ERISA Preempts State PBM “Any-Willing-Provider” and Anti-Steering Incentive Restrictions that Dictate Pharmacy Network Design and Cost-Sharing
Case: McKee Foods Corp. v. BFP Inc. (6th Cir. Apr. 7, 2026) |
Court: United States Court of Appeals for the Sixth Circuit |
Panel: McKeague, Readler, and Davis, JJ.
1. Introduction
This Sixth Circuit decision sits at the intersection of (i) growing state efforts to regulate pharmacy benefit managers (PBMs)
and (ii) the Employee Retirement Income Security Act of 1974 (ERISA)’s broad preemption of state laws that intrude into the
structure or administration of employer-sponsored benefit plans. The plaintiff, McKee Foods Corporation, sponsors and administers
a self-funded ERISA health plan and uses a PBM (MedImpact) to help administer prescription-drug benefits and pharmacy networks.
Tennessee enacted PBM-focused laws—first Public Chapter 569 (2021), then Public Chapter 1070 (effective Jan. 1, 2023)—aimed at
reducing “steering” to PBM-affiliated pharmacies and protecting smaller/rural pharmacies. The statutes did so chiefly by:
(a) imposing “any-willing-provider” (AWP) style access rules for pharmacy networks, and (b) restricting differential cost-sharing
and incentives tied to pharmacy choice.
The core issue was whether ERISA preempts these Tennessee PBM laws when applied to self-funded ERISA plans and their PBMs—particularly
in light of the Supreme Court’s decision in Rutledge v. PCMA, 592 U.S. 80 (2020), which upheld an Arkansas PBM
reimbursement-rate law against an ERISA preemption challenge.
2. Summary of the Opinion
The Sixth Circuit affirmed a permanent injunction prohibiting Tennessee’s Insurance Commissioner from enforcing the challenged PBM
provisions against McKee’s self-funded ERISA plan (directly) or against its PBM (indirectly, for actions taken on the plan’s behalf).
The court held that Tennessee’s PBM laws have an impermissible “connection with” ERISA plans because they:
- require plans to be structured in particular ways (especially regarding pharmacy network composition and cost-sharing),
- govern central matters of plan administration (pharmacy network design and benefit incentives), and
- interfere with nationally uniform plan administration by forcing state-specific plan tailoring.
The court also resolved threshold justiciability and enforcement-path questions in McKee’s favor, holding that McKee (as a plan
fiduciary) could proceed and had standing to bring a pre-enforcement challenge, and that Ex parte Young
allowed prospective injunctive relief against the Commissioner.
3. Analysis
3.1. Precedents Cited (and How They Shaped the Decision)
Organizing principle: The panel treats Rutledge v. PCMA as the key modern baseline:
states may regulate PBM reimbursement and similar cost measures, but they cross the ERISA line when they dictate benefit design,
network structure, or core administrative choices for self-funded plans.
-
Rutledge v. PCMA, 592 U.S. 80 (2020)
Role: The Commissioner invoked Rutledge as permission for broader PBM regulation. The Sixth Circuit instead used Rutledge’s
framework to distinguish permissible “cost regulation” from impermissible dictation of plan structure. Rutledge’s “connection with”
tests—state laws that (i) mandate plan structures, (ii) bind administrators to benefit choices, (iii) govern central plan administration,
or (iv) disrupt national uniformity—anchored the preemption analysis. The panel held Tennessee’s laws were unlike Rutledge’s
reimbursement tethering because they compelled network inclusion and flattened cost-sharing differentials across pharmacies.
-
Gobeille v. Liberty Mut. Ins. Co., 577 U.S. 312 (2016)
Role: Provided the “central matter of plan administration” and “nationally uniform plan administration” concepts. The panel
leaned on Gobeille to emphasize ERISA’s goal of avoiding a 50-state compliance patchwork for plan administrators.
-
Shaw v. Delta Air Lines, Inc., 463 U.S. 85 (1983)
Role: Supported the proposition that ERISA preemption reaches state laws that prohibit employers from structuring plans in
certain ways—here, Tennessee’s laws effectively removing the plan’s discretion to design a limited or tiered pharmacy network.
-
N.Y. State Conf. of Blue Cross & Blue Shield Plans v. Travelers Ins. Co., 514 U.S. 645 (1995)
Role: Used both for the “bind plan administrators to a particular choice” phrasing and for the caution that not every
cost impact triggers preemption; only sufficiently “acute” impacts that effectively dictate plan choices do. The panel used Travelers
to differentiate ordinary economic effects from network-design mandates.
-
Cal. Div. of Lab. Standards Enf't v. Dillingham Constr., N.A., Inc., 519 U.S. 316 (1997)
Role: Supplied the “nature of the effect” lens for “connection with” analysis. Tennessee’s statutes were judged by their
functional effect on plan administration and benefit design.
-
Egelhoff v. Egelhoff ex rel. Breiner, 532 U.S. 141 (2001)
Role: Reinforced the patchwork concern: state-by-state variations force administrators to track, update, and litigate diverse
state rules—exactly what ERISA seeks to prevent. The panel used Egelhoff to underscore why Tennessee-specific network rules are
preempted even if framed as PBM regulation.
-
Kentucky Ass'n of Health Plans, Inc. v. Nichols, 227 F.3d 352 (6th Cir. 2000), aff'd sub nom. Kentucky Ass'n of Health Plans, Inc. v. Miller, 538 U.S. 329 (2003)
Role: A critical intra-circuit comparator for AWP laws. Nichols held Kentucky AWP statutes “connected with” ERISA plans
because they effectively required purchase of a “certain structure” of benefits by forcing provider inclusion. The panel treated
Tennessee’s AWP provisions as materially similar: they remove the plan’s option to design a narrower network by requiring access for
any pharmacy willing to accept set terms.
-
PCMA v. Mulready, 78 F.4th 1183 (10th Cir. 2023)
Role: Served as persuasive authority aligning with Nichols and the panel’s reading of Rutledge. Mulready treated pharmacy
network composition and differential cost-sharing as “key benefit designs” and held comparable Oklahoma PBM provisions preempted
where they required inclusion in preferred networks and prohibited differential cost-sharing. The Sixth Circuit used Mulready to
reinforce that “anti-steering” and AWP rules can dictate plan design, not merely prices.
-
PCMA v. Dist. of Columbia, 613 F.3d 179 (D.C. Cir. 2010)
Role: Supported the proposition that rules disabling cost-sharing arrangements can operate as regulation of ERISA plans
themselves. The Sixth Circuit used this to frame Tennessee’s incentive provisions as more than ordinary market regulation.
-
Pilot Life Ins. Co. v. Dedeaux, 481 U.S. 41 (1987) and
FMC Corp. v. Holliday, 498 U.S. 52 (1990)
Role: Controlled the saving clause/deemer clause structure. Even assuming Tennessee’s PBM laws “regulate insurance,” the
deemer clause prevents applying such laws to self-funded ERISA plans by “deeming” them insurers.
-
US Airways, Inc. v. McCutchen, 569 U.S. 88 (2013),
Mertens v. Hewitt Assocs., 508 U.S. 248 (1993), and
CIGNA Corp. v. Amara, 563 U.S. 421 (2011)
Role: Used to confirm that injunctions are “typically available in equity,” supporting the availability of equitable relief
under ERISA § 1132(a)(3).
-
Armstrong v. Exceptional Child Ctr., Inc., 575 U.S. 320 (2015) and
Ex parte Young, 209 U.S. 123 (1908)
Role: Provided the doctrinal pathway for suing state officials for prospective equitable relief to stop enforcement of
allegedly preempted state laws (and the general “long history” of such review).
-
Susan B. Anthony List v. Driehaus, 573 U.S. 149 (2014) and
McKay v. Federspiel, 823 F.3d 862 (6th Cir. 2016)
Role: Framed the pre-enforcement standing test and the “credible threat of prosecution” factors. The court found credible
threat based on complaint-driven enforcement mechanisms and the Commissioner’s repeated insistence that ERISA plans were covered.
-
Plan fiduciary status authorities:
Gobeille v. Liberty Mut. Ins. Co., 577 U.S. 312 (2016);
Briscoe v. Fine, 444 F.3d 478 (6th Cir. 2006);
Tiara Yachts, Inc. v. Blue Cross Blue Shield of Mich., 138 F.4th 457 (6th Cir. 2025);
Hunter v. Caliber Sys., Inc., 220 F.3d 702 (6th Cir. 2000);
and the monitoring duty discussion referencing Hughes v. Nw. Univ., 595 U.S. 170 (2022) and
Tibble v. Edison Int'l, 575 U.S. 523 (2015).
Role: These cases supported the functional determination that McKee, which designed and administered key plan features
and made discretionary network decisions (including exclusion of a pharmacy after an audit), qualified as an ERISA fiduciary eligible
to sue under ERISA’s civil enforcement provision.
3.2. Legal Reasoning
A. Threshold holdings enabling the merits decision
-
ERISA cause of action / equitable relief: The court treated ERISA § 1132(a)(3) as providing a viable pathway for
a fiduciary to seek injunctive and declaratory relief. Even while declining to definitively decide whether § 1132(a)(3)(A) covers
preemption claims, it held the suit could proceed under § 1132(a)(3)(B)(ii) (equitable relief to enforce ERISA).
-
Fiduciary status as functional: McKee’s discretionary authority over plan design and pharmacy network administration
made it a fiduciary under 29 U.S.C. § 1002(21)(A), reinforced by the Commissioner’s judicial admission that McKee was a fiduciary.
-
Standing / credible threat in a complaint-driven enforcement scheme: The court credited (i) prior administrative
complaints, (ii) statutory features allowing public initiation of administrative proceedings, and (iii) the Commissioner’s repeated
non-disavowal and affirmative statements that ERISA plans were included, as establishing an imminent enforcement risk.
-
Ex Parte Young: Because McKee sought prospective relief against an ongoing alleged federal-law violation (ERISA
preemption), sovereign immunity did not bar the suit against the Commissioner.
B. Merits: ERISA “connection with” preemption applied to PBM regulation
The court focused on ERISA’s express preemption clause, 29 U.S.C. § 1144(a), and specifically the “connection with” prong
(rather than “reference to”). Following Rutledge v. PCMA, it identified multiple independent ways a state
law can have an impermissible connection with ERISA. The Commissioner largely argued the laws did not bind administrators to a
particular substantive benefits choice; the court held Tennessee’s laws nevertheless failed other “connection with” pathways.
1) Any-Willing-Provider (AWP) provisions
Tennessee’s AWP provisions (Tenn. Code Ann. §§ 56-7-2359, 3120(b)(1), 3121(a) and (b)) were treated as mandating pharmacy network
inclusion—i.e., any Tennessee-licensed pharmacy willing to accept the “same terms and conditions” must be allowed into networks,
including preferred networks. The court reasoned that:
-
They require a particular plan structure: By eliminating the plan’s ability to maintain a limited network (and
thereby leverage network design as a benefit/cost tool), they “require providers to structure benefit plans in particular ways.”
-
They govern a central matter of plan administration: Pharmacy network design is “extremely important” and “central”
to administration; forcing network scope alters plan administration, not merely market conditions.
-
They undermine national uniformity: If replicated across states with variations, administrators would face
state-by-state network mandates, the patchwork burden ERISA was enacted to prevent.
The court aligned this analysis with Kentucky Ass'n of Health Plans, Inc. v. Nichols and found persuasive
support in PCMA v. Mulready, treating AWP rules as benefit-structure mandates rather than permissible pricing
regulation.
2) “Incentive” provisions (anti-steering and cost-sharing uniformity)
Tennessee’s incentive provisions (Tenn. Code Ann. §§ 56-7-3120(a), (b)(2), and 3121(c)) restrict higher copays/coinsurance and other
penalties, and prohibit “financial or other incentives” to persuade beneficiaries to use PBM-owned or plan-owned pharmacies. The court
characterized their functional effect as imposing uniform cost-sharing across the network—because “forbidding differential cost-sharing
structures is the same as requiring identical cost-sharing structures.”
-
They dictate plan benefit design: Differential copays and preferred-tier incentives are core tools for designing
pharmacy benefits; the law removes that design choice.
-
They are not Rutledge-style cost regulation: Unlike reimbursement-rate tethering, these rules affect the plan’s
internal benefit structure and participant-facing incentives in a way the court deemed “so acute” that it effectively dictates plan
choices.
-
Direct reach reinforced by Tennessee’s definitions: Tennessee expanded “covered entity” and “pharmacy benefits manager”
definitions to include ERISA plans and declared the PBM laws apply to ERISA plans “notwithstanding another law,” sharpening the ERISA
conflict.
C. Saving clause and deemer clause
The Commissioner argued the saving clause (29 U.S.C. § 1144(b)(2)(A)) preserved the laws as insurance regulation, but the court held:
(i) the argument was forfeited (not addressed below), and (ii) in any event the deemer clause (29 U.S.C. § 1144(b)(2)(B)) would block
application to a self-funded ERISA plan. Citing FMC Corp. v. Holliday, the court emphasized that self-funded
ERISA plans cannot be “deemed” insurers for purposes of state insurance regulation—particularly where Tennessee’s statutory scheme
expressly swept ERISA plans into the PBM regulatory definitions.
3.3. Impact
1) Narrowing the post-Rutledge regulatory “green light”
The opinion is best read as a corrective to expansive interpretations of Rutledge v. PCMA. Rutledge is not a
blanket approval of PBM statutes touching ERISA plans; it tolerates certain price/cost regulations that do not dictate plan design.
Tennessee crossed the line by regulating (a) who must be in pharmacy networks and (b) how plans may structure participant cost-sharing
and incentives.
2) Pharmacy networks and tiering are treated as “central” ERISA plan administration
By repeatedly framing network composition and differential cost-sharing as “central” and “key benefit design,” the Sixth Circuit
signals that state laws reshaping preferred networks, limited networks, and steering incentives are particularly vulnerable to ERISA
preemption when applied to self-funded plans.
3) Enforcement mechanics matter for standing—and thus for pre-enforcement challenges
The court’s standing analysis underscores that complaint-driven administrative schemes (where “any member of the public” can initiate
proceedings) can generate a “credible threat” sufficient for pre-enforcement review, even absent warning letters or finalized sanctions.
That lowers procedural barriers for ERISA fiduciaries seeking early federal adjudication of preemption.
4) Drafting choices that expressly include ERISA plans can backfire
Tennessee’s explicit expansion of statutory definitions to include ERISA plans—and the “notwithstanding” clause applying the PBM part to
ERISA plans—made the ERISA collision unmistakable and strengthened the case for preemption, including via the deemer clause.
5) Practical consequences for states
States remain able to regulate PBMs in ways closer to Rutledge (e.g., reimbursement-rate methodology and pharmacy appeals processes),
but must tread carefully when regulation effectively mandates:
(i) open pharmacy networks, (ii) preferred-network access for any willing pharmacy, or (iii) uniform participant cost-sharing across
pharmacies—at least as applied to self-funded ERISA plans.
4. Complex Concepts Simplified
-
ERISA preemption (“relate to”): ERISA overrides state laws that “relate to” employee benefit plans. A law “relates to”
a plan if it has a forbidden reference to or connection with the plan. This case focuses on “connection with,” i.e.,
whether the law’s practical effect intrudes into plan design/administration.
-
“Connection with” tests (from Rutledge/Gobeille): A state law is likely preempted if it (a) mandates plan structure,
(b) binds administrators to particular benefit choices, (c) governs central plan administration, or (d) disrupts nationally uniform
plan administration.
-
Self-funded ERISA plan: The employer pays benefits from its own funds rather than buying an insurance policy to cover
claims. Self-funded status is crucial because the deemer clause prevents states from treating the plan as an insurer.
-
Any-Willing-Provider (AWP): A rule requiring a network to accept any provider (here, any licensed pharmacy) willing to
accept the network’s terms. Courts often view AWP mandates as altering network design and thus plan structure.
-
Cost-sharing / steering incentives: Copays, coinsurance, and differential pricing that encourage beneficiaries to use
certain pharmacies (e.g., preferred, mail-order, specialty, or plan-owned pharmacies). Tennessee’s “incentive provisions” effectively
forbid these differential tools within the network.
-
Saving clause vs. deemer clause: The saving clause can preserve state insurance regulation from ERISA preemption, but
the deemer clause prevents a state from treating a self-funded ERISA plan as an insurance company. In practice, many insurance-style
state rules still cannot be applied to self-funded plans.
-
Ex parte Young: A doctrine allowing suits against state officials (not the state itself) for prospective injunctions
to stop ongoing violations of federal law—here, enforcement of state statutes alleged to be preempted by ERISA.
5. Conclusion
McKee Foods Corp. v. BFP Inc. establishes a clear Sixth Circuit boundary for PBM-related state regulation applied to
self-funded ERISA plans: statutes that functionally mandate pharmacy network inclusion (AWP rules) or eliminate differential cost-sharing
and steering incentives intrude on core ERISA plan design and administration and are therefore preempted under ERISA’s “connection with”
doctrine as articulated in Rutledge v. PCMA and Gobeille v. Liberty Mut. Ins. Co..
The opinion’s broader significance is twofold. Substantively, it treats pharmacy network architecture and participant-facing cost-sharing
as central ERISA concerns, not mere economic side effects. Procedurally, it confirms that ERISA fiduciaries can bring pre-enforcement
challenges for equitable relief against state officials under an Ex parte Young framework, particularly where
administrative complaint mechanisms and affirmative enforcement positions create a credible threat of enforcement.
