MEMORANDUM AND ORDER

ROSENSTENGEL, District Judge:

Marion HealthCare, LLC, and Marion Anesthesia Company, LLC (“Plaintiffs”), initiated this civil action against Defendants Aisin Manufacturing Illinois, LLC (“Aisin”), and Anthem Blue Cross and Blue Shield a/k/a HMO Missouri, Inc. (“Anthem Blue Cross”). Defendants Aisin and Anthem Blue Cross have both separately filed motions to dismiss for lack of subject matter jurisdiction and for Plaintiffs’ failure to comply with Rules 8, 9, 10, and 12 of the Federal Rules of Civil Procedure. (Docs. 30, 32). For the reasons set forth below, the Court grants Defendants’ Motions to Dismiss Plaintiff’s Second Amended Complaint. BACKGROUND Plaintiffs are Illinois-based healthcare providers. (Doc. 23 at p. 1). Defendant Aisin employs 65 individuals who receive health benefits and insurance through an employer- sponsored group health plan (“Plan”) administered by Anthem Blue Cross. (Doc. 23 at pp. 1- 2). The Plan is self-funded by Aisin and is an employee welfare plan as defined by The Employee Retirement Security Act of 1974, as amended (“ERISA”), 29 U.S.C. §1002 et seq. On or around January 17, 2025, an unidentified and unnamed individual, Jane Doe,

either contacted Anthem Blue Cross via phone call or accessed information via the Internet in order to verify health insurance coverage regarding upcoming medical services. (Id. at p. 7). During this phone call or online verification procedure, Anthem Blue Cross represented that Jane Doe was covered under the Plan and did not disclose any applicable limitation on coverage. (Id). After Jane Doe received medical services from Plaintiffs on January 27, 2025, Plaintiffs issued a medical bill to Aisin and Anthem Blue Cross. (Id. at p. 2). The charges for the services

rendered to Jane Doe totaled $14,355.00; however, Aisin only paid $449.99 to Marion HealthCare. (Id). Similarly, Marion Anesthesia’s charges amounted to $760, yet they did not receive any payment from Aisin for the services performed. (Id). Before receiving the medical services, Jane Doe attempted to execute an assignment of her benefits, claims, and causes of action under the Plan to Plaintiffs. (Id. at p. 2). Between 2023 and 2025, 64 other unnamed individuals, who were also Aisin employees and Plan participants, sought and received medical services from Plaintiffs. (Id. at

p. 7). Like the aforementioned Jane Doe, these individuals verified their insurance coverage through a phone call to Anthem Blue Cross or via an online verification procedure, and also attempted to assign their benefits to Plaintiffs. (Id). The total sum of charges for the healthcare services provided to the 64 individuals and Jane Doe amounted to $895.454.77. (Id). Yet, Defendant Aisin only paid Plaintiffs $183,684.29. (Id). Before initiating this suit, Plaintiffs exhausted their assigned appeal rights and procedures and Defendants’ alleged underpayment for the medical services provided was not rectified. (Id). Based on these allegations, Plaintiffs bring various claims against Aisin and Anthem Blue Cross for violations of ERISA along with claims of fraud and promissory estoppel under

state law. (Doc. 23). Plaintiffs seek payment of the unpaid and underpaid claim balances under the Plan for the medical services provided, costs of suit including attorneys’ fees, economic damages, and punitive damages. (Id). Aisin and Anthem Blue Cross have both moved to dismiss Plaintiffs’ Second Amended Complaint, arguing that this Court lacks subject matter jurisdiction over Plaintiffs’ claims because Plaintiffs lack standing. Defendants also move to dismiss for improper venue, preemption, and failure to state a claim. (See Docs. 29, 30, and 32).

LEGAL STANDARD A court facing a challenge to subject matter jurisdiction under Federal Rule of Civil Procedure 12(b)(1) must determine whether the party is raising a facial or factual challenge. Silha v. ACT, Inc., 807 F.3d 169, 173 (7th Cir. 2015). A factual challenge alleges that, even if the pleadings are sufficient, there is no basis for subject matter jurisdiction. Id. A facial challenge, on the other hand, argues the plaintiff has not sufficiently pleaded a basis for subject matter jurisdiction. Id. “In reviewing a facial challenge, the court must accept all well-pleaded factual

allegations as true and draw all reasonable inferences in favor of the plaintiff.” Id. Federal Rule of Civil Procedure 12(b)(6) requires that a plaintiff allege enough facts to state a claim for relief that is plausible on its face. Bell Atlantic Corp. v. Twombly, 550 U.S. 544, 570 (2007). There need not exist detailed factual allegations, however, there “must be enough to raise a right to relief above the speculative level.” Id. at 555. The plaintiff must provide the Court with “more than labels and conclusions, and a formulaic recitation of the elements.” Id. at 570. When evaluating a motion to dismiss under Rule 12(b)(6), the Court must accept all well-pleaded facts as true and draw all possible inferences in favor of the plaintiff. McReynolds v. Merrill Lynch & Co., Inc., 694 F.3d 873, 879 (7th Cir. 2012).

In evaluating a complaint on a motion to dismiss, “district courts are free to consider ‘any facts set forth in the complaint that undermine the plaintiff’s claim.’” Esco v. City of Chicago, 107 F.4th 673, 678 (7th Cir. 2024) (quoting Bogie v. Rosenberg, 705 F.3d 603, 609 (7th Cir. 2013)). “The court, therefore, may examine exhibits, including video exhibits, attached to the complaint, or referenced in the pleading if they are central to the

claim.” Id.; see also Tierney v. Vahle, 304 F.3d 734, 738 (7th Cir. 2002) (explaining that a court may consider exhibits referred to in a complaint, even if not attached to it, as “plaintiff could evade dismissal under Rule 12(b)(6) simply by failing to attach to his complaint a document that proved that his claim had no merit”). DISCUSSION I. Standing Counts I and II of this suit are brought under The Employment Retirement Income
