As an employer, you know that making sure you provide workers’ compensation benefits for your employees is important and in most circumstances is required by California law. Workers’ compensation provides protection for the employee because it establishes a no-fault system under which an injured worker can receive compensation for his or her work related injuries. It also provides protection for the employers, as this no fault system means that the employer does not have to worry about being sued by their employees for recovery for injuries sustained during the course and scope of employment. Although you certainly understand that workers’ compensation is designed to compensate your injured employee for injuries sustained at your business, it is also important to understand your potential responsibility if the employee had sustained an injury previously at a different business.
Apportionment is designed to allow disability percentages to be assigned to previous injuries to the same body part injured and at issue in the current workers’ compensation case. California Labor Code § 4664(a) states “The employer shall only be liable for the percentage of permanent disability directly caused by the injury arising out of and occurring in the course of employment.” The law goes on to provide that if there is a pervious determination of permanent disability, then it is presumed that the permanent disability still exists at the time the next workers’ compensation claim is made. If the request for apportionment is successful, the amount of workers’ disability benefits received by your employee in the current case will be reduced. To successfully show apportionment, there are specific requirements concerning the doctor’s assessment. First, a doctor must make a specific determination of apportionment. This determination must be done using percentages of what existed at the time of the injury. The doctor must also analyze the permanent disability based on the causation of the disability, not causation of the injury itself. Third, the opinion must be based on facts and not on speculation. Fourth, the opinion must be based on a “reasonable medical probability.” Finally, the doctor must explain how and why he or she reached the particular conclusion. There are other requirements for a successful claim such as showing the employee was actually compensated for the previous injury and the injury continued to be a source of disability after the accident.
