This measure estimates a hospital-level, risk-standardized mortality rate (RSMR) for patients 65 years and older discharged from the hospital following a qualifying isolated CABG procedure. Mortality is defined as death from any cause within 90 days of the procedure date of an index CABG admission. The measure was developed using Medicare Fee-for-Service (FFS) patients 65 years and older. An index admission is the hospitalization for a qualifying isolated CABG procedure considered for the mortality outcome. This measure may be used in one or more to be defined 90-day payment models.
The outcome for this measure is 90-day all-cause mortality. Mortality is defined as death for any reason within 90 days of the procedure date from the index admission for patients 65 and older discharged from the hospital after undergoing isolated CABG surgery.

This claims-based measure can be used in the patient cohort aged 65 years or older. The cohort includes admissions for patients who receive a qualifying isolated CABG procedure (see the attached Data Dictionary) and with a complete claims history for the 12 months prior to admission. CMS publicly reports this measure for those patients 65 years or older who are Medicare FFS beneficiaries admitted to non-federal hospitals. If a patient has more than one qualifying isolated CABG admission in the measure period, the first CABG admission is selected for inclusion in the measure and the subsequent CABG admission(s) are excluded from the cohort.
Exclusions
Exclusions
