On April 16, 2015, the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) was signed into law. Among other functions,1 MACRA further delayed the implementation of the much-anticipated provisions of the 2014 Inpatient Prospective Payment System Final Rule affecting reviews of inpatient admissions, including new guidelines for inpatient admissions known as the “two-midnight” rule, until October 1, 2015.
