What CMS measured, FY2027

The conditions CMS measured for this hospital in FY2027, with the excess readmission ratio as CMS published it and the median of the hospital’s peer group.
Condition	Eligible discharges	Excess readmission ratio	Peer group median	Counted by CMS
Acute myocardial infarction (AMI)	197	0.9523 at or below 1	1.0042	No
Chronic obstructive pulmonary disease (COPD)	210	1.0539 above 1	1.0028	Yes
Heart failure (HF)	420	1.0376 above 1	1.0143	Yes
Pneumonia (PN)	561	1.0873 above 1	1.0093	Yes
Coronary artery bypass graft surgery (CABG)	24	1.0064 above 1	1.0037	No
Elective total hip or knee arthroplasty (THA/TKA)	25	0.9688 at or below 1	0.9931	No

A ratio above 1 means more readmissions than expected for the hospital’s patients. CMS counts a condition only when it has enough eligible discharges and its ratio is above the median of the hospital’s peer group, so a counted ratio can sit at or below 1. A counted condition adds to the hospital’s reduction, which can round to none.

A cut is a program’s formula at work, not a verdict on a hospital’s care. Nothing on this page ranks hospitals.
