Commission on Cancer (CoC) centers with the highest case mix index
Case Mix Index (CMI) reflects the complexity of a hospital’s patient population and the associated resources for their care.
The Centers for Medicare and Medicaid Services (CMS) uses CMI to determine reimbursement for Medicare and Medicaid beneficiaries. CMS evaluates the resources required to treat patients where higher CMI can result in higher reimbursement rates.
What is a Commission on Cancer (CoC) Center?
Commission on Cancer (CoC) Centers are nationally recognized for data-driven performance measures that improve care quality for patients undergoing cancer treatment.
The American College of Surgeons (ACS) runs this consortium of organizations to provide educational/training opportunities and development resources, reporting tools via participation in the National Cancer Database, as well as advocacy.
