The current fee-for-service health-care payment system encourages doctors to perform more tasks rather than overseeing a patient’s overall care from beginning to end. That has led to expensive, disjointed, and often mediocre service, as well as wide price variation to treat similar conditions. Bundling payments, by grouping a set of services over a given period into one payment, gives providers an incentive for efficiency and coordination that is absent in today’s fee-for-service model.
