Summary: written with AI from the case record.

What it's about
The Supreme Court agreed with the Fourth Circuit that federal Medicaid law bars that fixed presumption.
North Carolina had paid E.M.A.’s medical expenses through Medicaid and sought repayment from her injury settlement.
The dispute concerned how North Carolina could seek repayment of Medicaid expenses after a patient received money in an injury settlement.
Question presented
Does federal Medicaid law prohibit North Carolina's third-party liability statutes from mandating reimbursement of medical expenses from a patient's lump-sum settlement?
What the Court decided
Holding
The federal anti-lien provision pre-empts North Carolina’s irrebuttable statutory presumption that one-third of a tort recovery is attributable to medical expenses. 674 F. 3d 290, affirmed.
- Result
- Affirmed
The Court's reasoning
The Court said federal Medicaid law bars North Carolina’s rule because it automatically labeled one-third of an injury settlement as medical expenses without allowing that assumption to be challenged.
The vote
From the opinions
“The Court’s reading of the Act, while plausible, is not compelled by the statutory text or our precedent.”
What's next
The Fourth Circuit’s ruling remains in place, and North Carolina cannot use the automatic one-third presumption to set Medicaid repayment from injury settlements.
