An employee can be injured on the job, and the injury may aggravate a pre-existing physical condition. This is called a combination injury.
The combination of physical problems may make it difficult or impossible for an employee to work. However, even when there may be no question that the new work injury made the old problem worse, the employee can still only receive benefits for the new injury that is directly related to work.
This is mandated by the Workers’ Compensation laws at Mass. G.L. ch 152 section 7 (A). This portion of the law provides that if an injury or disease that is eligible for compensation combines with a non-work-related injury or disease, even if the combination makes the work-related problem worse, the employee may only be compensated to the extent that the new problem is the major cause of the employee’s inability to work.
