Petitioner-appellants, a group of pharmacies, health care providers, senior citizens’ groups, and Medi-Cal beneficiaries (collectively “ILC”), 1 seek to enjoin a state official from implementing legislation reducing payments to medical service providers under the state’s Medicaid program, known as “Medi-Cal,” by ten percent. ILC alleged in its complaint that the state legislation violates certain provisions of the federal Medicaid Act, and is therefore preempted under the Supremacy Clause. 2 Although ILC sought preliminary relief, the district court denied any such relief, holding that ILC could not allege any viable claim for injunctive relief because none of the petitioners or their members have any federal right to Medi-Cal payments or benefits. We do not agree that this suit fails for this threshold reason, and therefore reverse.
I.
A.
Under Title XIX of the Social Security Act, 42 U.S.C. § 1396
et seq.
(the “Medicaid Act”), the federal government provides funds to participating states to “enabl[e] each State, as far as practicable ... to furnish [ ] medical assistance on behalf of families with dependent children and of aged, blind, or disabled individuals, whose income and resources are insufficient to meet the costs of necessary medical services[.]” 42 U.S.C. § 1396. Medicaid is a cooperative federal-state program, enacted by Congress pursuant to its powers under the Spending Clause,
see
U.S. Const, art. 1, § 8, cl. 1, that “ ‘directs federal funding to states to assist them in providing medical assistance to low-income individuals.’ ”
Ball v. Rodgers,
Under that provision, § 1396a(a)(30)(A) (“Section 30(A)”), a state plan must:
*1053 provide such methods and procedures relating to ... the payment for[ ] care and services ... as may be necessary ... to assure that payments are consistent with efficiency, economy, and quality of care and are sufficient to enlist enough providers so that care and services are available under the plan at least to the extent that such care and services are available to the general population in the geographic area[.]
That is, a state plan must establish reimbursement rates for health care providers that are both consistent with high-quality medical care (the “quality of care provision”) and sufficient to enlist enough providers to ensure that medical services are generally available to Medicaid recipients (the “access to care provision”).
See generally Orthopaedic Hosp. v. Belshe,
B.
California Assembly Bill X35 (“AB 5”), enacted on February 16, 2008, during a special session convened by the Governor to address the state’s budget deficit, reduces payments to medical providers participating in the state’s Medi-Cal program by ten percent. Section 14 of AB 5 instructs the Director of the Department of Health Care Services, the state agency responsible for administering the MediCal program, to reduce payments to physicians, dentists, pharmacies, adult day health care centers, clinics, health systems and other providers participating in Medical’s fee-for-service program by ten percent. See Cal. Welf. & Inst. Code § 14105.19 (2008). Section 14 also reduces payments to managed health care plans under contract with the Department by the “actuarial equivalent” of ten percent. Id. Section 15 of AB 5 instructs the Director to reduce payments for inpatient services provided by acute care hospitals not under contract with the Department by ten percent. See id. § 14166.245. All of these cuts were scheduled to tafee effect July 1, 2008.
ILC filed this suit in California state court seeking to enjoin implementation of AB 5 on April 22, 2008, maintaining that the ten-percent rate reduction violates both the “quality of care” and “access to care” provisions of § 30(A) and is therefore invalid under the federal Constitution’s Supremacy Clause, as it conflicts with governing federal law. The complaint alleged that even prior to passage of AB 5, a substantial percentage of medical care providers — 45% of primary care providers and 50% of specialists — were unwilling to participate in the Medi-Cal program due to low reimbursement rates; that 90% of dentists refused to accept Medi-Cal patients; and that Medi-Cal’s reimbursement rates for prescription drugs allowed pharmacies to “uniformly earn less than a 10% net profit.” By further reducing already-low reimbursement rates, ILC argued, AB 5 would drive even more primary care physicians, specialists, dentists, and pharmacies out of the Medi-Cal program and force existing providers to reduce services. As a result, ILC contended, MediCal recipients would be “denied quality medical services and access to quality medical services,” in violation of § 30(A). ILC also maintained that nothing in the legislative history of AB 5 demonstrated that the legislature had considered whether reduced payments would be consistent with efficiency, economy, and quality of care, or whether such payments would be sufficient to enlist an adequate network of health care providers. Rather, the sole purpose cited in the legislation was to “address[] the fiscal emergency declared by the Governor” and “implement cost containment measures affecting health services, at the earliest possible time.” ILC therefore requested a peremptory writ of mandate or injunction to prevent the De *1054 partment of Health Care Services 3 and its Director, Sandra Shewry (“the Director”), from implementing AB 5. 4
C.
The state defendants removed the suit to federal court, where ILC filed a motion for preliminary injunction. The district court denied relief, holding that although it was “acutely cognizant of the potential adverse consequences of the ten percent rate reduction,” ILC had “no likelihood of succeeding on the merits” because they “do not have any federal rights under § 30(A).”
In reaching this conclusion, the district court relied heavily on this court’s decision in
Sanchez v. Johnson,
which held that § 30(A) does not “create an individual right that either Medicaid recipients or providers would be able to enforce under [42 U.S.C.] § 1983.”
In so ruling, the district court rebuffed ILC’s argument that it was entitled to seek purely injunctive relief — which is all it is seeking — on the basis of federal preemption under the doctrine recognized in
Shaw v. Delta Air Lines, Inc.,
ILC immediately sought emergency relief in this court. We granted ILC’s motion to expedite oral argument, but denied the balance of its emergency motion. We heard argument on July 11, 2008, and issued an order the same day reversing the district court’s decision and remanding for consideration of the merits of ILC’s mo *1055 tion for preliminary injunction. 5 This opinion more fully sets forth the rationale for our July 11 order.
II.
We review a district court’s denial of a preliminary injunction for abuse of discretion.
The Lands Council v. McNair,
In this case, the district court denied ILC’s motion for a preliminary injunction based solely on its legal ruling that ILC could not bring suit under the Shaw Supremacy Clause doctrine. The only issue before this court is thus whether ILC may maintain a valid cause of action to enjoin implementation of AB 5 on the basis of federal preemption.
A.
The Supreme Court has repeatedly entertained claims for injunctive relief based on federal preemption, without requiring that the standards for bringing suit under § 1983 be met, and without intimating that such claims must fit into one of three categories or “circumstances” in order to be cognizable. In
City of Burbank v. Lockheed Air Terminal, Inc.,
In
Ray v. Atlantic Richfield Co.,
Perhaps the most well-known in this line of cases is
Shaw v. Delta Air Lines, Inc. Shaw
involved the claims of several large employers, who brought suit against the Acting Commissioner of the New York State Division of Human Rights, arguing that the State’s Human Rights and Disability Benefits Laws — which required employers to treat pregnancy no differently than any other non-occupational disability — were preempted by the federal Employee Retirement Income Security Act (“ERISA”).
It is beyond dispute that federal courts have jurisdiction over suits to enjoin state officials from interfering with federal rights.[ 8 ] A plaintiff who seeks in- *1057 junctive relief from state regulation, on the ground that such regulation is preempted by a federal statute which, by virtue of the Supremacy Clause of the Constitution, must prevail, thus presents a federal question which the federal courts have jurisdiction under 28 U.S.C. § 1331 to resolve.
Id.
(internal citations omitted). The Court concluded by noting that it “frequently has resolved pre-emption disputes in a similar jurisdictional posture,” citing,
inter alia, Ray
and
Florida Lime & Avocado Growers. Id.
Thus,
Shaw
did not give rise to some unique line of
“Shaw
preemption” cases, but merely reaffirmed the traditional rule that injunctive relief is presumptively available in federal court to enjoin state officers from implementing a law allegedly preempted under the Supremacy Clause.
9
See Lawrence County v. Lead-Deadwood Sch. Dist. No. 40-1,
B.
Contrary to the district court’s conclusion that
“Shaw
preemption claims” have been permitted in only three “circumstances,” we know of no authority limiting
Shaw
in this manner, nor has the Director cited any. In fact, the Supreme Court recently reaffirmed
Shaw’s
holding, maintaining that it had “no doubt” as to the authority of private parties to seek injunc-tive relief on the basis of federal preemption under 28 U.S.C. § 1331 and the Supremacy Clause.
See Verizon Md. Inc. v. Pub. Serv. Comm’n,
Nor are we certain on what grounds the district court concluded that ILC lacked a valid cause of action in this case. The first two of the district court’s three “circumstances” — whether the challenged statute “restricts” or “compels” petitioners’ own conduct — appear to reflect traditional standing doctrine, which requires a litigant to “demonstrate that it has suffered a concrete and particularized injury that is either actual or imminent, that the injury is fairly traceable to the defendant, and that it is likely that a favorable decision will redress that injury.”
Massachusetts v. E.P.A.,
*1058 The parties have proceeded on the assumption that the district court denied relief because ILC lacked any judicially enforceable “rights” under the federal statute. 10 The Director specifically urges this court to deny ILC relief “because [§ 30(A) ] does not confer a private right of enforcement upon petitioners, which is the necessary predicate to seeking relief under the Supremacy Clause.” Were we to accept it, this argument would work a fundamental change in Supremacy Clause jurisprudence. We decline to do so, and thus join several other circuits in holding that a plaintiff seeking injunctive relief under the Supremacy Clause on the basis of federal preemption need not assert a federally created “right,” in the sense that term has been recently used in suits brought under § 1983, but need only satisfy traditional standing requirements.
1.
Although the Director asserts that the express conferral of a “private right of enforcement” on petitioners is a “necessary predicate” to a claim for injunctive relief under the Supremacy Clause, the well-established rule in both this court and in other circuits is precisely the opposite. In
Bud Antle, Inc. v. Barbosa,
Our holding in Bud Antle is consistent with established practice in the other circuits, which have universally affirmed the right of private parties to seek injunctive relief under the Supremacy Clause regardless of whether the allegedly preemptive statute confers any federal “right” or cause of action. As the Tenth Circuit explained,
*1059 A federal statutory right or right of action is not required where a party seeks to enjoin the enforcement of a regulation on the grounds that the local ordinance is preempted by federal law. A party may bring a claim under the Supremacy Clause that a local enactment is preempted even if the federal law at issue does not create a private right of action.
Qwest Corp. v. City of Santa Fe,
2.
The Director acknowledges these general principles but argues for a different result in this case, based on the specific statutory provision at issue. The Director provides little, if any, justification for treating a claim of preemption under a federal statute passed pursuant to Congress’s spending power differently from a claim of preemption under any of the federal statutes discussed above. But even if she had, this argument has also been flatly rejected by the Supreme Court and the other circuits that have addressed the question.
In
Pharmaceutical Research & Manufacturers of America (“PhRMA’’) v. Concannon,
We know of no governing authority to the effect that the federal statutory provision which allegedly preempts enforcement of local legislation by conflict must confer a right on the party that argues in favor of preemption. On the contrary, a state or territorial law can be unenforceable as preempted by federal law even when the federal law secures no individual substantive rights for the party arguing preemption.
Id.
(quoting
St. Thomas
— St.
John Hotel & Tourism Ass’n,
Although the First Circuit permitted PhRMA to bring suit, the court ultimately held that Maine’s statute was not preempted by federal law because there was no conflict between its requirements and those of the Medicaid Act.
See id.
at 74-79. PhRMA successfully petitioned the Supreme Court for certiorari, and the state defendants renewed their claim that PhRMA lacked any federal right to bring suit. Like the Director in our case, defendants argued that “[the Supremacy Clause] does not, by its own force, protect or regulate any interests,” and that PhRMA must therefore “look to the allegedly preempting federal statute to find an interest to support standing.” Brief for Respondents at 13-17,
PhRMA v. Walsh,
Not acceding to the defendants’ argument that PhRMA lacked a cause of action under the Supremacy Clause, seven Justices reached the merits of PhRMA’s claim for injunctive relief.
See PhRMA v. Walsh,
Although the Supreme Court’s decision in
Walsh
affirmed PhRMA’s ability to bring suit under the Supremacy Clause
sub silentio,
two circuits have expressly relied on
Walsh
to permit suits for injunc-tive relief. In
PhRMA v. Thompson,
In
Planned Parenthood of Houston v. Sanchez,
In assessing plaintiffs claims for injunc-tive relief, the Fifth Circuit began by noting that “[i]t is well-established that the federal courts have jurisdiction under 28 U.S.C. § 1331 over a preemption claim seeking injunctive and declaratory relief.” Id. at 331 (citing Shaw). The court then cited Walsh and Thompson for the principle that “asserting the preemptive force of federal Spending Clause legislation” itself states a claim for relief, even if “[Planned Parenthood was] not seeking to vindicate any right or to enforce any duty running to them.” Id. at 331-32. After a thorough canvassing of preemption cases, see id. at 331-34 & nn. 25, 27-28, 37, 46-47, the court had “little difficulty ... holding that[Planned Parenthood had] an implied right of action to assert a preemption claim seeking injunctive and declaratory relief.” Id. at 335.
We find the reasoning of the D.C. and Fifth Circuits persuasive. 14 For more *1062 than a century, federal courts have entertained suits seeking to enjoin state officials from implementing state legislation allegedly preempted by federal law, and we see no reason to depart from the general rule in this case, or in this category of cases. We therefore join several other circuits in holding that a party may seek injunctive relief under the Supremacy Clause regardless of whether the federal statute at issue confers any substantive rights on would-be plaintiffs.
3.
The reasoning adopted by the other circuits is also helpful in identifying the fundamental flaw with the Director’s position. By maintaining that ILC cannot proceed unless it can demonstrate that AB 5 interferes with some federally created right, the Director essentially asks us to apply the test for determining whether a plaintiff may seek relief under 42 U.S.C. § 1983, which provides a remedy for “the deprivation of any rights, privileges, or immunities secured by the Constitution and laws.”
15
The Supreme Court has interpreted the text of § 1983 to require a plaintiff to show the deprivation of “an unambiguously conferred right” in order to support a cause of action brought under § 1983.
Gonzaga Univ. v. Doe,
The Eighth Circuit’s decision in
Lankford v. Sherman,
The Fifth Circuit reached a similar conclusion in
Planned Parenthood v. Sanchez.
As noted above, plaintiffs sought to enjoin implementation of Texas’s Rider 8, which required recipients of federal funds to cut all ties with any organization performing elective abortions.
Sanchez,
Appellees are not asking the courts to enforce their “right” under § 1983 to secure enforcement of [the Public Health Safety Act], as TDH asserts. Rather, Appellees’ Supremacy Clause argument is fundamentally different: they argue that Rider 8 imposes conditions on the receipt of federal funds that are incompatible with [the Act], Therefore, we need not be concerned that the Supremacy Clause does not of its own force create rights enforceable under § 1983.
Id.
The court then noted that
“Gonzaga,
by its terms, applies only to § 1983 claims.... The Supremacy Clause claim advanced here ... is not based on a claim of right under [the Act], nor is it a claim for damages; it is a preemption claim. The
Gonzaga
Court gave no indication that it intended to alter its prior practice regarding such claims.”
Id.
The court therefore concluded that a claim of preemption under the Supremacy Clause “does not require a showing, as per
Gonzaga,
that a § 1983 action would also be proper.”
Id.; see also Local Union No. 12004,
For the reasons identified by the Fifth Circuit in
Planned Parenthood v. Sanchez,
the Director’s heavy reliance on our decision in
Sanchez v. Johnson,
Indeed, even as the Supreme Court has tightened the requirements for seeking damages under § 1983, it has consistently reaffirmed the availability of injunctive relief to prevent state officials from implementing state legislation allegedly preempted by federal law. In
Green v. Mansour,
The Court denied relief, holding that plaintiffs’ requests for notice and declaratory relief constituted claims for retrospective damages and were thus barred by state sovereign immunity under the Eleventh Amendment.
Id.
at 71-74,
The Director’s arguments fail to honor this distinction, broadly asserting instead that because § 30(A) of the Medicaid Act does not confer any substantive “rights,” ILC is not entitled to relief of any kind, whether prospective or retrospective.
Green
cautioned against conflating claims for prospective and retrospective relief in precisely this manner, recognizing that a state’s interest in continuing to flout binding federal law is illegitimate.
C.
Because it held that ILC could not bring suit under the Supremacy Clause, the district court did not technically reach petitioners’ standing to bring suit. As noted above, however, the first and second prongs of the district court’s
Shaw
analysis — which focused on whether AB 5 “restricts” or “compels” petitioners’ conduct — appear to reflect the traditional requirement that a litigant demonstrate an injury-in-fact to establish Article III standing.
See Lujan v. Defenders of Wildlife,
To satisfy Article III standing requirements, a plaintiff must demonstrate three elements:
First, the plaintiff must have suffered an injury in fact-an invasion of a legally protected interest which is (a) concrete and particularized; and (b) actual or imminent, not conjectural or hypothetical. Second, there must be a causal connection between the injury and the conduct complained of-the injury has to be fairly traceable to the challenged action of the defendant, and not the result of the independent action of some third party not before the court. Third, it must be likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision.
Lujan,
Petitioners include independent pharmacies and health care providers participating in the State’s Medi-Cal program that, according to their complaint, will be “directly injured, by loss of gross income,” when the ten-percent rate reduction takes effect. The Supreme Court “repeatedly has recognized that such [direct economic] injuries establish the threshold requirements” of Article III standing.
Craig v. Boren,
Petitioners also include several individual Medi-Cal beneficiaries, who “will be injured or put at risk of injury by implementation of the 10% provider payments cuts” because those cuts will reduce “quality services, and access to quality services.” This injury, like the injury to medical providers discussed above, is the direct result of the Director’s implementation of AB 5, and would certainly be remedied by a decision granting injunctive relief. Such an injury “to those individuals most directly affected by the administration of[a state welfare] program” is sufficient to allow petitioners to seek injunctive relief in federal court.
Rosado v. Wyman,
Conclusion
Under well-established law of the Supreme Court, this court, and the other circuits, a private party may bring suit under the Supremacy Clause to enjoin implementation of state legislation allegedly preempted by federal law. In this case, ILC alleges that the cuts mandated by AB 5 violate the substantive provisions of the federal Medicaid Act, and are therefore *1066 unlawful. They do not seek to enforce any substantive “right” conferred by statute; instead, they argue that the cuts mandated by AB 5 are themselves unenforceable, because they exceed the scope of the State’s discretion under the Act and violate federal standards. As AB 5 is causing injury to one or more of the plaintiffs and the other requirements of Article III standing are met, no more is required to allow this suit to go forward.
We express no opinion on the merits of ILC’s preemption claim. Rather, we simply reaffirm over a century’s worth of precedent and hold that ILC maintains a valid cause of action under the Supremacy Clause to assert such a claim for injunctive relief. The district court’s opinion is therefore REVERSED and REMANDED for further proceedings consistent with this opinion.

Independent Living Center, the Gray Panthers, and the pharmacy petitioners also sued to assert the interests of their respective patients and members. We refer to petitioner-appellants collectively as ''petitioners," “Independent Living Center,” or "ILC.”

See
29 U.S.C. § 1132(a). The same provision, however, is silent as to employers, and has generally been interpreted to mean that an employer cannot maintain an action directly under ERISA.
See, e.g., DeMarco v. C & L Masonry, Inc.,
.

utilized the term "federal rights,” it did so before that term had taken on the added significance attributed to it in more recent cases such as

. Indeed,
Shaw
itself traced the roots of the doctrine to
Ex parte Young,
. As noted above, the district court also concluded that the Supremacy Clause itself does not give rise to any federal "right” to legal relief. In reaching this conclusion, however, the district court relied on a series of cases holding that the Supremacy Clause does not give rise to rights
enforceable under § 1983,
an altogether separate remedial scheme.
See Golden State Transit Corp.,
. To ensure pharmaceutical companies’ participation in the program, the statute subjected all drugs produced by manufacturers refusing to offer rebates to "prior authorization requirements," meaning that the drug could not be prescribed to a- Medicaid beneficiary unless the state Medicaid administrator specifically approved the prescription. See id. at 71-72.
. Justices Scalia would have held that PhRMA could not bring suit, because “the remedy for the State’s failure to comply with the obligations it has agreed to undertake under the Medicaid Act is set forth in the Act itself: termination of funding.”
See id.
at 675,
. Texas accepted federal funds for family planning services by voluntarily participating in a number of federal programs, including the Public Health Services Act and the Social Security Act. Id. at 327.
. The district court stated that ILC's reliance on
Concannon
was misplaced because plaintiffs in that case had "established a concrete injury in fact” — standing language, as we shall see — -whereas “[h]ere, § 30(A) does not give petitioners any right to Medi-Cal funds.” In fact,
Concannon
expressly permitted PhRMA to bring suit for injunctive relief in the absence of any statutory right to Medicaid funds.
See
Similarly, there is no viable distinction for present purposes between the restrictions on *1062 planned Parenthood’s activities imposed by the statute at issue in Planned Parenthood v. Sanchez and the impact of AB 5 on the MediCal providers in this case. AB 5 allegedly prevents petitioners from providing services to Medi-Cal beneficiaries unless they are willing to do so at a financial loss, and thus assuredly "restricts” petitioners' provision of professional services.
. Section 1983 provides: "Every person who, under color of any statute, ordinance, regulation, custom, or usage, of any State, ... subjects, or causes to be subjected, any citizen of the United States or other person within the jurisdiction thereof to the deprivation of any rights, privileges, or immunities secured by the Constitution and laws, shall be liable to the party injured in an action at law, suit in equity, or other proper proceeding for redress....” 42 U.S.C. § 1983.
. Although the Director does not contest petitioners’ standing, she does argue that the interests protected by § 30(A) are not judicially enforceable because § 30(A) concerns “overall methodology” and “merely requires states to consider various factors in setting reimbursement rates.” We express no opinion regarding the correct interpretation of the substantive provisions of § 30(A), as such arguments are properly addressed to the merits of petitioners’ preemption claim.
See Wilder
v.
Va. Hosp. Ass’n,

See Bd. of Natural Res. v. Brown, 992
