OCT 6 2023 MOLLY C. DWYER, CLERK U.S. COURT OF APPEALS2

28 U.S.C. § 1291. We review de novo the district court’ s dismissal under Federal Rule of Civil Procedure 12(b)(6), DB Healthcare, LLC v. Blue Cross Blue Shield of Ariz., Inc. , 852 F.3d 868, 87 3 n.5 (9th Cir. 2017), and we review for an abuse of discretion the district court’s denial of leave to amend, Or. Clin ic, PC v. Fireman’s Fund Ins. , 75 F.4th 1064, 1073 (9th Cir. 2023). We affirm.
1. The district court did not err by dismissing Plaintiff’s complaint under Rule 12(b)(6) because (1) Plaintiff lacks derivative authority to sue under the Employee Retirement Income Security Act of 1974 (“ERISA”), and (2) Plaintiff failed to plead ERISA claims sufficiently

. First, Plaintiff lacks derivative authority to bring ERISA claims as a second assignee. Under 29 U.S.C. § 1132(a)(1)(B), only a “participant or b eneficiary” has authority to sue to recover ERISA benefits. A n exception allows health care providers to sue on their patients’ behalf if the patients assign their claims to the provider in exchange for health care. That exception furthers ERISA’s purpose of protecting employees’ rights to health benefits. Simon v. Value Behav. Health, Inc. , 208 F.3d 1073, 1081 (9th Cir. 2000), overruled on other grounds by Odom v. Microsoft Corp. , 486 F.3d 541 (9th Cir. 2007). But where, as here, a health care provider rea ssigns its patients’ claims to a non

- provider third party that has no relationship to the patients, the third party cannot file those claims on behalf of the3

patients. Id

. 1 Because allowing this type of transaction “would be tantamount to transforming health benefit claims into a freely tradable commodity,” id. , Plaintiff lacks authority to sue. Second, even if Plaintiff had authority to sue, it failed to plead ERISA claims

a dequately . After years of litigation and multiple amended complaints, Plaintiff

asserts near

- identical, generalized allegations on information and belief against all Defendants. But the allegations do not identify any Defendant’s particular plan terms conf erring a benefit on patients, nor do they specify any Defendant’s particular conduct in denying such a benefit. See, e.g. , Doe v. CVS Pharmacy, Inc. , 982 F.3d 1204, 1213 (9th Cir. 2020) (holding that, to plead a claim under 29 U.S.C. § 1132(a)(1)(B), a “pl aintiff must allege ‘the existence of an ERISA plan,’ and identify ‘the provisions of the plan that entitle [the plaintiff] to benefits’” (quoting Almont Ambulatory Surgery Ctr., LLC v. UnitedHealth Grp., Inc. , 99 F. Supp. 3d 1110, 1155 (C.D. Cal. 2015))). Plaintiff need not recite every relevant term of every relevant plan, but it must do more than broadly allege that dozens of insurers with distinct plans all violated the same generalized obligation to reimburse mental health

1 Plaintiff argues that this court should apply Bristol SL Holdings, Inc. v. Cigna Health & Life Ins. Co. , 22 F.4th 1086 (9th Cir. 2022) , to expand third

- party derivative authority to bring ERISA claims. But Bristol only “modest[ly]” extended derivative authority to a health care provider’s successor

- in

- interest through bankruptcy proceedings under “unique circumstance[s]” that do not exist here. Id. at 1091, 1092.4

and substance abuse treatment

. E.g. , Ashcroft v. Iqbal , 556 U.S. 662, 678 (2009) ( holding that Rule 8’s pleading standard “does not require ‘detailed factual allegations,’” but it “demands more than an unadorned, the

- defendant

- unlawfully

harmed

- me accusation” (quoting Bell Atl. Corp. v. Twombly , 550 U.S. 544, 555 (2007))).
2. The district court did not abuse its discretion by denying leave to amend. Plaintiff forfeited any challenge to the district court’s denial of leave to amend by failing to raise the issue in its opening brief. Smi th v. Marsh , 194 F.3d 1045, 1052 (9th Cir. 1999).
AFFIRMED.
