One popular idea for lowering the nation's ballooning health care spending is to change the way insurers pay provider organizations for their care. Instead of paying a fee for each service rendered—a model that can encourage the unscrupulous use of more services even when the benefit is dubious—reformers suggest giving clinical practices a global yearly budget to care for a population of patients. The rationale is that operating with a capped budget would incentivize greater use of preventive care and discourage wasteful services.
