Discover the 8 Most Common Types of Medical Malpractice Cases

February 23, 2026

Medical malpractice remains a serious concern in the United States, affecting thousands of patients and families every year. When healthcare providers fail to meet the accepted standard of care, the results can be devastating, leading to long-term injuries, permanent disability, or even wrongful death. Understanding the types of medical malpractice and types of medical negligence can help patients recognize when something may have gone wrong and when it may be time to speak with an experienced attorney.


Medical malpractice occurs when a doctor, nurse, hospital, or other healthcare professional acts negligently and causes harm to a patient. Not every bad medical outcome qualifies as malpractice. Instead, a case must involve a breach of the accepted medical standard of care that directly causes injury or damages.

Below are the eight most common types of medical malpractice cases seen across the United States.


1. Misdiagnosis


Misdiagnosis occurs when a healthcare provider identifies the wrong medical condition. This can result in unnecessary treatments, delayed proper care, or worsening of the actual illness.


For example, a patient experiencing symptoms of a heart attack may be misdiagnosed with acid reflux. If proper treatment is not provided promptly, the consequences can be severe or fatal. Similarly, diagnosing a benign condition when cancer is present may delay life-saving treatment.


Diagnostic errors are one of the leading types of medical negligence, largely because they can affect every stage of a patient’s care. Physicians are expected to carefully review symptoms, order appropriate tests, and interpret results accurately.


2. Delayed Diagnosis


Delayed diagnosis differs slightly from misdiagnosis. In these cases, the correct diagnosis is eventually made, but not soon enough to prevent harm.


Timely detection is critical for many medical conditions, including cancer, strokes, infections, and internal bleeding. When a doctor fails to order necessary tests, overlooks lab results, or ignores worsening symptoms, the delay may allow the condition to progress.


Even if the correct diagnosis is eventually given, the damage caused during the delay may form the basis of a malpractice claim.


3. Surgical Errors


Surgical errors are among the most well-known types of medical malpractice. While surgery always carries risks, some mistakes are preventable and may constitute negligence.


Examples of surgical errors include:


  • Operating on the wrong body part
  • Performing the wrong procedure
  • Leaving surgical instruments inside the patient
  • Damaging nearby organs or nerves
  • Failing to monitor the patient properly during surgery


Patients must be informed of known risks before surgery. However, when a surgical mistake occurs due to carelessness or failure to follow proper protocols, it may be considered malpractice.


4. Failure to Treat


Failure to treat happens when a medical professional correctly diagnoses a condition but fails to provide appropriate treatment.


This may include:


  • Discharging a patient too early
  • Not referring a patient to a specialist
  • Failing to schedule follow-up appointments
  • Ignoring abnormal test results


For instance, if a doctor diagnoses a serious infection but does not prescribe the necessary antibiotics, the patient’s condition could worsen significantly. Once a provider establishes a duty of care, they are responsible for ensuring the patient receives proper treatment.


5. Birth Injuries


Birth injury cases involve negligence during pregnancy, labor, or delivery. These cases can affect both the mother and the child and may result in lifelong medical challenges.


Common examples include:


  • Failure to monitor fetal distress
  • Delayed emergency C-section
  • Improper use of forceps or vacuum extraction
  • Oxygen deprivation during birth


Birth injuries may lead to conditions such as cerebral palsy, nerve damage, or developmental delays. Because these injuries can result in long-term medical expenses and emotional trauma, they are among the most complex and serious types of medical malpractice claims.


6. Medication and Prescription Errors


Medication errors are another common form of medical negligence. These errors can occur at multiple stages, including prescribing, dispensing, or administering medication.


Examples include:


  • Prescribing the wrong medication
  • Giving an incorrect dosage
  • Failing to check for drug interactions
  • Administering medication to the wrong patient


Medication errors can cause severe allergic reactions, organ damage, internal bleeding, or even death.


Healthcare providers are expected to carefully review a patient’s medical history and current medications to avoid preventable harm.


7. Anesthesia Errors


Anesthesia errors are particularly dangerous because even small mistakes can have life-threatening consequences.


Examples of anesthesia negligence include:


  • Administering too much or too little anesthesia
  • Failing to monitor vital signs
  • Not reviewing patient allergies or medical history
  • Improperly intubating a patient


Anesthesia errors may result in brain damage, oxygen deprivation, heart complications, or awareness during surgery. Due to the high level of skill required in administering anesthesia, professionals in this field are held to strict standards of care.


8. Failure to Prevent or Treat Infections


Hospitals and medical facilities must follow strict sanitation and infection control procedures. When they fail to do so, patients may develop serious infections.


Examples include:


  • Poor sterilization of surgical instruments
  • Failure to maintain clean environments
  • Not treating hospital-acquired infections promptly
  • Delayed response to signs of sepsis


Sepsis and other severe infections can quickly become life-threatening. If proper safety protocols were not followed, it may constitute one of the recognized types of medical malpractice.


What Must Be Proven in a Medical Malpractice Case?


To succeed in a medical malpractice claim, four key elements must generally be proven:


  1. Duty of Care – A provider-patient relationship existed.
  2. Breach of Standard of Care – The provider failed to meet accepted medical standards.
  3. Causation – The breach directly caused the injury.
  4. Damages – The patient suffered measurable harm, such as medical expenses, lost wages, or pain and suffering.


Medical malpractice cases often require expert testimony to establish whether the standard of care was violated.


Why These Cases Matter


Understanding the types of medical malpractice and types of medical negligence helps patients protect their rights. Medical professionals are entrusted with patient safety, and when preventable mistakes occur, victims deserve accountability and compensation.


Medical malpractice claims can provide financial recovery for:


  • Additional medical treatment
  • Rehabilitation and long-term care
  • Lost income
  • Pain and suffering
  • Wrongful death damages


Each state has specific laws and time limits (statutes of limitations) for filing malpractice claims. Acting quickly is essential to preserve evidence and protect your rights.
