“…25 Among the options identified by Rand, adoption of a bundled payment method, in which insurers would be encouraged "to provide a single payment for all services related to a treatment or condition" and thereby provide "a financial incentive to reduce the volume or intensity of services" was assessed as the most promising, with an estimated potential cost savings of up to 5.9% of projected total medical expenditure from 2010 to 2020. 25 A special Massachusetts commission tasked with addressing the state's cost overrun problem reached a similar conclusion, finding that paying providers on a fee-for-service basis "is a primary contributor to the problem of escalating costs and pervasive problems of uneven quality." 29 The commission recommended replacing fee-for-service reimbursement with a "global payment system" that would go beyond bundled payment methods that are episode-or setting-based, such as diagnosis-related groups (DRGs), and "prospectively compensate providers for all or most of the care that their patients may require over a contract period, such as a month or year."…”
