The federal law that requires a hospital emergency department to screen and stabilise anyone who comes through the door, regardless of insurance or ability to pay, before it may transfer or discharge them.
EMTALA is the reason an emergency department cannot turn a patient away for lack of insurance. Any hospital that participates in Medicare - which is nearly every hospital - must give anyone who comes to its emergency department asking for examination or treatment an appropriate medical screening examination to determine whether an emergency medical condition exists. If one does, or if a woman is in labour, the hospital must provide treatment to stabilise the condition within its capability, or transfer the patient to a facility that can, under conditions the statute sets: the patient must be stabilised to the extent possible, the receiving hospital must have agreed to accept them, and the transfer must be medically appropriate. A hospital may not delay the screening or stabilising treatment to ask about payment.
The duty is limited in ways that matter. It attaches at the emergency department and, once a patient is admitted as an inpatient in good faith, it generally ends and ordinary malpractice law takes over. It requires a screening comparable to what the hospital gives other patients with similar symptoms, not a correct diagnosis - a hospital that screens everyone equally badly may have committed malpractice without violating EMTALA. And it requires stabilisation, not cure: a patient who is stable may be discharged or transferred even if they are still unwell. Specialised hospitals with the capability to treat are required to accept appropriate transfers.
A patient harmed by a violation has a private right of action against the hospital (not against the individual physician) for the damages available under the state's personal-injury law, and the federal government may impose civil penalties on hospitals and physicians and exclude a hospital from Medicare. The statute also protects hospital staff who report a violation and prohibits a hospital from penalising a physician for refusing to transfer an unstable patient.
The signs of a violation are a screening that never happened, a transfer or discharge while the patient was visibly unstable, or a question about payment before treatment. A lawyer will look first at whether EMTALA applies at all - it is an emergency-department statute, not a general right to care - and then at whether the claim is better framed as malpractice, because the two have different defendants, different elements and different deadlines. A complaint to the state survey agency or the federal regional office is separate from any lawsuit and can be made by anyone.

Each link opens the directory page for the city in that state with the most currently published law firms in this practice area; a +n beside the city is how many other cities in the state also have one. The list is generated when this page loads, so a state whose listings have lapsed drops out rather than becoming a dead link.
