If a doctor fails to make an accurate and timely diagnosis of a harmful medical condition, a patient might be able to pursue a legal remedy by filing a medical malpractice lawsuit. But it's important to keep in mind that mistakes and bad outcomes don't always mean medical negligence has occurred, at least not in the eyes of the law. (Learn more about when it's medical malpractice—and when it isn't.)
The key question in these kinds of cases is whether the health care provider breached the applicable "medical standard of care" under the circumstances. In other words, would a similarly-trained doctor in the same medical community have spotted the health problem (or identified it within a shorter period of time)? In the sections that follow, we’ll discuss some common misdiagnosis scenarios, and illustrate how this kind of medical malpractice claim might proceed.
While there are as many potential misdiagnosis scenarios as there are diseases and other health problems, some of the most common types of misdiagnosis are:
Typically a misdiagnosis case involves either a delayed diagnosis or mismanagement of diagnostic testing. Misdiagnosis may also involve:
When it comes to lawsuits over misdiagnosis, plaintiffs usually need to follow the same proof steps as in any other kind of medical malpractice case. It typically must be shown that, in failing to accurately diagnose a harmful health condition, the doctor failed to demonstrate the level of skill that a similarly-trained and experienced doctor would have shown under the circumstances. The treatment details—what should have been done, and what was actually done—must be laid out, usually by a qualified medical expert. It must also be shown that the doctor’s provision of sub-standard care led to harm to the patient.
In most cases, only the primary physician (your doctor) can be sued for misdiagnosis. In rare cases, other health care professionals may also be liable if their negligence caused or contributed to the patient’s harm—including nurses, lab techs, and any specialists who may have seen the patient. The hospital or health care facility where the doctor practices usually cannot be sued for harm caused by misdiagnosis. That’s because most doctors are independent contractors, not employees of the hospital, so the facility can’t be held legally responsible for the doctor’s negligence.
It’s not enough to show that the doctor failed to make the right diagnosis. A medical malpractice case will only be successful if it’s shown that the misdiagnosis resulted in harm to the patient. Misdiagnosis or delayed diagnosis may cause harm to the patient in a variety of ways, including:

Finally, in any medical malpractice case—in any type of lawsuit for that matter—plaintiffs need to be mindful of time limits for going to court and getting the lawsuit process started. You need to file the initial document (the complaint) within a certain amount of time after you suffered the harm that led to the lawsuit. These deadlines are set by state laws (statutes), so they’re called “statutes of limitations.” In some jurisdictions, the statute of limitations "clock" might not begin to run until the discovery of the injury, or until the patient had a reasonable opportunity to discover the injury. For example, in California, a patient has three years to file a medical malpractice lawsuit after the harm occurs, or one year after the harm is discovered, or should have been discovered (whichever comes first).
