We all know the scenario. An injured employee lifts something, twists, or performs a routine movement, and reports a sudden increase in pain. A claim is filed, the process begins, and the clock starts ticking. As the claim file handler, there are statutory timelines that must be met. At the same time, there is pressure from multiple directions. Emergency room records, occupational medicine notes, and the injured employee’s expectations may all point in different directions. This is further complicated by the understandable concern about denying a condition that may be serious or legitimately related to work. We all know that medicine can be complicated, and Worker’s Compensation issues only add an additional layer to that complexity.
Every defensible claim analysis begins with one critical question. What actually happened?
The Importance of the Mechanism of Injury
The objective identification of the mechanism of injury is essential. We need to know what occurred, how it occurred, and whether the forces involved are capable of causing the condition being claimed. The history provided to the ambulance crew, the emergency department triage nurse, and the occupational medicine provider often changes subtly over time. These differences matter.
There is a saying in medicine that common things happen commonly, and rare things happen rarely. A lifting event without a fall or direct trauma generally produces a mild myofascial strain unless there is clear, objective evidence of a more severe injury. This is also where it is critical to distinguish between a sudden traumatic event and gradual onset symptoms, which are far more consistent with degenerative processes rather than an acute work injury. And at this point, frequently review the original reported mechanism of injury, and what is now presented in the clinical records reviewed.
Symptoms Versus Objective Findings
Once the clinical history is obtained, an important truth must be emphasized. Symptoms are not the same as objective findings. Compensability decisions should be grounded in competent, objective, and independently verifiable medical evidence, and not the subjective presentation provided by the injured individual.
It is equally important to remember that workers compensation addresses the compensable injury, not the entire medical situation of the injured individual.
For example, in a 60-year-old individual who is morbidly obese, diabetic, hypertensive and has prior surgical scars; it is clear that not all documented pathology can reasonably be attributed to the specific work event under review.
Understanding the Clinical Examination
When discussing the clinical situation with the injured individual, clarity is essential. Pain, tingling, numbness, weakness, reflex changes, and guarding all have different clinical implications. Each item noted points the evaluator in a different direction.
Injured employees should understand that symptoms can arise from many sources. However, objective findings must reasonably correlate to the reported mechanism of injury for a condition to be considered compensable. The physical examination, as documented by the evaluating clinician, matters.
Imaging Is Not a Diagnosis
Diagnostic imaging studies such as CT or MRI often complicates claims rather than clarifying them. Plain radiographs and MRIs frequently show degenerative changes that represent long standing, preexisting, ordinary disease of life pathology. These findings often existed long before the work event and may never have caused symptoms.
Degenerative changes do not occur suddenly. This is a difficult concept for many injured employees to accept. Just as important, the physical examination findings should guide the interpretation of imaging, not the other way around. All too often we see a normal knee examination followed by an MRI showing a complex tear, and suddenly the next examination documents a positive McMurray’s test.
The Real Question
The key question is not whether pathology exists. The question is whether the documented pathology was caused by the reported mechanism of injury. Claims handlers should expect a clear narrative from medical providers that correlates objective findings, imaging, and mechanism of injury to the work event.
Closing Thoughts
Compensability is not about being unsympathetic. It is about aligning clinical facts with reasonable medical decision-making. Our responsibility is to treat injured employees fairly, provide care that is reasonably required to address the effects of the compensable injury, and make decisions that are medically defensible.
Having a Baseline Clinical Assessment contributes to this decision-making tree. When applied consistently, sound clinical logic protects both the injured worker and the integrity of the claim.
