A defense medical examination is a physical exam of an injured plaintiff performed by a doctor chosen and paid for by the defense, and in a California personal injury lawsuit it is one of the most important events between filing suit and trial. The doctor is not there to treat you. The purpose is to give the insurance company an expert opinion it can use to challenge your injuries, your need for treatment, and the value of your claim.
Many injured people first hear about the exam in a letter from the defense attorney and are unsure what it means. The exam usually arises during the discovery process in a personal injury case, when both sides gather evidence about the accident and the injuries. Understanding what happens, what the rules allow, and how to prepare helps you avoid mistakes that are hard to undo.
This guide explains who the examiner works for, the rights you have under California law, what to expect at the appointment, and how the report can affect your case.
What Is a Defense Medical Examination and How Is It Different From an IME?
You will often hear the same exam called a defense medical exam, a DME, or an independent medical examination (IME). The terms are used interchangeably, but “independent” can be misleading. The examiner is retained by the defense, usually has no prior relationship with you, and often performs these exams regularly for insurers.
- Who arranges it: the defendant or its insurance company, through defense counsel.
- Who the doctor works for: the defense. There is no doctor-patient treatment relationship.
- What it covers: the injuries claimed in the lawsuit, their cause, and the treatment you say you need.
- Why it is requested: to build a competing medical opinion to the one given by your own treating doctors.
Do You Have to Attend a Defense Medical Exam in California?
In most personal injury lawsuits, yes. When your physical condition is at issue, California discovery rules allow the defense to demand a physical examination, and the demand is not optional once it follows the proper procedure. Ignoring it can lead to a motion to compel and monetary sanctions. This is one reason it matters whether a case stays in negotiation or moves toward filing a lawsuit, since these exams are generally a lawsuit tool and not a claim-stage request.
Your obligation is to respond. Within 20 days of the demand, you must state in writing whether you will comply, comply with modifications, or refuse for specific reasons, and an attorney can object to a demand that goes beyond what the law permits.
What Rules Protect You During the Exam?
California Code of Civil Procedure sections 2032.220 and 2032.510, among others, set limits on these exams. The details can vary with the facts, so your attorney should review each demand, but the general protections include the following.
- One exam as a general rule: additional physical exams generally require an agreement or court permission for good cause.
- Written notice: the demand must state the time, place, manner, conditions, scope, and nature of the exam and identify the doctor, and the exam must be set at least 30 days after the demand is served.
- Reasonable location: the exam is generally limited to a location within 75 miles of your home.
- No painful or intrusive testing: the exam may not include diagnostic tests that are painful, protracted, or intrusive.
- Your attorney may attend: your lawyer or the lawyer’s representative is permitted to attend, observe, and record the exam, but may not participate or disrupt it, and can suspend it to seek a protective order if the examiner becomes abusive or attempts unauthorized tests.
- Mental or psychological exams: these are treated differently and require court permission and a showing of good cause.
What Happens at a Defense Medical Examination?
1. Check-In and Paperwork
You will be asked to arrive early, show identification, and complete intake forms. Do not sign anything that releases records or waives rights without having your attorney review it first.
2. The Medical History Interview
The doctor will ask about the accident, your symptoms, past injuries, prior accidents, work history, and daily activities. Answer truthfully and specifically, and describe how you feel on that day. Avoid guessing, exaggerating, or minimizing, because the examiner will compare your answers with the records.
3. The Physical Exam
The doctor will test range of motion, strength, reflexes, and areas of pain. These exams can be brief, and some last only a short time. If something is painful, say so clearly. Note what was done, how long it lasted, and anything unusual.
4. The Written Report
After the exam, the doctor prepares a report with opinions about diagnosis, causation, and future care. Your attorney can make a written demand for a copy of the detailed report, which generally must be delivered within 30 days of the demand along with any earlier reports on the same condition. The report then becomes part of the evidence in the lawsuit.
How Can the Report Affect Your Case?
Defense doctors commonly use the report to argue that an injury was pre-existing, that it has already resolved, or that treatment was unnecessary. They frequently point to gaps in medical treatment or to missing documentation, which is why consistent care and complete medical records that support your claim are so important.
The report also influences settlement. Insurers rely on it when negotiating, and it affects the factors that affect case value they are willing to accept. If the case proceeds in court, the doctor may be deposed and may testify, and your side can respond with expert witnesses in injury cases who explain why the defense opinion is wrong or incomplete.
How Should You Prepare for a Defense Medical Exam?
- Talk with your attorney first: review what the doctor is likely to ask and what the rules allow.
- Bring what you need: photo identification, a list of current medications, and a short list of your treating providers.
- Be consistent and honest: describe symptoms the way you have described them to your own doctors.
- Do not discuss fault or the lawsuit: the exam is about your medical condition.
- Be on time and polite: arrive early, but remember the appointment is part of the case.
- Assume you may be observed: act as you normally would in and around the building and avoid anything that contradicts your reported limitations.
