Number of Medicare patients treated
This shows the number of Medicare patient discharges that a hospital treated for selected conditions, organized by Medicare Severity - Diagnosis Related Groups (MS-DRGs). Patients are assigned to a MS-DRG based on diagnosis, surgical procedures, age, and other information. Providers submit this information on their bills to Medicare, then Medicare uses it to determine how much the provider should be paid. Hospital Compare shows information for each hospital on selected MS-DRGs for the current data collection period. If a MS-DRG has "Complications" or "Comorbidities" in its title, it means that the hospital may have treated some patients that may be considered more complicated.
‘CC’ refers to complications or comorbidities. 'MCC' refers to major complications or comorbidities.
What patients are included
Volume information is for acute care hospitals. Critical access hospitals, VA medical centers, and children’s hospitals are not included because they are paid using another method.
Where the information comes from
CMS calculates the number of patients treated by an individual acute care hospital using data from billing claims submitted to Medicare. Hospitals with zero claims are not included in calculating the U.S. average number of Medicare patients treated per hospital.
