On November 19, 2013, CMS published a notice seeking comments on its proposed Quality Rating System (QRS) framework for rating Qualified Health Plans (QHPs) offered through an ACA Affordable Insurance Exchange. Specifically, CMS lists proposed QRS quality measures that QHP issuers would be required to collect and report, and describes the hierarchical structure of the measure sets and elements of the QRS rating methodology. In addition, the notice solicits comments on how to ensure the integrity of QRS ratings, along with priority areas for future QRS measure enhancement and development. CMS will accept comments on the QRS framework until January 21, 2014.
