In the October 1, 2015 Federal Register, the Centers for Medicare and Medicaid Services (CMS) released a Request for Information (RFI) to seek public comment related to new provisions in the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA). This is for the design of the new Medicare physician payment system that will replace the Sustainable Growth Rate (SGR) formula, which includes the merit-based incentive payment system, alternative payment models, and a physician-focused payment model. Originally, comments were due by November 2, 2015; however, an extension of the comment period for an additional 15 days was published in the October 20, 2015 Federal Register, indicating the new due date as Tuesday, November 17, 2015.
