How do medical malpractice cases work in Arizona?

No cap on damages, and that changes everything

Start with the biggest difference. Many states, Texas most famously, cap the human damages in malpractice cases by statute. Arizona's constitution forbids laws limiting what can be recovered for injury or death, so an Arizona malpractice jury is allowed to award what the harm is actually worth: the lost years, the lifetime of care, the pain. That single fact is why a case that gets amputated by a cap elsewhere can be fully valued here.

The expert gate at the courthouse door

Arizona balances that openness with a demanding front door. Early in the case, with the first round of required disclosures, the injured patient must serve a sworn preliminary opinion from a qualified medical expert laying out the expert's qualifications, the facts, exactly what the provider did wrong, and how those failures caused the harm. This is not a formality; cases die here when the work is done casually.

The same-specialty rule

Arizona is strict about who counts as a qualified expert. The expert must practice in the same specialty as the defendant, and if the defendant is board certified in a specialty, the expert must be board certified in it too. The expert also must have spent most of the year before the events actually practicing or teaching in that specialty. Courts apply this granularly, down to sub-specialties, which is why finding the right expert, often from out of state, is a large part of the early investment in an Arizona malpractice case.

A bad outcome is not automatically malpractice

Medicine involves risk, and known complications happen without anyone being negligent. The legal question is whether the provider fell below the standard of care, the level of skill and judgment a reasonably careful provider in that specialty would have used, and whether that failure caused harm that better care would have avoided. Missed diagnoses, medication errors, surgical mistakes, ignored test results, and delayed treatment are the recurring patterns.

The clocks, and the public-hospital trap

The general window is two years, and it usually starts when the patient knew or reasonably should have known about the injury and its cause, which matters when harm surfaces slowly. But if the provider works for a public hospital or government entity, the timeline collapses: a formal notice of claim within 180 days and suit within one year. Children's claims run on different clocks. None of it is worth guessing about; malpractice cases need a lawyer's evaluation early, while records are fresh and the expert search can start.
