On October 1, 2015, CMS published a request for information (RFI) regarding implementation of Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) provisions that mandate significant reforms of the Medicare physician payment system. As previously reported, MACRA repealed the sustainable growth rate methodology (SGR) for updating the Medicare physician fee schedule, and after a period of stable updates, it establishes a new Merit-based Incentive Payment System (MIPS). MACRA also consolidates current Medicare quality programs, and promotes the development of Alternative Payment Models (APMs) and physician-focused payment models (PFPMs). The RFI invites public input on numerous detailed questions regarding the new payment framework; CMS will consider this feedback as it develops its proposed policy for the MIPS. Comments will be accepted until November 2, 2015. CMS also is hosting webinars on October 8 and October 15, 2015 to discuss the RFI; registration is required. *Note that CMS subsequently extended this comment period until November 17, 2015.
