Personal Injury IME in California: What Attorneys and Insurers Should Expect
A guide to independent medical evaluations in California personal injury cases -- from scheduling through report delivery.
Personal injury cases in California turn on medical evidence more often than attorneys want to admit. A liability case that looks solid going in can lose momentum when the medical opinions are contested, internally inconsistent, or inadequately documented. Conversely, a strong IME report in a case where liability is disputed can shift a settlement negotiation significantly.
This page explains what an IME in a California personal injury case covers, how the process works under CCP 2032, what the report should address, and what attorneys and claims professionals should watch for on both sides.
The Legal Framework: CCP Section 2032
In California civil litigation, the right to conduct a physical or mental examination of a party is governed by California Code of Civil Procedure section 2032. The key provisions:
- Who can be examined: any party whose physical or mental condition is in controversy. In a personal injury case, the plaintiff's physical condition is almost always in controversy.
- Notice requirement: the demanding party must serve a notice specifying the time, place, and identity and specialty of the examiner. If the plaintiff or their attorney objects to any of these, they may serve a written objection.
- Stipulation or court order: if the parties do not agree, the demanding party must obtain a court order. In practice, most examinations proceed by stipulation or after a brief meet-and-confer.
- Plaintiff's right to the report: upon request, the plaintiff is entitled to a copy of the report. If the plaintiff demands the report, the defendant loses the right to withhold the report from other parties.
- Scope: the examination is limited to the conditions in controversy. The examiner cannot expand the scope beyond what is relevant to the claimed injuries.
Note for defense counsel: The plaintiff has the right to have a representative present during the examination unless the examiner establishes a specific clinical reason they cannot be. Prepare your examiner for this possibility. An observer does not disqualify the examination, but it does mean the examination will be documented by someone other than the examiner.
Selecting the Right Examiner for a Personal Injury Case
Examiner selection in personal injury cases is often rushed. The case is moving, the examination deadline is approaching, and the attorney picks someone from a list without much analysis. This works until it does not, which is typically when the examiner is deposed.
The examiner should have board certification in the specialty most relevant to the primary claimed injury. They should have documented experience with medico-legal evaluations, not just clinical practice. For high-value cases, an examiner with substantial deposition and trial testimony experience is worth the additional cost.
Specialty matching matters. A cervical spine injury claim needs an orthopedic surgeon or a physical medicine and rehabilitation specialist, not an internist. A traumatic brain injury claim needs a neurologist or neuropsychologist. A psychological injury claim -- PTSD, adjustment disorder, depression secondary to injury -- needs a psychiatrist or licensed psychologist. Mismatching the examiner to the condition is a vulnerability that will be exploited.
What the IME Should Cover in a Personal Injury Case
Causation
The central question in most personal injury IMEs is whether the claimed injuries are causally related to the accident. This requires more than a clinical impression. The examiner must analyze the mechanism of injury, the biomechanical forces involved, the temporal relationship between the accident and symptom onset, the claimant's pre-existing conditions, and the medical literature on the injury type.
A vehicle traveling at low speed that rear-ends another vehicle presents a different biomechanical picture than a high-speed collision. The examiner should be able to explain the relevant physics, apply them to the claimed injuries, and address the treating physician's contrary causation opinion if one exists.
Nature and Extent of Injuries
The IME should address each claimed injury individually: whether it is supported by objective findings, whether the findings are consistent with the mechanism of injury, whether the severity of the claimed impairment is consistent with the objective evidence, and what the prognosis is.
Maximum Medical Improvement
Has the claimant reached the point where further treatment is not expected to produce meaningful functional improvement? If not, when is MMI expected? What treatment is reasonable and necessary to reach MMI? These questions directly affect damages calculations and settlement value.
Future Medical Care
Future medical care opinions are among the most financially significant in personal injury cases. An examiner who says the claimant needs a lumbar fusion, three years of physical therapy, and pain management for life has just added potentially hundreds of thousands of dollars to the damages calculation. An examiner who says MMI has been reached and no further treatment is indicated has taken it away. The opinion must be supported by findings, not just asserted.
Work Capacity
If the claimant alleges lost earnings or reduced earning capacity, the IME should address what they can and cannot do from a physical or psychiatric standpoint, and whether their claimed work restrictions are supported by objective findings.
Common Issues in California Personal Injury IMEs
Pre-Existing Conditions
California's pure comparative fault system does not bar recovery for aggravation of a pre-existing condition. But it does require the plaintiff to prove that the accident caused the aggravation, not just that the condition exists and the plaintiff was in an accident. The IME should address what was pre-existing, what changed after the accident, and how much of the current impairment is attributable to the accident versus the pre-existing condition.
Soft Tissue Injuries and Imaging
Many personal injury cases involve soft tissue injuries -- sprains, strains, muscle tears -- that are not visible on standard imaging. These cases are particularly contentious because the claimed symptoms may be severe but the objective evidence is limited to physical examination findings. The IME examiner's physical examination methodology becomes critical: documented, reproducible findings are far more defensible than a general impression of subjective pain reporting.
Gap in Treatment
Plaintiff attorneys know that gaps in treatment can be used against their clients at trial. Defense attorneys know it too. An IME examiner who notes a six-month gap in treatment and concludes that it suggests the claimant's symptoms resolved should be prepared to explain that reasoning against plaintiff's counsel's alternative explanation. A gap in treatment can reflect financial barriers, transportation issues, or a claimant's stoicism as easily as it reflects symptom resolution.
