What Constitutes Medical Negligence?
What constitutes medical negligence in Florida is care that falls below the professional standard and then causes injury.

A difficult recovery does not, by itself, answer what constitutes medical negligence. Florida looks at two things. Did the care fall below what reasonably prudent, similar providers would accept in the circumstances? Did that departure cause the injury?
Under Florida Statutes section 766.102, what constitutes medical negligence is a breach of the prevailing professional standard of care. The breach must cause death or personal injury. It must be proved by the greater weight of the evidence. The existence of an injury does not create a presumption of negligence.

That question is narrower than a general complaint about a hospital stay. The pages below stay on the statutory test. The firm's personal injury practice is the broader service page, and its Fort Myers medical malpractice page is where a specific course of treatment can be reviewed.

What Constitutes Medical Negligence Under Florida Law
Section 766.102 covers medical negligence, standards of recovery, and expert witnesses.
In a damages claim for death or personal injury, the person bringing the claim has a defined burden. That person must prove, by the greater weight of the evidence, that the provider's actions breached the prevailing professional standard of care.
The statute defines that standard in practical terms. It is the level of care, skill, and treatment recognized as acceptable and appropriate by reasonably prudent similar health care providers. The statute judges that level in light of all relevant surrounding circumstances.
Two phrases do most of the work. "Greater weight of the evidence" means the claim must be more likely true than not. It is not a criminal proof standard. It is also not a guess based on how upsetting the outcome feels.
"Similar health care providers" means the comparison is to providers in a comparable role. The comparison is not to a perfect result. It is also not to a specialist who never would have been involved in that visit.
A poor outcome can be the reason a family starts asking questions. It is not the legal test. Care can meet the standard and still end badly, because illness and treatment both carry risk. Care can also look routine on a discharge summary and still fall short of what similar providers would have recognized as acceptable in those circumstances. The Kushner & Kushner Fort Myers medical malpractice page is the place to ask the firm to look at a specific course of treatment. This article only explains the test the statute uses.
| What a reader may assume | What section 766.102 actually asks |
|---|---|
| A bad outcome means the provider was negligent. | Whether the care, skill, and treatment fell below what reasonably prudent similar providers would recognize as acceptable in the circumstances. |
| Any physician can say what should have been done. | The comparison is to a similar health care provider, and the claimant must prove the breach by the greater weight of the evidence. |
| An injury that appeared after treatment is enough. | The injury must be tied to a breach of the prevailing professional standard of care, not merely to the fact that treatment happened. |
The statute also limits who may explain that standard in court. A person generally may not give expert testimony on it unless that person is a licensed health care provider who has reviewed the pertinent records. The witness must also meet the similarity rules for that kind of provider. That requirement is part of how Florida decides the standard. It is not a checklist for building a file at home.
A Medical Injury Does Not Prove Negligence by Itself
Section 766.102(3)(b) states the point directly. The existence of a medical injury does not create any inference or presumption of negligence against a health care provider. The claimant must still prove that the injury was proximately caused by a breach of the prevailing professional standard of care. In plain terms, the harm and the breach are separate facts. Both have to be shown.
Proximate cause is the link between the departure from the standard and the injury. A provider can depart from accepted care in a way that does not change the outcome. A patient can also be badly hurt by the illness itself while the care stayed within what similar providers would accept. Families often feel that second situation as a failure. The statute does not treat the feeling as proof.
There is a further limit when the claim is about an affirmative medical intervention. Examples include a surgery, a medicine, or a diagnostic procedure. If that intervention met the prevailing standard, one more showing is required. The claimant must show that the injury was not a necessary or reasonably foreseeable result of the procedure.
This point applies only when the intervention was undertaken with informed consent under section 766.103. A consent discussion is part of that statutory condition. A signed form is not, by itself, a complete answer to whether the care met the standard.
The same subsection keeps payment decisions out of the proof. Records, policies, or testimony about an insurer's reimbursement policies, or about what an insurer decided to pay, are not admissible to prove negligence. The statute's definition of insurer includes public and private insurers and the Centers for Medicare and Medicaid Services. A denial, a downcode, or a Medicare payment rule is not the prevailing professional standard of care.
When a Left-Behind Object Changes the Starting Point
Most medical negligence questions start with no presumption at all. Section 766.102 makes one narrow exception. Discovery of certain foreign bodies is prima facie evidence of negligence on the part of the health care provider. The statute lists a sponge, clamp, forceps, surgical needle, or similar paraphernalia commonly used in a surgical, examination, or diagnostic procedure.
Prima facie means the finding is enough to start the negligence showing. It is not a promise that the claim will succeed, and it does not skip the need to connect that object to the harm. It does mean a retained sponge or clamp is treated differently from a difficult diagnosis. The statute lists the kinds of objects that qualify. An unexpected complication, without an object left behind, does not fall under this sentence.
A second narrow rule runs the other way. Skipping a supplemental diagnostic test is not actionable in one situation. The provider must have acted in good faith and with due regard for the prevailing professional standard of care. Wanting one more scan after the fact is understandable. The statute asks what similar providers would have recognized as acceptable at the time. It does not ask whether a later result makes the extra test look wise.
Three checks keep those rules from being mixed together:
- Identify what was found, or what was not ordered, in the specific procedure or visit.
- Ask whether reasonably prudent similar providers would recognize that care as acceptable in light of the circumstances known at the time.
- Ask whether the injury is tied to that care, rather than to the illness or to a result the procedure can produce when the standard is met.
Filing deadlines and the presuit process are a different subject. The firm's Florida medical malpractice rights guide covers those steps separately.
Why Florida Often Uses Negligence and Malpractice for the Same Claim
Patients hear both labels, sometimes in the same conversation. Florida's presuit statute treats them as the same kind of claim. Section 766.106 uses both "claim for medical negligence" and "claim for medical malpractice" for the same idea. Each means a claim arising out of rendering medical care or services, or failing to render them. The wording is in section 766.106. This article does not walk through the notice process that section also describes.
Everyday carelessness is a useful English meaning, and it is not the legal test. Spilling coffee is not what section 766.102 measures. The statute measures care, skill, and treatment against a similar provider. The question is what that provider would recognize as acceptable and appropriate in the circumstances. A missed lab, a delayed reading, or a wrong dose matters only in a specific case. The comparison and a causal injury must be proved by the greater weight of the evidence.
Choosing a lawyer is a later question. A separate page explains how to look for a medical negligence attorney without repeating the statutory test. Related injury work sits on the firm's personal injury practice page. None of those pages decides whether a particular chart meets section 766.102. That depends on the records and on a qualified comparison to similar providers.

How to Read a Chart Against That Standard
The statute is easier to use if you separate the story into the facts it actually mentions. Start with who provided the care. Section 766.102 speaks to a health care provider. A hospital stay can involve several people, and the comparison is to a similar provider for the care at issue, not to every name on a bill.
Next, write down the circumstances that were known when the decision was made. The standard looks at all relevant surrounding circumstances. A later lab result can explain what the illness became. It does not, by itself, rewrite what a similar provider would have recognized as acceptable before that result existed.
Then separate the injury from the alleged breach. The statute keeps the burden on the person bringing the claim. An infection, a longer hospital stay, or a result the family did not expect is the harm to describe. It becomes part of a negligence question only if it was proximately caused by care that fell below the prevailing professional standard.
Four notes from the statute are worth keeping beside that timeline:
- A bad outcome is not an inference of negligence.
- A foreseeable result of a consented procedure, when the procedure met the standard, is treated differently from a breach.
- A left-behind sponge, clamp, forceps, surgical needle, or similar object is prima facie evidence of negligence.
- Not ordering a supplemental test is not actionable when the provider acted in good faith and with due regard for the standard.
Those notes still do not tell you whether a particular visit qualifies. Records, timing, and a comparison to similar providers do that work. Kushner & Kushner reviews Florida medical malpractice questions of this kind. The firm does not treat a difficult recovery as enough, and it does not promise an outcome from a first conversation.
Bring the questions the statute actually asks. Who treated you? What was known at the time? What injury followed? Was an object left behind, or was the concern a judgment about further testing? A free case evaluation is a way to put those facts in front of a lawyer. It is not a finding that the standard was breached.

Frequently Asked Questions
What constitutes medical negligence in Florida?
Florida Statutes section 766.102 requires proof by the greater weight of the evidence. A provider must have breached the prevailing professional standard of care. That breach must have caused death or personal injury. The standard is the care, skill, and treatment that reasonably prudent similar providers would recognize as acceptable in the circumstances.
Does a bad result count as medical negligence?
No. The statute says a medical injury does not create an inference or presumption of negligence. The injury still has to be tied to a breach of the prevailing professional standard of care.
Is a sponge left inside a patient treated differently?
Yes. Discovery of a foreign body such as a sponge, clamp, forceps, surgical needle, or similar paraphernalia used in a procedure is prima facie evidence of negligence. That starting point is specific to a left-behind object. It is not a rule for every complication.
Are medical negligence and medical malpractice different claims in Florida?
Section 766.106 uses both phrases for a claim arising out of rendering, or failing to render, medical care or services. The care is still measured under the section 766.102 standard.
Can an insurance payment decision prove the standard of care?
No. Section 766.102 says an insurer's reimbursement policies and reimbursement determinations are not admissible for that purpose. That includes Medicare and Medicaid payment decisions.
