In order to receive performance-based payments, the practices must demonstrate a lowered spending per treatment episode when compared to benchmark standards.[1] The benchmark is determined through the use of a risk-adjustment of expenditures compared to "a historical baseline period trended forward to the current performance period."[2]:115 The program requires that practices report the outcome of their treatments and compares that to quality metrics to determine the level of reimbursement to the practice. A number of healthcare provider groups have announced that they have developed systems of reporting specifically designed for oncology to meet the demands of OCM and its EHR requirements.
