OPINION _________________

BLOOMEKATZ, Circuit Judge. Tiara Yachts, Inc., hired Blue Cross Blue Shield of Michigan (“BCBSM”) to administer its self-funded healthcare benefits plan. It alleges that BCBSM knowingly squandered plan assets by systematically overpaying some categories of No. 24-1223 Tiara Yachts, Inc. v. Blue Cross Blue Shield of Mich. Page 2

claims. BCBSM then allegedly profited from its mismanagement by implementing a program through which it caught overpayments, clawed them back, and kept a portion of those “savings” for itself.

Tiara Yachts sued BCBSM under the Employee Retirement Income Security Act (“ERISA”), 29 U.S.C. § 1001, et seq., and BCBSM moved to dismiss. The district court granted that motion, holding that Tiara Yachts hadn’t plausibly alleged that BCBSM acted as an ERISA fiduciary. It also held that ERISA’s remedial provisions couldn’t provide the relief Tiara Yachts sought. Because the district court erred on both fronts, we reverse.

BACKGROUND1

I. The Administrative Services Contract

Tiara Yachts is a Michigan corporation that designs and manufactures boats. It offers its employees health insurance through a self-funded benefits plan (“the Plan”). So rather than buying health insurance from another company, Tiara Yachts pays a portion of its employees’ actual medical costs according to the Plan’s terms.

In January 2006, Tiara Yachts hired BCBSM to administer the Plan. An Administrative Services Contract (“ASC”) governed their relationship. Under that contract, BCBSM was responsible for interpreting the Plan’s terms, calculating benefits, deciding whether to grant or deny claims on Tiara Yachts’ behalf, and ultimately paying providers. In exchange, Tiara Yachts paid BCBSM a monthly fee and periodically deposited money into a BCBSM-owned account, from which BCBSM paid claims. That meant BCBSM decided what claims to pay and for how much, then wrote checks to medical providers out of the Plan’s assets.

The ASC granted Tiara Yachts some ways to oversee BCBSM’s management of the Plan. For example, the contract allowed Tiara Yachts to dispute any claim BCBSM paid within sixty days. It also allowed Tiara Yachts to request an audit of claims from the preceding twenty-four months.

1 We accept Tiara Yachts’ factual allegations as true and draw all reasonable inferences in its favor, as we must at this stage. Linden v. City of Southfield, 75 F.4th 597, 601 (6th Cir. 2023). No. 24-1223 Tiara Yachts, Inc. v. Blue Cross Blue Shield of Mich. Page 3

Tiara Yachts renewed the ASC annually until December 2018, when it terminated its relationship with BCBSM.

II. “Flip Logic” and Overpaying Claims

Tiara Yachts alleges that BCBSM systematically overpaid claims submitted by medical providers during the years that BCBSM administered the Plan. Understanding Tiara Yachts’ allegations requires some background. BCBSM is just one of thirty-eight Blue Cross Blue Shield Association regional affiliates—colloquially known as the “Blues.” Each of the Blues negotiates with providers in its area to set rates for medical services. Although the Blues operate independently, they process claims and reimbursements through a central electronic system. And the Blues have a policy that allows individuals enrolled in one Blue’s plan to receive the benefit of another “Host Blue’s” pricing if they need out-of-state medical care. In that scenario, the insuring Blue reimburses the out-of-state medical provider at the rate the Host Blue would pay. When contracting with BCBSM, Tiara Yachts secured this benefit for its Plan’s participants. Thus, for example, when a covered Tiara Yachts employee received care in another state—say, Tennessee—BCBSM promised Tiara Yachts that it would reimburse the provider at whatever rate Tennessee’s Blue would pay.

But that is not what happened. Instead, BCBSM processed claims using an “intentional design” called “flip logic.” Compl., R. 1, PageID 7. How did it work? When an out-of-state provider who wasn’t part of the Host Blue’s network submitted a claim, BCBSM would “flip” its status and reimburse the provider however much it charged rather than at the Host Blue’s lower rate.2 As a result, BCBSM reimbursed “many times over and above the customary amount for such services.” Id. at PageID 8. BCBSM implemented flip logic in 1997, long before Tiara Yachts hired it to administer the Plan.

According to internal emails between BCBSM employees, flip logic affected “all” customers on one of BCBSM’s claims-processing platforms except those purchasing auto insurance. See Sept. 14 Email Chain, R. 1-2, PageID 27. Though the emails do not name any

2 The exact mechanics of “flip logic” are not necessary to analyzing Tiara Yachts’ claims. At bottom, Tiara Yachts alleges that flip logic caused BCBSM to overpay on claims from certain out-of-state providers. No. 24-1223 Tiara Yachts, Inc. v. Blue Cross Blue Shield of Mich. Page 4

customers, Tiara Yachts was a customer on that platform and did not purchase auto insurance. By 2017, BCBSM knew that flip logic allowed “abusive provider practices” that resulted in reimbursements “far exceed[ing]” the “allowed amount.” See id. Despite that knowledge, BCBSM didn’t implement “controls in the system logic that would flag suspicious claim activity.” Compl., R. 1, PageID 8.

The issues with BCBSM’s claims processing extended beyond flip logic. The platform BCBSM used to manage claims for all similarly situated customers, including Tiara Yachts, allegedly suffered from “processing errors” that allowed providers to improperly code for their services and overbill the Plan, which “consistently result[ed] in improper payments of claims.” Id. at PageID 15–16. Tiara Yachts does not cite specific claims that BCBSM overpaid from Plan assets. But that’s because, Tiara Yachts says, BCBSM concealed flip logic from its customers and limited access to claims data and explanatory documents.

III. Shared Savings Plan

Tiara Yachts further alleges that BCBSM implemented a program to profit from its practice of overpaying claims. Starting in January 2018, BCBSM enrolled all self-funded customers, including Tiara Yachts, in a new “Shared Savings Program” (“SSP”). Under that program, among other things, BCBSM hired third parties to claw back past overpayments from providers and to detect and prevent future overpayments before they occurred. In exchange for those services, BCBSM kept 30% of the payments third parties either recovered or prevented.
