Is a bad outcome automatically malpractice?

No. Medicine involves risk even with excellent care. Malpractice requires showing the provider deviated from the accepted standard of care and that the deviation caused the harm.

Do I need an expert witness?

Almost always — most states require expert testimony, and often a pre-filing expert certificate, to even bring a malpractice claim.

Is there a cap on what I can recover?

Many states cap non-economic damages in malpractice cases specifically, though economic damages like medical costs and lost income are typically not capped.

How long do I have to file?

Malpractice claims often have a shorter or differently triggered deadline than regular injury claims — check your state's specific rule soon after discovering the harm.

How much does a malpractice case cost to bring?

Lawyers typically work on contingency, but malpractice cases require expensive expert witnesses upfront, which is part of why firms are selective about which cases they take.

Can I sue the hospital, or only the doctor?

Depending on the facts, both may be liable — hospitals can be responsible for their employees' negligence and sometimes for their own oversight failures.

Medical Malpractice

Legal information last reviewed: July 3, 2026

Medical malpractice is a specific and harder-to-prove type of negligence claim. A bad outcome alone isn't enough — you have to show the provider's care fell below the accepted standard of care and that the deviation actually caused your harm.

The standard of care

This means what a reasonably skilled provider in the same specialty would have done under similar circumstances. A bad outcome alone isn't malpractice if the provider still acted within accepted medical judgment.

Common types of claims

Misdiagnosis or delayed diagnosis, surgical errors, medication errors, birth injuries, and failure to obtain informed consent make up most malpractice claims.

Expert witnesses are almost always required

Nearly every state requires an expert in the same field to certify that a case has merit, often before or shortly after filing. Proving what a 'reasonable provider' would have done requires medical expertise a jury doesn't otherwise have.

Damages caps and special procedural rules

Many states cap non-economic damages, like pain and suffering, specifically in malpractice cases, and some require a pre-suit review panel before a case can even be filed in court — rules that don't apply to ordinary negligence claims.

Statute of limitations quirks

Malpractice claims often carry a shorter or differently triggered deadline than other injury claims. Some states use a 'discovery rule' that starts the clock when you reasonably should have discovered the harm, rather than when it actually happened.

When to hire a lawyer

Malpractice cases are expensive and technical to bring, so you need a lawyer from the start to evaluate whether the case is viable at all, not just to file it. Most malpractice attorneys offer a free initial case review for exactly this reason.
