Complete Medical Malpractice Lawsuit Guide

If a doctor, nurse or hospital made a mistake and you were hurt, you may be facing a new injury on top of the reason you went in, plus bills and missed work. Medical malpractice is when a health care provider fails to give the care a reasonably careful provider in the same field would have given, and that failure injures you. A bad outcome alone isn’t malpractice.

To win a malpractice lawsuit, you generally have to show what the right care was, how it fell short, that the shortfall caused your injury and what the injury cost you, usually with a medical expert’s help. Deadlines can be short, and some states, including Michigan, add steps before you can sue.

This guide covers the whole U.S. Michigan’s rules, current as of September 2026, are in the boxes marked “In Michigan.”

What counts as medical malpractice?

Malpractice is professional negligence: a professional’s failure to follow “generally accepted professional standards” (Legal Information Institute). In a medical case, you generally have to prove four things:

1. Duty. The provider was treating you, so it owed you professional care.
2. Breach. The care fell below the standard of care, explained below.
3. Causation. The breach caused your injury. Being hurt after a mistake isn’t enough; the mistake has to be the reason. See how causation is proven in injury cases.
4. Damages. You suffered real harm, such as more treatment, lost income, pain or a worse outcome.

If any one of these is missing, the claim fails.

What is the standard of care?

It’s what a reasonably careful provider with the same training would have done in the same situation. It isn’t perfection. A family doctor is measured against family doctors, and a specialist against the same specialty.

Why isn’t every bad outcome malpractice?

Medicine carries risks even when everything is done right. The U.S. Food and Drug Administration (FDA) gives an example: getting the wrong drug because two containers’ labels look alike is a preventable error, but a severe allergic reaction to a sulfa drug in someone with no history of allergies isn’t considered preventable.

The claims system mostly tells these apart. When physicians reviewed 1,452 closed malpractice claims, they found that 37% involved no medical error, and most of those (72%) weren’t paid. Most claims for injuries caused by an error (73%) were paid (New England Journal of Medicine, 2006).

What if you weren’t told about a risk?

Before most treatment, you’re generally entitled to know its significant risks and the alternatives. This is called informed consent, and a provider who clearly goes beyond what you agreed to can be liable (Legal Information Institute).

These claims have limits. A federal appeals court explained in 1972 that the undisclosed risk must actually happen and harm you, and that the missing warning caused your injury only if disclosure would have led a prudent person in your position to decide against the treatment (Canterbury v Spence, 1972).

What are the most common types of malpractice claims?

In a study of 350,706 paid malpractice claims reported to the federal National Practitioner Data Bank from 1986 to 2010, diagnostic errors were the most common type, at 28.6% of claims, and accounted for the largest share of payments, 35.2% (BMJ Quality & Safety, 2013).

A missed, wrong or delayed diagnosis

A diagnosis claim says a reasonably careful provider would have found the problem sooner, for example by ordering a test, following up on an abnormal result or referring you to a specialist, and that the delay made your outcome worse.

Diagnostic accuracy in emergency departments is high, but mistakes happen. A December 2022 review published by the federal Agency for Healthcare Research and Quality (AHRQ) estimated that about 1 in 18 emergency department patients get an incorrect diagnosis, or 7.4 million a year. Stroke, heart attack, aortic aneurysm and dissection, spinal cord injury and blood clots were the conditions most vulnerable to misdiagnosis. Peer-reviewed commentaries have criticized the review, so treat the figure as an estimate (AHRQ Patient Safety Network).

Many of these cases turn on one question: would you have done better if the problem had been caught in time? States differ when the chance of a better result was small to begin with. Massachusetts allows recovery for a lost chance even when it was less than 50% before the negligence (Matsuyama v Birnbaum, 2008). Michigan’s rule is stricter (see the box). For more, see how misdiagnosis claims work.

Surgical errors

Surgical claims can involve the operation itself, such as an injury to a nearby organ, or the care before and after it, such as missed signs of infection or bleeding. A known complication isn’t automatically malpractice. The questions are whether it happened because the care fell below the standard, or whether it was a significant risk you weren’t told about. Surgeons, other providers and the hospital can all be sued in the same case. See what to do after a surgical error.

Medication errors

Medication errors include the wrong drug or dose, a missed allergy or dangerous drug interaction, and a prescription filled incorrectly. Depending on where the mistake happened, the prescriber, the pharmacy, the hospital or a nursing home may be responsible. In Michigan, a licensed pharmacist is a licensed health care professional, but a pharmacy itself isn’t, so it “cannot be directly liable for medical malpractice”; a claim that a pharmacy let someone who isn’t a pharmacist fill prescriptions with no pharmacist on site is ordinary negligence, with a three-year deadline (Kuznar v Raksha Corp, 2008). A defective drug is a product liability claim against the maker (see below). See how medication error claims work.

Birth injuries

Birth injury claims ask whether problems during pregnancy, labor or delivery were recognized and handled in time, such as signs that the baby was in distress or needed a cesarean section. They can involve the mother, the baby or both. See how birth injury claims work and what to know about C-section errors.

Nursing home neglect

Nursing homes that take Medicare or Medicaid must meet federal requirements, which are also the basis for inspections (42 CFR 483.1), and Medicare’s Care Compare tool lets you compare homes’ quality of care and staffing. Falls, bedsores, medication mistakes and missed changes in a resident’s condition can all lead to claims. Some are malpractice and some are ordinary negligence, which can change the deadline. See nursing home neglect and elder abuse.

How is a malpractice lawsuit different from other injury claims?

Experts, extra steps and damage caps set these cases apart. Here’s how the main rules compare:

Other states have their own versions, so check with a lawyer licensed in your state.

Why do you need a medical expert?

In most malpractice cases, a qualified medical expert has to explain the standard of care, how it was broken and how that caused your injury. Each side usually hires its own experts, who are paid for their time (Legal Information Institute), so a lawyer will often have an expert review your records before filing anything.

What steps come before the lawsuit?

Each step has its own deadline and contents, and depends on your records and an expert’s review.

How long do you have to sue?

Every state sets a deadline to file, called a statute of limitations, and a malpractice deadline can be shorter than the one for other injuries. Some states also set an outer limit that can end a claim even if you didn’t know about it.

Are damages capped?

Some states, including Michigan and California, limit noneconomic damages in malpractice cases: money for pain, suffering and other harm with no price tag. In both, the cap doesn’t limit economic damages, such as medical bills and lost income.

Who can be held responsible?

• Individual providers, such as doctors, nurses, physician assistants, pharmacists and therapists.
• Hospitals, clinics and nursing homes. An employer is generally responsible for an employee’s wrongful acts on the job, but not for an independent contractor’s (Legal Information Institute), and a doctor who works at a hospital isn’t always its employee.
• The United States, if a VA health care employee treated you, or a federally funded community health center that the U.S. Department of Health and Human Services has “deemed” a Public Health Service employee (38 U.S.C. § 7316(a); 42 U.S.C. § 233(a), (g)). File a written claim with the agency within two years; you can sue only after it’s denied or six months pass without a decision, and once a denial is mailed, you generally have six months to sue (28 U.S.C. §§ 2401(b), 2675(a)).
• Drug and device makers, if the product itself was defective or lacked adequate warnings. Those are product liability claims, with different rules and deadlines. See how product liability claims work.

How do you get your medical records?

Your records are the backbone of a malpractice claim. The federal HIPAA Privacy Rule gives you the right to see and get a copy of your records from your providers and health plans (45 CFR 164.524):

• What’s covered: medical and billing records, test results, X-rays, consent forms and clinical notes, among others, but not psychotherapy notes kept separately (U.S. Department of Health and Human Services).
• How fast: within 30 days, or, once, up to 30 more days if the provider tells you in writing within the first 30 why and when (45 CFR 164.524(b)(2)).
• What it costs: only a reasonable, cost-based fee for copying labor, supplies and postage (45 CFR 164.524(c)(4)). A provider can’t refuse because you owe it for care (HHS).
• Format and delivery: an electronic copy if the records are electronic and you ask for one (45 CFR 164.524(c)(2)). On your signed written request, a provider must also send an electronic copy of your electronic health record straight to someone you choose; since a 2020 court order, that right covers only electronic health records, and the fee limit above doesn’t apply to it (45 CFR 164.524(c)(3); HHS).

Ask every provider involved in writing, and keep a copy of each request.

What can you recover in a malpractice case?

The money awarded for an injury is called damages:

• Economic damages: losses with a price tag, such as medical bills, future care, and lost wages or earning capacity.
• Noneconomic damages: harm without a receipt, such as pain, suffering, disability and disfigurement.

What a case is worth depends on the injury, the strength of the evidence, your state’s caps and any share of fault that’s yours. A payment to settle or satisfy a malpractice claim against a doctor, nurse or other practitioner must be reported to the federal National Practitioner Data Bank and the state licensing board, but a settlement doesn’t create a presumption that malpractice happened (45 CFR 60.7).

How much does a malpractice lawyer cost?

Injury lawyers often work on a contingency fee: a percentage of what’s recovered, and no fee if nothing is. Case costs are separate and can be high in malpractice cases, because experts, depositions and records all cost money. A lawyer can advance them and be repaid from the recovery; whether you owe them after a loss depends on your agreement and your state’s rules. See how personal injury lawyers get paid.

What if malpractice caused a death?

When a medical mistake causes a death, the family’s claim is usually a wrongful death claim. It follows the malpractice rules, plus rules on who files, who shares the money and how much time there is. See how wrongful death claims work.

What happens in a malpractice case, step by step?

1. Investigation. A medical expert reviews the records; a lawyer usually needs a supportive opinion to go further.
2. Notice, where required, and a waiting period.
3. Filing, with any required expert affidavit or certificate.
4. Discovery. Both sides exchange information and take depositions (sworn questioning before trial) of you, the providers and the experts.
5. Settlement talks or mediation, which can happen at any stage.
6. Trial, if the case doesn’t settle.

What to do next

1. Get the care you need now. If you’ve lost trust in a provider, you can ask for a referral or a second opinion. Keep every bill, and write down what happened, with dates and names.
2. Request your complete records from every provider involved.
3. Find your deadline. Malpractice deadlines can be short, and notice periods take months. In Michigan, see every Michigan injury deadline in one place.
4. Get a case review early, because an expert’s review takes time. Get a free case review, or if you’re in Michigan, compare Michigan injury lawyers. For a quick self-check first, see what to do if you think you have a malpractice case.
5. Get the fee agreement in writing, including how case costs are handled.

A complaint to your state’s licensing board can lead to discipline against the provider’s license, but it isn’t a claim for your losses and isn’t a step in a malpractice claim.

What waiting can cost

• The claim itself. A malpractice lawsuit filed after the deadline can be thrown out, however strong it is. In Michigan, a late malpractice action “is barred” (MCL 600.5838a(2)).
• Time for the steps before suing. A notice of intent needs your records and an expert’s review, and in Michigan it has to go out before the deadline passes to pause the clock (MCL 600.5856(c)).
• Evidence. Memories fade and staff move on.
• A family’s extra time. In Michigan, the estate’s extra time runs from the letters of authority and has an outer limit, so open the estate early (MCL 600.5852).

What a good outcome looks like

Your records are in hand, a qualified medical expert has reviewed what happened, and you know whether the care fell below the standard. If it did, the claim was filed on time with every required step, and the people responsible pay for your care, your lost income and what you went through, within your state’s limits. If it didn’t, you have a clear answer from someone qualified, and you can focus on getting well. From wondering whether what happened was malpractice to knowing what has to be proved, who can prove it and how long you have.
