Workers’ compensation may provide benefits connected to a work-related injury, including medical bills and lost wages. Marker Law evaluates the circumstances of the injury, the available medical documentation, and the effect on your ability to work. The firm also considers whether a third-party claim may apply, because that type of claim can involve additional forms of compensation beyond workers’ compensation benefits.
