The 2016 Workers' Compensation Large Deductible Study provides regulators, workers' compensation insurers and employers with valuable information about the appropriate use of large deductibles. It is intended to serve as a resource to insurers, third party administrators, professional employer organizations, guaranty associations and regulators showing how large deductible policies work and special issues that can arise with their use. The paper revisits and reconsiders issues raised in a similar 2006 Workers' Compensation Large Deductible Study.
