Do I need a doctor’s testimony to prove my injury was caused by the accident?

· 3 min read

It depends on how obvious the connection is. For straightforward injuries with a plain link to the event, lay evidence may be enough. But where the cause of a medical condition is not something an ordinary person can judge, Georgia generally requires expert medical testimony to establish that the accident caused the injury.

When medical causation needs an expert

Georgia draws a line between injuries whose cause is within common understanding and those that are not. A visible cut, a broken bone clearly tied to a crash, or bruising that appears right after impact may be provable through the injured person’s own account, photographs, and treatment records, because a jury can connect the event and the harm without specialized knowledge.

The picture changes for conditions where the causal link is medically complex. Internal injuries, aggravation of a degenerative condition, soft-tissue problems, or symptoms that emerge over time often fall outside everyday experience. In those situations Georgia treats causation as a matter requiring expert opinion, because deciding whether the accident, rather than some other factor, produced the condition calls for medical training. Without a qualified opinion connecting the event to the diagnosis, a jury would be left to speculate, which the law does not allow.

What the medical opinion must address

When expert testimony is required, the opinion generally must do more than confirm that an injury exists. It typically needs to link the specific accident to the specific harm. Useful medical testimony usually:

  • States that the accident caused or aggravated the condition, expressed to a reasonable degree of medical certainty rather than as mere possibility.
  • Explains the basis for that opinion, such as the mechanism of injury, the timing of symptoms, and the treatment history.
  • Addresses other potential causes, including any prior condition, so the jury can see why the accident is the likely source.

A physician who treated the injured person is often well positioned to give this testimony, though a retained expert may also do so. The key is that the opinion ties the diagnosis to the event in a way grounded in the records and sound methodology, not conjecture.

The admissibility of any expert opinion in a Georgia civil case is governed by O.C.G.A. § 24-7-702, which requires the testimony to be both reliable and relevant before a jury hears it.

The bottom line

A doctor’s testimony is not always necessary in Georgia, but it usually is when the link between the accident and the injury is medically complex. For non-obvious conditions, an expert opinion tying the event to the harm, stated to a reasonable degree of medical certainty, is generally needed to prove causation.
