Express Scripts recently released a report which showed that with many workers using medication that is too expensive while on workers' compensation, this is washing approximately $2.1 billion.

The firm's 2011 Workers' Compensation Drug Trend Report showed that $2 billion was wasted on expensive medicines, even though more affordable options are available. Another $107 million was used unnecessarily on billing for third parties and pharmacies that are out of network. There was also $40 million wasted by using more expensive delivery methods to get proper medicine to workers.

"It is critical for employers and payers to get a handle on the costs associated with workers' compensation prescriptions, and we have the solutions to help them to do so, leading to better outcomes for injured workers with minimal disruption," said Tim Pokorney, pharmacist, and clinical director of workers' compensation at Express Scripts.

Consumers who are noticing health insurance rates for their workplace policy are rising, may want to look elsewhere for options. There are many health insurance quotes that may be a better, less expensive option.
