CMS's description
In October 2012, CMS began reducing Medicare payments for subsection(d) hospitals with excess readmissions under the Hospital Readmissions Reduction Program (HRRP). Excess readmissions are measured by a ratio, calculated by dividing a hospital's predicted rate of readmissions for heart attack (AMI), heart failure (HF), pneumonia, chronic obstructive pulmonary disease (COPD), hip/knee replacement (THA/TKA), and coronary artery bypass graft surgery (CABG) by the expected rate of readmissions, based on an average hospital with similar patients.
