What Is an Independent Medical Examination (IME)?
Understanding the role of IMEs in litigation
IME Definition & Purpose
An Independent Medical Examination (IME) is a medical evaluation performed by a physician who has not previously treated the patient, specifically for legal or insurance purposes. The examiner provides an objective, unbiased opinion on medical issues relevant to a claim or lawsuit.
Key purposes:
- Establish or confirm medical diagnosis
- Determine causation of injuries
- Assess treatment appropriateness and necessity
- Evaluate maximum medical improvement (MMI)
- Calculate permanent impairment ratings
- Estimate future medical needs
- Determine work restrictions and disability
When Are IMEs Used?
Workers' Compensation Claims:
To determine compensability, MMI, permanent impairment, and work restrictions. Often requested by insurance carriers or employers.
Personal Injury Litigation:
Defense IMEs evaluate plaintiff's claimed injuries and treatment. Plaintiff attorneys may also retain independent experts to support their case.
Disability Claims (SSDI, LTD):
Insurance carriers use IMEs to assess disability claims and determine benefit eligibility.
Medical Malpractice:
Independent evaluation of whether care met standard of care and if alleged breach caused injury.
What Happens During an IME?
1. Records Review:
The IME physician thoroughly reviews all medical records, imaging studies, and relevant documentation before the examination.
2. Patient Interview:
Detailed history including onset of symptoms, treatments tried, current complaints, and functional limitations.
3. Physical Examination:
Comprehensive examination relevant to the claimed injury including range of motion, strength testing, neurological assessment, and special tests.
4. Report Preparation:
Detailed written report addressing specific questions posed, providing diagnoses, causation opinions, and conclusions supported by medical literature.
What Makes a Quality IME?

Defense vs. Plaintiff IMEs
Defense IME (Compulsory):
Typically ordered by defendants/carriers to evaluate plaintiff's claims. Patient must attend when properly noticed. Often challenges injury severity, causation, or treatment necessity.
Plaintiff IME (Retained Expert):
Plaintiff attorney retains expert to support case. Voluntary examination. May establish injury severity, support causation, validate treatment necessity, or provide impairment ratings.
