Opinion by Judge Berzon

SUMMARY **

Employee Retirement Income Security Act / Preemption

The panel affirmed in part and reversed in part the district court’s dismissal and remanded for further proceedings in an action brought under the Employee Retirement Income Security Act (“ERISA”) and California state law by Healthcare Ally Management of California, LLC (“HAMOC”), against WSP USA, Inc., and Aetna Life Insurance Co.

The case arose from a dispute over the proper payment rate for a surgery that took place at the La Peer Surgery Center. At the time, the patient was enrolled in an ERISA healthcare plan provided by the patient’s employer, WSP, and Aetna administrated the plan. Before providing out-of- network surgical services, La Peer placed a verification call to Aetna, which told La Peer that the patient would cover a portion of the surgery but that WSP’s plan would pay the remaining balance at the usual, customary, and reasonable rate and that payment would not be based on the Medicare fee schedule. Contrary to Aetna’s representation, however, WSP paid La Peer not at the USR rate, but at the Medicare rate, which amounted to five percent of La Peer’s bill.

HAMOC, La Peer’s successor in interest, brought suit. The district court held that HAMOC lacked derivative

standing to assert an ERISA claim on La Peer’s behalf and dismissed that claim. The district court dismissed the remainder of HAMOC’s complaint pursuant to Fed. R. Civ. P. 12(b)(6), concluding that the state law claims necessarily depended on the existence of an ERISA-covered plan and so were preempted by ERISA.

Under 29 U.S.C. § 1144(a), ERISA preempts all state laws that “relate to” any healthcare plan regulated by the statute. The two categories of state-law claims that “relate to” an ERISA plan are claims that have a “reference to” an ERISA plan and claims that have “an impermissible connection with” an ERISA plan.

Reversing in part, the panel held that ERISA did not preempt HAMOC’s negligent misrepresentation claim, which arose from coverage representations made to an out- of-network medical provider during a verification call in advance of medical services. Because this claim did not focus on an ERISA-regulated relationship, it was not preempted under the “connection with” test. Agreeing with other circuits, the panel concluded that the negligent misrepresentation claim was not preempted under the “reference to” test because it was not a claim that Congress could have intended to route through ERISA’s civil enforcement scheme. Rather, HAMOC was simply an independent entity claiming damages. The panel explained that the result it reached accorded with the underlying premises of ERISA preemption. The panel distinguished Bristol SL Holdings, Inc. v. Cigna Health & Life Ins. Co., 103 F.4th 597 (9th Cir. 2024), which held that ERISA preempted state law breach of contract and promissory estoppel claims.

Affirming in part, the panel held that under Bristol, ERISA preempted HAMOC’s California state law claim of promissory estoppel.

OPINION

BERZON, Circuit Judge:

The Employee Retirement Income Security Act of 1974 (“ERISA”) contains a provision that expressly preempts all state laws that “relate to” any healthcare plan regulated by the statute. 29 U.S.C. § 1144(a). We consider whether ERISA preempts a state law negligent misrepresentation claim that arises from coverage representations made to an out-of-network medical provider in advance of medical services. We hold that ERISA does not preempt the claim and so reverse.

Center. 1 At the time, the patient was enrolled in an ERISA healthcare plan provided by the patient’s employer, defendant WSP USA, Inc. Defendant Aetna Life Insurance Company administered WSP’s healthcare plan by coordinating with medical providers like La Peer and processing those providers’ reimbursement claims under the terms of WSP’s health benefit plan.

As is common practice in the health insurance industry, WSP’s healthcare plan differentiated “in-network” providers from “out-of-network” providers, a distinction that determines how the plan reimburses providers for the medical services they perform. In-network providers enter written preferred-provider contracts with healthcare plans and agree to accept discounted reimbursements for their services. In exchange for these discounts, the plans provide incentives for their members to seek in-network treatment, thereby increasing the total volume of an in-network provider’s business.

By contrast, out-of-network providers do not have preexisting contractual agreements in place with a given healthcare plan. Insurers often reimburse out-of-network providers a percentage of the market rate for a given procedure, but such providers can charge higher rates because, unlike in-network providers, they have not agreed in advance to accept discounted reimbursements. Out-of- network providers typically receive from insurers the

“Usual, Customary, and Reasonable” (“UCR”) rate for their services, a term that denotes the average amount paid for a specific procedure in a given geographic area based on what other providers in that area charge for the same service, but Medicare coverage can affect whether the UCR rate applies. 2 Because out-of-network providers lack contractual reimbursement agreements with healthcare plans, they often place a “verification call” to the plan administrator before performing a procedure to confirm that the patient is eligible for coverage, to ascertain that the particular procedure is covered, and to learn the likely reimbursement rate.

La Peer provided out-of-network surgical services for the patient in this case. 3 Before doing so, La Peer placed a verification call to Aetna to confirm that the patient’s plan would pay the surgery center for the procedure. On that call, Aetna told La Peer that the patient would cover a portion of the surgery as an out-of-pocket expense but that WSP’s plan would pay the remaining balance at the UCR rate. 4 Aetna
