In Armstrong v. Exceptional Child Center, Inc., 575 U.S. 320 (2015), the Supreme Court held 5-4 that private Medicaid providers cannot sue state officials to enforce the reimbursement-rate requirements of the Medicaid Act. This case summary of Armstrong v. Exceptional Child Center walks through the dispute over Idaho’s payment rates, the Court’s rejection of a Supremacy Clause cause of action, and its conclusion that the Medicaid Act itself leaves enforcement to the federal executive branch.1Justia.

The Idaho Reimbursement Rate Dispute
Several residential care facilities in Idaho, including the Exceptional Child Center, sued the Idaho Department of Health and Welfare over Medicaid payment levels the state had kept unchanged for several years. The providers argued that the frozen rates violated Section 30(A) of the Medicaid Act, which requires state plans to set payments consistent with efficiency and economy, quality of care, sufficient beneficiary access to services, and safeguards against unnecessary use of services. They asked a federal court to enjoin state officials and force higher rates.1Justia. Armstrong v. Exceptional Child Center, Inc., 575 U.S. 320 (2015)
No Private Right to Sue Under the Supremacy Clause
The providers grounded their lawsuit in the Supremacy Clause of Article VI, arguing that the Constitution itself gives private parties an implied right to sue state officials whose actions conflict with federal law. Under that theory, no separate authorization from Congress would be needed.
The Court rejected the argument. Writing for the majority, Justice Antonin Scalia explained that the Supremacy Clause functions as a rule of decision: it tells courts which law controls when federal and state law conflict, but it does not, on its own, create a cause of action for private parties. Enforcing federal law against the states, the majority reasoned, generally belongs to the branches of government that write and administer those laws. The ruling closed off a route that private plaintiffs had used to challenge state administrative choices in federal court.1Justia. Armstrong v. Exceptional Child Center, Inc., 575 U.S. 320 (2015)
No Enforcement Right Under Section 30(A) of the Medicaid Act
The Court then considered whether the Medicaid Act itself let the providers sue. It held that Section 30(A) is not judicially enforceable by private parties. Deciding whether a given reimbursement rate is “consistent with efficiency, economy, and quality of care” calls for balancing complex financial and policy factors, work the Court viewed as better suited to administrative expertise than to judges.1Justia. Armstrong v. Exceptional Child Center, Inc., 575 U.S. 320 (2015)
The Act already provides a compliance mechanism. After reasonable notice and a hearing, the Secretary of Health and Human Services may withhold or limit federal payments to a state that fails to follow program requirements.2Office of the Law Revision Counsel. 42 U.S.C. § 1396c Because Congress built in that administrative remedy, the majority concluded, it did not intend for private lawsuits to enforce the same standards.1Justia. Armstrong v. Exceptional Child Center, Inc., 575 U.S. 320 (2015)
What the Decision Means for Providers
After Armstrong, providers who believe a state’s Medicaid rates fall short of federal standards cannot go directly to federal court for an injunction under either the Supremacy Clause or Section 30(A). Complaints about state compliance run instead through the Secretary of Health and Human Services, who holds the statutory tools to withhold federal funds. The ruling leaves the executive branch, not private plaintiffs, as the primary check on how states administer Medicaid reimbursement.
