A new rule issued by HHS under the Trump administration allows physicians, hospitals and insurers to refuse care to certain patients on grounds of religious beliefs—something a New York Times columnist says could lead to “chaos in healthcare.”

Editorialist Sandeep Jauhar, a cardiologist himself, said in the Times that the new rule—which would allow doctors to reject requests for abortions, assisted suicides and procedures for transgender patients—is a tricky one to navigate. While the American Medical Association’s code of ethics states physicians should “place patients’ welfare above their own self-interest,” that same code acknowledges “physicians should have considerable latitude to practice in accord with well-considered, deeply held beliefs that are central to their self-identifies.”

Jauhar said there are select cases where it’s universally acceptable to turn away patients, like if they’re being violent or intransigent. If a patient’s views don’t coincide with their doctor’s and that creates a problem, physicians should direct the patient to another provider whose beliefs better align with theirs.
