California workers’ compensation law was reformed in 2013, and the reform created various challenges for the parties to a claim. Before January 1, 2013, workers who sustained injuries were entitled to full workers’ compensation benefits regardless of whether the illness or injury they sought compensation for was a “direct injury” or a “compensable consequence” of a direct injury. The reform (Senate Bill 863) added rules that are unique and specific to certain compensable consequence injuries, while workers whose injuries are treated as “direct” remain entitled to all of the same benefits as before. The difficulty of drawing the legal line between a direct injury and a compensable consequence injury is a good illustration of why it helps to consult a California workers’ compensation attorney when facing such a claim. To give clients and readers basic insight into the issue, we have prepared the general explanation below.
What is the distinction between a compensable consequence and a direct injury?
The distinction matters because employees bringing workers’ compensation claims for direct injuries may qualify for higher compensation if it can be shown that they suffered a secondary injury that occurred as a result of the direct injury. In workers’ compensation, a direct injury is one caused by the industrial event itself, while a compensable consequence is a later condition that flows from the original injury or its treatment. For example, you are working in a warehouse and a box full of items falls on you; the injury you sustain is a direct result of that event. In contrast, a compensable consequence injury is a secondary injury which develops as a result of the first, direct injury. Examples include PTSD, sexual dysfunction, a sleep disorder, or an injury to the opposite side of the body that develops from compensating for the first injury. This is a simplified explanation and not a complete list of compensable consequence injuries, and while it may make the issue seem easy to distinguish, in reality this is rarely so.
How is a “compensable consequence” determined?
Compensable consequence is not specifically defined in the Labor Code; the concept comes from case law. The doctrine has been explained in the following terms: “Under this doctrine, where a subsequent injury is the direct and natural consequence of an original industrial injury, the subsequent injury is considered to relate back to the original injury and it generally is not treated as a new and independent injury” (Bates v. Serologicals Corp., 2013 Cal. Wrk. Comp. P.D. LEXIS 194, a WCAB panel decision). That case involved a laboratory technician who suffered an industrial cumulative trauma injury (carpal tunnel) to his right wrist. After returning to work, he had to push a cart of lab equipment, a duty he could perform only with difficulty because of his injured right arm, so he pushed the cart using only his left arm and his hips. One day his left knee gave way and the left side of his lower body was injured. While seemingly unconnected when viewed separately, the injury to the left side of the technician’s body could be seen as a result of his being unable to use both arms while pushing the cart. What the case law points to is that the determining factor is whether the original injury is a contributing cause of the injury in question. That question is reviewed case by case, and the decision rests on the medical evidence.
What are some types of compensable consequence injuries?
The following are examples of situations where the injuries were found to be compensable consequence injuries rather than direct injuries. They help illustrate how the WCAB and the courts approach the question.
Substance addiction
The injured worker sustained a work-related back injury. She subsequently developed an addiction because of her use of pain medication to relieve the back pain caused by the work injury. The court held that treatment had to be provided, because the addiction was caused by the back injury, making it a compensable consequence (Ballard v. Workmen’s Comp. Appeals Bd. (1971) 3 Cal.3d 832, 36 Cal. Comp. Cases 34).
Sexual dysfunction
An industrial back injury is treated with opioid medication, and the medication causes sexual dysfunction. The dysfunction is a consequence of the industrial injury, and Labor Code section 4660.1(c)(1) expressly preserves the worker’s right to medical treatment for sexual dysfunction that is a consequence of an industrial injury, even though it no longer adds to the impairment rating for injuries on or after January 1, 2013.
Sleep disorder
An industrial back injury leaves the worker unable to stay active, the inactivity leads to significant weight gain, and the weight gain leads to sleep apnea. Where the medical evidence ties that chain together, the sleep disorder is a consequence of the industrial injury, and section 4660.1(c)(1) likewise preserves medical treatment for sleep dysfunction that is a consequence of an industrial injury.
This list is not exhaustive; the examples simply demonstrate the logic used in determining compensable consequence injuries. Whether any particular chain of causation is accepted depends on the medical evidence in that case, and WCAB panel decisions such as Bates are persuasive rather than binding authority.
What changes did SB 863 make to compensable consequence injuries in 2013?
Depending on the circumstances, the final permanent disability rating can be increased as a result of a compensable consequence injury. The date of injury matters. For injuries on or after January 1, 2013, the rules for a compensable consequence injury that could increase a worker’s whole person impairment (WPI) changed. Under Labor Code section 4660.1(c)(1), “there shall be no increases in impairment ratings for sleep dysfunction, sexual dysfunction, or psychiatric disorder, or any combination thereof, arising out of a compensable physical injury. Nothing in this section shall limit the ability of an injured employee to obtain treatment for sleep dysfunction, sexual dysfunction, or psychiatric disorder, if any, that are a consequence of an industrial injury.” In other words, these three categories of compensable consequence injury (sleep, sexual, and psychiatric disorders) no longer add to the whole person impairment rating, but the worker remains entitled to medical treatment for them under the workers’ compensation claim. If the worker can show that the disorder is itself a specific industrial injury or an industrial cumulative trauma, rather than a consequence of a physical injury, the WPI increase may still be available. Section 4660.1(c)(2) also preserves an increased rating for a psychiatric injury that results from being a victim of a violent act or from a “catastrophic” industrial injury. When the original injury and its consequences together leave a worker unable to do any substantial work, SSDI benefits may be available on top of workers’ compensation. All of this requires a detailed assessment of your particular facts, which is where a workers’ compensation lawyer comes in.
How important is the medical evidence?
In workers’ compensation claims, medical evidence is always important. Where a compensable consequence is claimed, the medical evidence is the main consideration in deciding the substance of the claim. It is therefore critical that the physician evaluating you understands the concepts and nuances of Labor Code section 4660.1(c) and the workers’ compensation system. The questions that need to be addressed include the following:
- Has the physician correctly explained the mechanism of injury?
- Has the physician identified an injury subsequent to the original industrial injury as a compensable consequence?
- If so, has the medical evaluator provided a thorough analysis and conclusion on the causation of the compensable consequence injury?
- If a WPI increase is requested for the compensable consequence impairment, is the injury subject to the SB 863 limits?
- If the compensable consequence is psychiatric in nature, does it qualify for one of the exceptions to the WPI increase bar under section 4660.1(c)(2)?
- If the argument is that a psychiatric compensable consequence resulted from a “catastrophic” industrial injury under section 4660.1(c)(2)(B), has a physician determined that the underlying physical injury is catastrophic?
- If a WPI increase is appropriate, has the medical evaluator provided a thorough analysis and conclusion on the causation of disability?
