U.S. Medicare recipient 30-day readmission rates in 2014, by diagnosis

Diagnoses are grouped using the Clinical Classification Software (CCS). Only CCS with at least 50,000 Medicare index stays, 20,000 Medicaid index stays, 25,000 privately insured index stays, and 5,000 uninsured index stays are shown. “Other” CCS that group a nonspecific set of diagnoses, as well as diagnoses related to cancer and pregnancy, are excluded. Highlighting indicates diagnoses that were not ranked in the top five for either 7-day or 30-day readmissions.
