How to Use the Cost Sharing Tool

The Centers for Medicare & Medicaid Services (CMS) provides issuers and states with a number of review tools to check QHP Application data for errors that would result in corrections following submission. The Cost Sharing Tool runs four different reviews to help ensure that health plans satisfy the cost sharing standards for QHP certification. These four reviews include the Maximum Out of Pocket Review, the Cost Sharing Reduction Plan Variation Review, the Catastrophic Plan Review, and the Expanded Bronze Plan Review. This video discusses the purpose of the tool, provides an overview of the tool’s layout, and walks viewers through running the tool using test data from the QHP Application templates.
