  "description": "The Case Mix Index (CMI) is the average relative DRG weight of a hospital’s inpatient discharges, calculated by summing the Medicare Severity-Diagnosis Related Group (MS-DRG) weight for each discharge and dividing the total by the number of discharges.  The CMI reflects the diversity, clinical complexity, and resource needs of all the patients in the hospital.  A higher CMI indicates a more complex and resource-intensive case load.  Although the MS-DRG weights, provided by the Centers for Medicare & Medicaid Services (CMS), were designed for the Medicare population, they are applied here to all discharges regardless of payer.  Note: It is not meaningful to add the CMI values together.",
