When a physician or provider may end a relationship with a patient, what notice and transition care they must give, and when ending it - or refusing to start it - becomes actionable.
A physician is generally free to decide whom to treat and may end a relationship with a patient for almost any reason - non-payment, a breakdown in trust, abusive conduct, the practice closing or the physician retiring - but not for a discriminatory reason and not in a way that leaves the patient without care at a critical time. Patient abandonment is the name for the second failure: unilaterally terminating the relationship, or failing to attend, without reasonable notice and without giving the patient an opportunity to arrange substitute care, while the patient still needs attention. It is a form of professional negligence, and in most states also a ground for licensing discipline.
What counts as reasonable depends on the patient's condition. Professional ethics rules and most licensing boards expect written notice, continued care for a stated interval while the patient finds another provider, emergency care during that interval, a copy or transfer of records, and help with a referral where the condition requires it; a patient mid-treatment, in the third trimester, on a medication that cannot safely stop, or in a specialty with few alternatives is owed more than a routine patient. A hospital or clinic that discharges a patient still requiring care, or a facility that transfers one for financial reasons, can be liable on the same principle, and hospitals owe emergency patients separate statutory duties.
Two things are not abandonment. A physician who never agreed to treat a person has no relationship to abandon - the duty arises only once one exists, which is why a refusal to accept a new patient is ordinarily lawful (subject to anti-discrimination law and, for emergency departments, the federal screening duty). And a patient who ends the relationship themselves, misses appointments or refuses the plan of care has not been abandoned, though a careful practice documents the patient's choice and the warnings given.
A patient dismissed from a practice should ask in writing for the notice period, interim emergency coverage and a records transfer, and should file a complaint with the state licensing board if none is offered; that route is free and is what the boards exist for. A lawsuit is worth discussing with a lawyer only when the gap in care caused a real injury, since abandonment is a malpractice claim with the same proof and cost as any other. A practice that needs to end a relationship should get its letter and interval right before sending it, because the board complaint is the more likely consequence of doing it badly.
