providers. Moreover, United has fiduciary obligations under ERISA to the patients, not to providers. For that reason, Dr. Peterson and Riverview have brought these actions as assignees or authorized representatives of their patients,2 and these actions focus on whether, by engaging in cross-plan offsetting, United has violated any legal duties to its insureds,
Speaking very broadly, plaintiffs make at least two contentions in these lawsuits. First, they argue that nothing in any of the relevant plans authorizes United to engage in cross-plan offsetting. That contention is the subject of the parties’ cross-*839motions for summary judgment and will be addressed at length in this order. Second, plaintiffs argue that, in engaging -in cross-plan offsetting, United is violating ERISA by -furthering its own interests at the expense of its insureds. In particular, when a “Betsy” (that is, someone insured under a Plan B) is treated by her doctor, she is legally responsible for paying her doctor’s bill. When United pays her doctor not with cash, but instead by cancelling a purported debt that the doctor denies owing, Betsy’s doctor may very well assert that he has not been paid for treating Betsy and demand that Betsy pay the full amount of his bill. Betsy would not be placed at such financial risk if United — which, as administrator of Plan B, owes a fiduciary duty to Betsy — -would use Plan B assets to pay Betsy’s doctor. Instead, United uses Plan B assets to help Plan A recover a disputed debt.

B. Development and Implementation of the Cross-Plan Offset System

United implemented its system of cross-plan offsetting in March 2007 as part of a wider overhaul of its payment system.3 Jacob Decl., Mar. 28, 2016 [hereinafter “First Jacob Decl.”] Ex. D. United did not implement cross-plan offsetting in response to a request from a plan sponsor or insured; instead, United came up with this system on its own. Burch Dep. 65-70, 177.
One benefit to United of implementing cross-plan offsetting has already been explained: When United and a provider dispute whether the. provider has been overpaid, United is able to act unilaterally to recoup the alleged overpayment and thereby place the burden on the provider to initiate proceedings and prove that it was not overpaid (something most- providers will not bother to do with respect to most disputed overpayments). Another benefit to United is not- as obvious: Many of the Plan As — that is, the plans that make the overpayments — are fully insured; in other words, the money that United mistakenly pays to a provider comes out of United’s pockets. Many of the Plan Bs — that is, the plans that send money .to the Plan As to reimburse them for the overpayments— are self insured; in other words, the money that reimburses United for its alleged overpayment comes out of the plan sponsors’ pockets. Several internal United documents emphasize this point and gush about how cross-plan offsetting will allow United to take money for itself out of the pockets of the' sponsors of self-insured plans. See Meyer Decl. Ex. A at 13735 (September 2004 presentation stating, in bold text, that the new system “[ajllows recovery of fully insured overpayments on self funded claim payments!”); id. Ex. H at 13910 (August 2004 presentation stating that “[grossing policies for bulk recovery helps recover FI [fully insured] dollars faster”); id. Ex. I at 13757 (callout on a 2005 chart of figures highlighting a “[fjully insured o/p recovery on a [self insured] payment!”).
Before implementing cross-plan offsetting, United sent a letter to existing clients4 describing the new system and how it would work. First Jacob Decl. Ex. D. The letter described the new system as follows:
*840Under our existing process, a claim overpayment for a self insured plan could only be recovered when both the overpayment and the claim payment involved the same self insured plan. Thus, a self insured plan that had a claim overpayment with a particular provider would have to wait until its participants incurred additional claims with that provider before the overpayment could be deducted. Under the new process, we will, in most instances, be able to recover claim overpayments made to a provider by reducing future claim payments to that provider, regardless of whether those future claim payments involve your plan, another self insured plan or a fully insured plan;
First Jacob Decl. Ex. D at 2605. In other words, United emphasized the potential benefits of cross-plan offsetting to the self-insured plans, but called no attention to the potential benefits of cross-plan offsetting to United itself.
United’s system for cross-plan offsetting includes rules for prioritizing recoveries. This is necessary because United might allege that multiple overpayments were made to a single provider. So, for example, United may allege that self-insured Plan A1 overpaid Dr. Peterson by $100 on May 1, and that fully insured Plan A2 overpaid Dr. Peterson by $125 on June 1, and that self-insured Plan A3 overpaid Dr. Peterson by $75 on July 1. When Dr. Peterson submits a claim to self-insured Plan B1 on August 1, and United decides that Plan B1 owes Dr. Peterson $200 in connection with that claim, and United further decides to use that $200 to recoup some of the over-payments previously made to Dr. Peterson, to which plan should United transfer Plan Bl’s money? Plan Al? Plan A2? Plan A3?
Under United’s system for cross-plan offsetting, fully insured plans are first in line to recover their overpayments from fully insured claim payments. Only after fully insured overpayments have been satisfied may self-insured plans recover from fully insured claim payments. Likewise, self-insured plans are first in line to recover from self-insured claim payments, after which fully insured plans may recover. Id. at 2606. The 2007 client letter explained this system and provided several illustrative examples. Id. at 2606-08.
In this litigation, every Plan A— that is, every plan that made overpay-ments — was fully insured. Meyer Decl. Exs. C, D. Conversely, the majority of the Plan Bs — that is, the majority of plans from which the overpayments were recovered — were self-insured. Meyer Decl. Ex. F; ECF No. 74 ¶ 5. In other words, every one of the cross-plan offsets at issue in this litigation put money in United’s pocket, and most of that money came out of the pockets of the sponsors of self-insured plans.5
*841When United implemented this system in 2007, it gave existing clients about two weeks to decide whether to opt out. First Jacob Decl. Ex. D at 2605 (exemplar letter giving clients until February 22, 2007 to opt out); id. Ex. A at 3859 (clients were given advance notice of letters by February 7 and letters were mailed on February 9). New clients do not have that option; they must participate in cross-plan offsetting or find a different claims administrator. Burch Dep. 282-83.
The parties dispute how much information about cross-plan offsetting United provides to its new clients and whether any of that information is in writing. As with several other issues, the record on this issue is somewhat murky. It appears, however, that disclosures concerning United’s system of cross-plan offsetting are mostly or entirely handled by United’s banking team during what appear to be fairly technical explanations of the banking; account-setup, and account-funding processes. Bishop-Heroux Dep. 192-94, 226-27; Bishop-Heroux Decl. ¶¶ 6-7; Second Jacob Decl. Ex. X. It also appears that such disclosures mostly occur orally and on a somewhat ad hoc basis, Burch Dep. 282, although United has identified one written document that explicitly mentions cross-plan offsetting — a document that United has apparently given to new clients since 2010. Bishop-Heroux Decl. 11 6; Second Jacob Deck Ex. X. The document does not provide nearly as much detail about cross-plan offsetting as the 2007 letter, however — and, like the 2007 letter, the document says nothing about the fact or extent of United’s conflict of interest. Second Jacob Decl. Ex. X at 3816. United says that it provides these oral and written disclosures to its clients’“benefits and finance and treasury folks,” Bishop-Heroux Dep. 227, but it is not clear whether those individuals have authority to make plan-wide fiduciary decisions, nor is it clear whether these disclosures are made before or after a plan sponsor decides to become a United client.

C. Plan B Language

As noted, the issue presently before the Court is whether the Plan Bs that are at issue in this litigation authorize United to engage in cross-plan offsetting. United argues that they do. Dr. Peterson and River-view argue that they do not.
There are 46 Plan Bs that are at issue in this litigation. All of those Plan Bs grant United the authority to interpret plan terms. ECF No. 120 Ex. B at 2-7. Almost all of those Plan Bs — specifically, 40 of 46 — also contain provisions that specifically address overpayments and recoveries. ECF No. 120 Ex. A. The parties have grouped these provisions into 16 different types; some plans have more than one type. Id. Having studied the parties’ charts, the Court has identified 17 different combinations of overpayment and recovery provisions that appear in the various plans.6
Every one of the overpayment and recovery provisions is triggered only when the plan itself makes an overpayment. ECF No. 120 Ex. B at 8-25. In other words, each Plan B authorizes the recovery of overpayments made by the Plan B. None of the overpayment or recovery provisions contain any language allowing other plans to recover their overpayments from the plan.7 In other words, not one *842Plan B authorizes recovery of an overpayment made by a Plan A
Of the 40 plans containing overpayment and recovery provisions, all except' four explicitly mention offsetting. EOF No. 120 Ex. B at 19, 21, 24-25 (N, P, S, and T provisions do not mention offsets). In every offset provision save one (provision G, which appears in only two plans), the authority of the administrator to offset is described in terms that make it clear that offsets are taken from other benefits payable under that plan or from other benefits or compensation paid by the plan's sponsor. Provision G contains similar language, stating:
If the Covered Person, or any other person or organization that was paid, does not promptly refund the full amount, we may reduce the amount of any future Benefits for the Covered Person that are payable under the Policy.
ECF No. 120 Ex. B at 11 (emphasis added). But provision G also includes somewhat broader language stating that, if a provider fails to respond to a notice of overpayment, the overpayment may be recovered “from other payments we owe the provider ....” Id.
In sum, 36 of the 46 Plan Bs that are at issue in this litigation specifically address offsetting; all of those plans explicitly authorize same-plan offsetting; and not one of those plans explicitly authorizes cross-plan offsetting.
Ii: ANALYSIS

A Standard of Review

Summary judgment is warranted “if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). A dispute over a fact is “material” only if its resolution might affect the outcome of the suit under the governing substantive law. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). A dispute over a fact is “genuine” only if “the evidence is such that a reasonable jury could return a verdict for the nonmoving party.” Id, “The evidence of the non-movant is to be believed, and all justifiable inferences are to be drawn in his favor.” Id. at 255, 106 S.Ct. 2505.

B. Authorization for Cross-Plan Offsetting

As noted, all of the Plan Bs grant United discretionary authority to interpret plan terms, United’s interpretation is therefore reviewed for abuse of discretion. King v. Hartford Life & Accident Ins. Co., 414 F.3d 994, 998-99 (8th Cir. 2005) (en banc).
United interprets the Plan Bs to authorize cross-plan offsetting,. Ultimately, the question for this Court is whether that interpretation is reasonable. Id. at 999. In making this determination, the Court must consider the factors identified in Finley v. Special Agents Mutual Benefit Association, 957 F.2d 617 (8th Cir. 1992), which include: (1) whether the interpretation is consistent with the goals of- the plan; (2) whether the interpretation renders any language in the plan meaningless or internally inconsistent; (3) whether the interpretation conflicts with the substantive or procedural requirements of ERISA; (4) whether the administrator has interpreted the relevant plan language consistently; and (5) whether the interpretation is contrary to the clear language of the plan. Id. at 621.
It should be noted that, in looking carefully at the language of the plans and considering the Finley factors, the Court is doing something that' United itself did not do before implementing cross-plan off*843setting. There is no evidence in the record that,.prior to implementing cross-plan offsetting, United examined the language of any plan or even considered whether the practice was authorized. Cf. King, 414 F.3d at 1001-04 (discussing the administrator’s consideration of plan language during the elaims-administration process). Instead, United simply plunged ahead. Only after getting sued did United hunt through the plans for any language that might provide a post hoc justification for its conduct. United’s hunt was not terribly successful. United admits that it was not able to find a single provision of a single plan that explicitly authorizes cross-plan offsetting. ECF No. 124 at 25 (“To be sure, none of the United Plans explicitly address cross-plan offsetting”). United is therefore left arguing that it has implicit authority to engage in cross-plan offsetting under common, generic provisions that require the administrator to' pay benefits and that grant the administrator discretion to interpret and administer the plans.8
United argues — and the Court does not doubt — that a plan need not spell out every possible action that a claims administrator may take on its behalf. United admits, however, that the discretion of a claims administrator is not unlimited. In determining what authority a plan gives to an administrator, the plan must be read in light of trust law and the fiduciary duties imposed by ERISA. Admin. Comm. of Wal-Mart Stores, Inc. Assocs.’ Health & Welfare Plan v. Gamboa, 479 F.3d 538, 542 (8th Cir. 2007); Finley, 957 F.2d at 621. These fiduciary duties are among “ ‘the highest known to the law.’ ” Braden v. Wal-Mart Stores, Inc., 588 F.3d 585, 598 (8th Cir. 2009) (quoting Donovan v. Bierwirth, 680 F.2d 263, 272 n.8 (2d Cir. 1982)). ERISA requires plan fiduciaries to discharge their duties “solely in the interest of the participants and beneficiaries” and for the “exclusive purpose” of providing benefits and defraying reasonable administrative ' expenses. 29,. U.S.C, § 1104(a)(1). ERISA also prohibits a plan fiduciary from dealing with the assets of the plan in the fiduciary’s own interest and from acting in any. capacity on behalf of a party whose interests are adverse to those of the plan or plan participants. 29 U.S.C. § 1106(b)(1), (b)(2).
Thus, for example,. the Third Circuit held that the trustees for two jointly administered plans violated ERISA by causing one plan to make a loan to the other. Cutaiar v. Marshall, 590 F.2d 523, 529 (3d Cir. 1979) (“When identical trustees of two employee benefit plans whose participants and beneficiaries are not identical effect a loan between the plans without a § 408 exemption, a per se violation of ERISA exists,”). The Third Circuit so held even though there was a “large overlap” in the *844plans’ participants and even though the terms of the loan were fair and reasonable with respect to both plans. Id. at 525, 528. As the Third Circuit explained, “each plan deserves more than a balancing of interests”; instead, “[e]ach plan must be represented by trustees who are free to exert the maximum economic power manifested by their fund whenever they are negotiating a commercial transaction.” Id. at 530.
Similarly, the Fourth Circuit found that an insurer who obtained a release from a participant in relation to one plan could not, consistently with its fiduciary duties, rely on that release to deny benefits to that participant under a different plan. Barron v. UNUM Life Ins. Co. of Am., 260 F.3d 310, 316 (4th Cir. 2001). Because the insurer obtained the release in its capacity as a fiduciary for the first plan, the release was solely for the benefit of that plan, and it would violate ERISA for the release to inure to the insurer’s own benefit in connection with its administration of the second plan. Id. As the Fourth Circuit explained, the insurer’s “duty as administrator of the Comcast Plan must not be confused with its duties as administrator of other plans and must not be compromised by its interest in administering other plans.” Id.
In light of this case law and the strict fiduciary duties imposed by ERISA, cross-plan offsetting is, to put it mildly, a troubling use of plan assets — one that is plainly in tension with “the substantive or procedural requirements of the ERISA statute ...Finley, 957 F.2d at 621. In stark terms, cross-plan offsetting involves using assets from one plan to satisfy debt allegedly owed to a separate plan — a practice that raises obvious concerns under §§ 1104 and 1106. These concerns are particularly acute in this case, in which every offset that United orchestrated did not just benefit a different, unrelated plan, but benefited United itself.
Cross-plan offsetting creates a substantial and ongoing conflict of interest for claims administrators who, like United, simultaneously administer both self-insured and fully insured plans. Recall that nearly a quarter of all claim payments come out of United’s own pocket. As the single biggest payor of claims, United’s personal stake in cross-plan offsetting dwarfs that of any self-insured plan. An administrator in this circumstance has every incentive to be aggressive about looking for overpay-ments from its own fully insured plans (which overpayments can be recovered from self-insured plans) and less aggressive about looking for overpayments from self-insured plans (which overpayments might be recovered from fully insured plans). And indeed, this incentive is reflected in United’s internal documents, which enthusiastically describe how cross-plan offsetting will permit United to reach into the pockets of the sponsors of self-insured plans to recover the overpayments that United makes in connection with fully insured plans.
Cross-plan offsetting may nevertheless be permitted under ERISA. It is undoubtedly true, as United argues, that cross-plan offsetting can benefit plan participants through administrative savings and increased recoveries. It is also undoubtedly true, as United is reluctant to acknowledge, that cross-plan offsetting can harm plan participants. As described above, a provider such as Dr. Peterson who disputes that he has been overpaid by Plan A and who treats a patient insured by Plan B (a “Betsy”) may decide not to accept payment from Plan B in the form of the cancellation of a debt that he does not believe he owes to Plan A. The provider may instead choose to balance bill Betsy, as she bears ultimate legal responsibility for paying the bill. Thus, Betsy — who, under the terms of her Plan B, is entitled to have her provider paid — can find herself *845drawn into a dispute about whether her provider was in fact overpaid when, weeks or months earlier, he submitted a claim for treating a different patient under a different plan.9
It is fairly debatable whether cross-plan offsetting is ever permissible under ERISA. (That issue is not presently before the Court.) It is not fairly debatable, however, that the type of cross-plan offsetting challenged in this case — that is, cross-plan offsetting engaged in by an administrator who insures some (but not all) of the plans — presents a grave conflict of interest. In such a situation, ERISA would seem to require that the administrator (at a minimum) identify the potential costs and benefits of cross-plan offsetting to each plan and, after carefully weighing those costs and benefits, decide whether engaging in cross-plan offsetting is in the best interests of that plan.
Cross-plan offsetting may be in the best interests of the participants of some plans (say, large national plans that make a lot of overpayments because participants are treated by numerous providers who are careless when submitting claims), but not in the best interests of the participants of other plans (say, small local plans that make few overpayments because participants are treated by a only a few providers who are careful when submitting claims). At a minimum, a fiduciary of a plan is obligated under ERISA to make a careful and fully informed decision about whether engaging in cross-plan offsetting is in the best interests of the participants in that plan. This is not the same as deciding whether engaging in cross-plan offsetting is in the best interests of the administrator itself — or in the best interests of other plans. See 29 U.S.C. § 1104(a) (“a fiduciary shall discharge his duties with respect to a plan solely in the interest of the participants and beneficiaries”).
United’s interpretation of the language of the Plan Bs — that is, United’s' position that it has authority to engage in cross-plan offsetting under generic provisions that require United to pay benefits and that grant United discretion to interpret and administer the plans — is problematic not merely because it is in tension with ERISA. United’s interpretation also renders the Plan Bs’ overpayment and recovery provisions meaningless. As discussed above, 40 of the 46 Plan Bs have overpayment and recovery provisions, and 36 of those specifically address offsets. All of the overpayment and recovery provisions— both those that explicitly authorize offsets and those that do not — are triggered only when the Plan B itself has made an overpayment. In addition, only two of the 46 plans (the two that contain provision G) even arguably have language broad enough to permit the plans to recover their overpayments from other plans.
Even if all of the ambiguities in all of the Plan Bs could be stretched to permit the Plan Bs to recover their overpayments from other plans, that would not help United. The issue in this case is not whether the Plan Bs can recover their overpay-ments from other plans; the issue is whether the other plans can recover their overpayments from the Plan Bs. As noted, not a single one of the Plan Bs contains language authorizing such recoveries.
United contends that permission for such recoveries is implicit in the language allowing the Plan Bs to recover from other *846plans. The argument, in essence, is that if a Plan B explicitly authorizes the recovery of its overpayments from other plans, that Plan B must implicitly authorize the other plans to recover their overpayments from the Plan B — because common sense suggests that no plan is going to allow the Plan B to recover its overpayments unless the Plan B reciprocates. This might be a good argument if there were in fact language in a Plan B that made it clear that the Plan B could recover its overpayments from other plans (although it would still be an odd and backhanded way to authorize cross-plan offsetting). But none of the 46 Plan Bs that are at issue in this case have such language. Rather, United relies on generic provisions about paying claims, which United says give it implicit authority to recover the Plan Bs’ overpayments from other plans — and then United doubles down by finding implicit authority within this implicit authority to allow the other plans to recover their overpayments from the Plan B.
United goes too far. Without explicit language authorizing United to recover a Plan B’s overpayments from other plans, United acted unreasonably in interpreting each Plan B to authorize not only that practice, but also the practice of allowing other plans to use the Plan B’s assets to recoup their own overpayments. Again, the vast majority of the plans at issue contain provisions that specifically address offsetting. It would have been easy for the authors of these plans to' authorize cross-plan offsetting — and any prudent fiduciary asked to engage in cross-plan offsetting would insist on such authority, given the tension between engaging in that practice and fulfilling the fiduciary duties imposed by ERISA. The fact that the vast majority of the policies explicitly address the subject of offsetting and do not authorize cross-plan offsetting is powerful evidence that United acted unreasonably in interpreting the plans to permit cross-plan offsetting.
United contends that, under Pilger v. Sweeney, 725 F.3d 922 (8th Cir. 2013), a plan that explicitly authorizes same-plan offsetting cannot be construed to limit the administrator’s ability to engage in cross-plan offsetting. In Pilger, the Eighth Circuit held that an ERISA plan could recoup overpayments that it made to retirees by reducing the retirees’ future benefits. In one short cryptic paragraph that both described and rejected the retirees’ argument to the contrary, the court noted without elaboration .that the plan contained “broad language granting Defendants discretion to take remedial action .Id. at 926. United points out that the Pilger plaintiffs had argued in their appellate brief that the plan’s specific offset provision did not apply in their case and that therefore the plan lacked the authority to take the offsets. First Jacob Decl. Ex. 0 at 18-19. According to United, this means that Pilger stands for the proposition that narrow offset language in a plan does not preclude the administrator from finding broader offset authority in the plan’s generic provisions.
United'reads more into Pilger than it can reasonably bear. The Eighth Circuit nowhere even mentions the offset language on which United’s argument depends. More importantly, the offsets at issue in Pilger involved not only the same plan, but the same beneficiaries. There is nothing particularly unusual or surprising about' a plan having the authority to recoup overpaid benefits from the very beneficiary who received the overpayments, and such a practice (unlike cross-plan offseting) is fully in keeping with the administrator’s fiduciary duties to the plan and its participants. The fact that Pilger found authority to take such offsets in generic remedial language does not mean that it is reasonable to read similar generic language to *847authorize the far more problematic practice of cross-plan offsetting. The Court therefore finds Pilger to be of little help to United.
United also cites Quality Infusion Care, Inc. v. Health Care Service Corp., 628 F.3d 725 (5th Cir. 2010) — a case with facts similar to this one — in which the Fifth Circuit held that the plans at issue authorized cross-plan offsetting. Id. at 729-30. Quality Infusion does not so much as mention ERISA, however, and it relies almost entirely on the absence of language prohibiting cross-plan offsetting. Id. at 729 (noting that the plan “does not specify that the overpayment must be offset against the same patient’s future claim”); id. at 730 (“No language in any of the three plans require BCBS to confine its contractual setoff rights to deductions from subsequent benefit payments to the same patient or under the same plan.”). Whatever the merits of the Fifth Circuit’s approach, it is not the approach of the Eighth Circuit. Finley requires courts to consider the fiduciary duties imposed by ERISA, as well as other factors ignored by Quality Infusion. See 957 F.2d at 621.
Applying the Finley factors, the Court finds that United’s interpretation is unreasonable. The plans themselves do not authorize cross-plan offsetting. To the contrary, most of the plans contain specific overpayment and recovery language that would be rendered meaningless if United was authorized by the generic clauses that it relies upon to engage in cross-plan offsetting. United has not consistently interpreted any plan language to permit cross-plan offsetting; instead, United first implemented cross-plan offsetting and then, after it got sued, rooted through the lan-guage of the-plans in the hope of finding something that might arguably support the practice. And cross-plan offsetting raises serious concerns under ERISA, especially in this situation, where United administers all of the plans but insures only some of the plans. In light of these factors and the other factors discussed above, the plans cannot reasonably be read to permit cross-plan offsetting.
United raises one last, .argument in favor of finding that the plans permit cross-plan offsetting: According to United, it was the (unconflicted) plan sponsors who directed United to engage in this practice, and United was just following orders. United bases this contention on the February 2007 letter that it sent to its existing clients and on the disclosures that it has since made to (some of) its new clients. As United would have it, then, because it told some of its elients that it was implementing cross-plan offsetting, and because it gave those clients a chance to opt out, the decision to engage in cross-plan offsetting was really the decision of the plan sponsors, not United. Moreover, although new clients are not allowed to opt out of cross-plan offsetting, United contends that, because it discloses ‘the system up front, new clients likewise are responsible for the decision to engage in the practice.
United compares its 2007 letter and opt-out procedure to the “negative consent” procedure approved by the Department of Labor (“DOL”) in several advisory opinions. See DOL Adv. Ops., 2003-09A, 2001-02A, 1997-16A.10 The Court very much doubts that United’s 2007 letter was sufficient to transfer the fiduciary decision to United’s clients under this authority.11 The *848DOL opinions were premised in part on the fact that the companies fully and accurately disclosed all material information to their clients and gave those clients a lengthy period of time — at least 60 days in one case, and up to 120 days in another— to make a decision.12 In addition, there is no suggestion in any of the opinions that the companies attempted to influence their clients’ choices; instead, each company simply provided information and left the choice entirely to the client.
In contrast to those cases, United did not fully and accurately disclose all material information to its clients. Some clients may not have received any information about cross-plan offsetting, and those who did get information were not told that United itself would be the largest single beneficiary of the cross-plan offsetting system that it was proposing. In addition, United gave existing clients only a couple of weeks to decide whether to opt out of the system. Finally, United certainly did not remain neutral and take care to ensure that each client’s decision was truly its own; instead, United “strongly encourage[d]” its clients to participate in cross-plan offsetting. First Jacob Decl. Ex. D at 2605; id. Ex. E (internal United bulletin instructing that clients can be excluded from the new system if they “strongly resist[ ]”). In short, even if the DOL opinions could be considered binding authority, the Court would find that United failed to meet the criteria for shifting United’s fiduciary responsibilities onto its existing clients.
The situation with respect to new clients is murky. As discussed above, it is not clear to whom information about cross-plan offsetting is given when United signs up a new client; in particular, it is not clear whether at any point the information is given to someone with plan-wide authority to authorize cross-plan offsetting. Nor is the timing of the communication clear; for all the Court can tell, the only time that the information is conveyed is during the banking setup process, which appears to be a fairly technical process that may or may not take place before the plan sponsor has already contracted with United. In addition, the evidence of what, exactly, United tells its new clients is vague. Most of the communications are oral and respond to client questions. The only written communication — a communication that has been given to existing clients only since 2010 — mostly addresses technical details of setting up and funding accounts. The single reference to cross-plan offsetting in that communication is buried among these details. See Second Jacob Decl. Ex. X at 3816. There is no indication in the record that United provides a full and accurate discussion of cross-plan offsetting to new clients, tells new clients that United is the single biggest beneficiary of cross-plan offsetting, or identifies the nature or extent of United’s conflict of interest. The Court therefore rejects United’s argument that the decision to engage in cross-plan offsetting is made by plan sponsors rather than by United.
United also points to a provision that appears in certain Administrative Service *849Agreements (“ASAs”) that United has with some of its clients. According to United, this provision directs United to take cross-plan offsets. A representative example of the provision reads as follows:
In some instances, UnitedHealthcare may be able to obtain Overpayment recoveries by applying (or offsetting) the Overpayment against future payments to the provider made by Uni-tedHealthcare. In effectuating Overpayment recoveries through offset, UnitedHealthcare will follow United-Healthcare’s established Overpayment recovery rules which include, among other things, the prioritization of Overpayment credits based on the age of the Overpayment in UnitedHealth-eare’s system and funding type.
First Jacob Decl. Ex. J at 28516.
Contrary to United’s contention, this provision does not direct United to engage in cross-plan offsetting. Indeed, this provision does not direct United to do anything; it simply states that United “may” recover overpayments through offsetting. Moreover, this provision does not actually describe the practice of cross-plan offsetting. The closest it comes to doing so is by referring to prioritizing credits based on “funding type,” which may be a vague allusion to the distinction between fully insured and self-insured plans. In short, the language, in the ASAs does not come close to establishing that it is the plan sponsors, rather than United, that exercise the fiduciary discretion to engage in cross-plan offsetting.
Even if United’s 2007 letter to its existing clients, its subsequent disclosures to (some of) its new clients, and the language in (some of) the ASAs were sufficient to shift responsibility for the fiduciary decision from United to its clients, the Court would still find that the plans cannot reasonably be read to permit cross-plan offsetting. True, if the plan sponsors actually made the decision to participate in cross-plan offsetting, that would alleviate the concern about United’s initial conflict of interest. As noted, however, United labors under a continuing conflict of interest in administering the cross-plan offset system because United fully insures some but not all of the plans. More importantly, the fact remains that cross-plan offsetting is in tension with ERISA’s fiduciary rules, is not provided for in the plans, and is at odds with the specific offset language contained in most of the plans. As a result, United did not act reasonably in interpreting the Plan Bs that are at issue in this case to permit cross-plan offsetting. The Court therefore grants plaintiffs’ motions for partial summary judgment and denies United’s motions for full summary judgment.

C. Certification for Immediate Appeal

Under 28 U.S.C. § 1292(b), a district judge may certify an otherwise unappeala-ble order for immediate appeal if the order “involves a controlling question' of law as to which there is substantial ground for difference of opinion” and “an immediate appeal from the order may materially advance the ultimate termination of the litigation .... ” The Court finds that these criteria are met in this ease.
The Court recognizes that interlocutory appeals are discouraged and should be authorized only sparingly and in extraordinary cases. Union Cty., Iowa v. Piper Jaffray & Co., 525 F.3d 643, 646 (8th Cir. 2008). In fact, the undersigned has never certified an order for interlocutory appeal during his almost 11 years on the bench. This case, however, represents the rare case in which interlocutory appellate review is warranted.
This order resolves a controlling and dispositive question of law: whether United acted reasonably in interpreting the plans to permit cross-plan offsetting. See Kennedy v. Georgia-Pacific Corp., 31 F.3d *850606, 609 (8th Cir. 1994) (appellate courts review the district court’s application of the abuse-of-discretion standard in ERISA cases de novo). There is also a substantial ground for difference of opinion: The practice of cross-plan offsetting presents an issue of first impression in the Eighth Circuit and the sole extra-circuit authority to address the practice found that it was permissible.
In addition, conclusively resolving this threshold question would greatly advance the termination of this litigation. If, as United contends, the plans authorize cross-plan' offsetting, this litigation will be over as a practical matter, as it will be very difficult for plaintiffs to hold United liable for doing what the plans authorized it to do. But if, as plaintiffs contend and as the Court has found, the plans do not authorize cross-plan offsetting, then the parties and the Court will face years of extraordinarily complex and expensive discovery, non-dispositive motion practice, litigation over class certification, dispositive-motion practice, trial, and litigation over remedies. The parties have already pointed to a host of complicated legal issues that the Court will 'have to address in these actions — and these actions represent just two of many related actions that are pending in this District.
Finally, this is an exceptional case. United is, by far, the largest health insurer in the United States, and it is one of a handful of the largest health insurers in the world. United' has engaged in cross-plan offsetting for the past decade. If United is ultimately enjoined from engaging in the practice, United will have to undertake the extremely .expensive and disruptive process of unwinding its cross-plan offsetting practice. Having lost its. initial (and, it appears to the Court, strongest) argument in favor of cross-plan .offsetting, United now faces a lengthy period of uncertainty concerning a major component of its business. Immediate appellate review of this issue would not only significantly advance the litigation, but also reduce the time that United will spend in legal limbo.
For these reasons, the Court will certify this order for immediate appeal. ■
ORDER
Based on the foregoing, and on all of the files, records, and proceedings herein, IT IS HEREBY ORDERED THAT:
1. Defendants’ motions for summary judgment [ECF No. 122 in 14-CV- ■ 2101, ECF No. 69 in 15-CV-3064] are DENIED.
2. Plaintiffs’ motions for summary judgment on Phase I issues [ECF No. 140 in 14-CV-2101, ECF No; 87 in 16-CV-3064] are GRANTED.
3. Pursuant to 28 U.S.C. § 1292(b), the Court certifies this order for immediate ' appeal. Any party wishing to take an appeal must, pursuant to § 1292(b), 'apply to the United States Court of Appeals for the Eighth Circuit within 10 days of the date of this order. If the Eighth Circuit accepts the appeal, the Court will stay this case pending the out- ' come of the appeal.

. There appears to be some confusion concerning the total number of plans at issue. Plaintiffs assert that there are 60 Plan As and 59 Plan Bs. See ECF No. 142 at 2. Defendants initially asserted that there are 46 Plan Bs, but later indicated that there are 51 Plan Bs. Compare ECF No. 124 at 2 with ECF No. 150 *838at 1. So far as the Court can tell from studying the charts set forth in the parties' third stipulation regarding Phase I proceedings [ECF No. 120] — and assuming that minor discrepancies in punctuation and the like do not indicate separate plans — there are 46 Plan Bs. ECF No, 120 Ex. A, (Except where indicated, all ECF citations are to documents in the Peterson case. Pincites refer to the internal pagination of such documents.)

. Riverview brings its action as the assignee of its patients’ benefit claims. Dr. Peterson brings his action as the authorized representative of eight of his patients. At an earlier hearing, the Court expressed concern about the extent of Dr. Peterson's disclosures to his patients concerning the potential conflict in this litigation between his interests and his patients’ interests. Having reviewed the full extent of Dr. Peterson’s disclosures, see Meyer Decl. Exs. N, O; ECF No. 109 at 3-4, the Court's concerns are- satisfied. Accordingly, the Court rejects United’s argument that Dr. Peterson lacks authority to bring this action on behalf of his patients.

. Plaintiffs contend that United engaged in cross-plan offsetting as early as 2004, long before it notified its clients of the practice in February 2007. But the evidence that plaintiffs cite, see ECF No. 142 at 8, does not support their contention.

. The parties dispute how many of the plans that are at issue in this case were existing clients and therefore received the 2007 letter disclosing the change. United contends that a “majority” of the plans received the letter, but the evidence that United cites indicates that only 21 of the plans received the letter. See Vang Decl. ¶¶ 3-4. Whether the number of Plan Bs is 59, 51, or 46, see supra note 1, 21 is still less than half of the plans at issue.

. United contends that the recoveries in this case are not representative of the system as a whole. To support this argument, United offers a one-page summary of figures purporting to represent the amount of fully insured and self-insured payments and offsets in 2015. This one-page document apparently represents the jottings of United's counsel. See Jacob Decl., Apr. 22, 2016 [hereinafter "Second Jacob Decl.”] Ex. T. United does not cite any affidavit or testimony that would establish foundation for this document, nor was the Court able to locate any in the record. (There was some discussion of the document at one deposition, but that discussion is not sufficient to establish foundation. See Bishop-Her-oux Dep. 274-77.) Plainly, then, the document is not admissible.
That said, it is worth noting that, taking the document at face value, the document shows that while United made 22 percent of the claim payments, it received 36 percent of the overpayment recoveries. Thus, whether one credits the plaintiffs’ numbers or United's, cross-plan offsetting benefits United more *841than it benefits the sponsors of self-insured plans.

. The parties have assigned a letter to each of the 16 types of overpayment and recovery provisions. The 17 combinations — and the number of plans that contain each combination — are as follows:

. A number of the plans have coordination-of-benefits clauses providing that United may reimburse another plan under which the participant is covered if the other plan pays a benefit that United should have paid. ECF No. 120 Ex. B at 20. These clauses do not author*842ize the cross-plan offsetting at issue in this case, however.

. United attempts to reframe the issue before tire Court by contending that plaintiffs’ claims for past-due benefits turn solely on the meaning of the word "pay,” and that United has reasonably interpreted “pay” to mean payment through debt cancellation. This argument mischarácterizes the issue. The question is not whether United can, in the abstract, pay a provider who treats a patient insured under a.plan by cancelling the provider’s debt to that plan. The question is whether United, in its capacity as administrator of a Plan B, can pay a provider who treats a patient insured under Plan B by cancelling debt that the . provider allegedly owes to a Plan A — that is, to a different, completely unrelated plan that also happens to-be administered by United.
As an aside, the Court notes that United’s contention that it "pays” providers by cancel-ling debt seems to have a major flaw. It may be reasonable for United to deem the cancellation of an uncontested debt of $100 as providing a $100 “payment” to the debtor. But the debts that matter for purposes of this - litigation are contested. Unless the provider’s grounds for disputing the debt are frivolous, it is not reasonable for United to deem the cancellation of a contested debt of $1,00 as providing a $100 "payment.”

. Of course, this risk is also present with same-plan offsetting. But when a plan engages in same-plan offsetting, all of the advantages of offsetting inure to the plan doing the offsetting. The same cannot be said for cross-plan offsetting, under which some plans .might disproportionately enjoy the benefits and other plans might disproportionately bear the costs.

Notably, under ERISA Procedure 76-1 regarding DOL advisory opinions, ''[o]nly the parties described in the request for opinion may rely on the opinion,” and “only to the extent that the request fully and accurately *848contains all the material facts and representations necessary to issuance of the opinion and the situation conforms to the situation described in the request for opinion.” Employee Benefit Plans, Advisory Opinion Procedure, 41 Fed. Reg. 36281, 36283 § 10 (Aug. 27, 1976).

. In one of the cases, either party could have terminated the relationship with 30 days’ written notice, but that appears to have been the result of a contractual provision to which both parties agreed. DOL Adv. Op. 2003-09A. In the same case, the trustee-service company provided 60 days' written notice of proposed fee adjustments.
