The U.S. Departments of the Treasury, Labor, and Health and Human Services (the “Departments”) recently issued proposed rules requiring fully-insured and self-funded employer-sponsored group health plans and health insurance issuers to provide participants with an Internet-based tool that shows estimated cost-sharing information for specific covered services and providers (based on network rates and allowable amounts for out-of-network providers) prior to receiving services, similar to the information currently provided to participants via an Explanation of Benefits (or EOB) after services are rendered. The participant would also be able to request a hard copy of this information. In addition, the proposed rules would require the group health plan to publish its network negotiated rates and historical allowed amounts for out-of-network providers. Grandfathered plans and excepted benefits would not be subject to the proposed rules. The proposed rules have a 60-day comment period, and the Departments have proposed that the rules would be effective for plan years beginning on or after one year following the date that the rules are finalized. The proposed rules are available here.
