What Does a Medical Expert Witness Do?
A medical expert witness is a licensed physician who reviews legal cases and provides professional opinions on clinical matters. Courts and attorneys rely on physicians to explain whether the care a patient received was appropriate, what caused an injury, what future treatment will cost, or whether a medical product caused harm.
This is not a patient-facing role. Your work product is written reports, phone consultations, depositions, and occasional courtroom testimony — nearly all of it from home or a home office. You review records, apply your clinical training, and communicate your findings clearly to non-medical audiences.
Most physicians start as a side income stream while still in practice, taking on a few cases per month. Some eventually build a full-time practice. Either approach works, and you set your own hourly rate.
Types of Cases You Can Work
| Case Type | What You Review | Common Specialties |
|---|---|---|
| Medical malpractice | Standard of care, causation, damages | All specialties |
| Personal injury | Injury severity, treatment needs, future care costs | EM, ortho, neurology, PM&R |
| Workers' compensation | Causation, disability ratings, return-to-work | Occupational medicine, ortho, EM |
| Product liability | Device or drug harm, labeling adequacy | Any relevant specialty |
| Life care planning | Future medical needs and costs | PM&R, neurology, any specialty |
How Expert Witnesses Get Paid
You set your own rates. Attorneys pay your hourly fee regardless of case outcome. Typical fee structures:
- Case review: $350–$700/hr to read records and form opinions
- Deposition: Often 1.5–2x your standard rate, plus a minimum block
- Trial testimony: Daily flat fee or premium hourly rate
