What is a Medical Malpractice Expert Witness?

A medical malpractice expert witness is someone who has a specialized degree or qualifications that enable them to provide expert witness testimony that will be allowed into a deposition or courtroom as evidence. There are two main types of medical malpractice expert witnesses:


A medical expert witness is someone who has a medical degree and can testify one way or another in a malpractice deposition or lawsuit. Their experience as a licensed doctor gives them the ability to offer qualified opinions that can be accepted as evidence in a case.

A medical malpractice expert witness can range from a standard family doctor to a psychologist, to a specialist such as a heart surgeon. They all have a medical degree and usually years or even decades of experience. Sometimes, they will publish medical research papers to further bolster their credibility on a particular subject matter.


An expert economic witness in relation to medical malpractice deals with the economics of the injury or death. For example, they will be brought in to determine past and future loss of income or future life care expenses.

Or they can act as a medical claims auditor to assess the reasonableness of value of medical claims after the insurance companies and other parties negotiate the cost.

Economic expert witnesses are critical to medical malpractice and wrongful death cases. In addition to reviewing all court documents and performing a records review, they also consult various public and private records such as:

  • W2 Statements
  • Social Security Administration
  • Payroll Records
  • State Unemployment
  • Earnings History
  • Federal/State Tax Returns

Profit and loss calculations are also taken into consideration. Forensic economists will look at past and potential future earnings. Based upon the pre-incident records, we can determine how an individual or entity performed through today and provide a present value in today’s dollars on all of the loss of future cash flows to the individual.

Types of Medical Malpractice Claims

Medical malpractice claims that require a forensic economist can stem from one of several issues such as delayed diagnosis, wrong diagnosis, or even negligent delivery when it comes to newborn children.

Here are five types of medical malpractice claims and a brief explanation of each:

Medical Product Liability

Sometimes, a patient will suffer an injury as a result of a defective or poorly designed medical device. When such devices fail to work as advertised or become defective, severe injury or death can occur. For example, an IVC filter which helps prevent blood clots can break and cause serious injury or death.

Delayed Diagnosis

This is a form of medical malpractice and results when a doctor is negligent in diagnosing a medical condition. This delay in diagnosis can quickly turn into a delay of treatment and cause someone to lose life or limb.


A misdiagnosis occurs when the physician fails to diagnose the correct illness or condition the patient is suffering from. This, in turn, prevents the patient from receiving timely medical care, which could have resulted in injury, illness, or death.

Surgical Errors

Surgical errors can arise when the surgeon is negligent during a procedure. Such instances of medical instruments being left inside a body cavity, damaging unrelated organs, or performing the wrong procedure all constitute surgical errors.

Birth Injuries

Birth injuries or negligent deliveries are also considered medical negligence. The doctor or nurse could injure a newborn when it’s being born. Or, the doctor could be negligent in providing the baby immediate medical care for some condition that resulted from or during the birth.

Failure to Treat

A failure to treat occurs when a doctor arrives at the correct diagnosis but fails to treat the condition. For example, a doctor could release a patient too early, or before their condition has healed up. This is most often associated with hospitals and doctor’s offices that are overwhelmed with patients. The doctor could also be negligent in referring the patient to a specialist.

Why File a Medical  Malpractice Claim?

Medical malpractice cases arise when a party feels that the doctor or hospital did not provide a reasonable standard of care and that breach of duty caused them to sustain injuries. There are, however, a few things that people should take into consideration before filing a medical malpractice claim:

  • Was there a breach of duty?
  • Did the doctor fail to live up to their duty of care?
  • Was there an injury or death that was caused by the breach?
  • Do you have evidence to back up your claims?

If you’re considering filing a medical malpractice claim, ask your attorney about retaining the services of an expert forensic economic witness. They can help determine your loss of income and other economic damages you sustained as a result of your injury. This can also help bolster your case as well as ensure that your future medical expenses are taken into consideration when filing the claim.
