Workers' compensation insurance provides cash benefits and health care for workers who are injured on the job. This DataWatch considers the costs and benefits of combining the health insurance component of workers' compensation with universal health insurance, creating a twenty- four-hour coverage plan. The paper documents a large potential savings from twenty-four-hour coverage: Workers' compensation medical charges are about twice as high as those for comparable off-work injuries. This disparity seems to result from price discrimination and lack of cost controls in workers' compensation. Twenty-four-hour coverage, however, may be difficult to implement.
