This is what a hospital system in Pennsylvania is trying out:
The group, Geisinger Health System, has overhauled its approach to surgery. And taking a cue from the makers of TVs, washing machines and other products, Geisinger essentially guarantees its workmanship, charging a flat fee that includes 90 days of follow-up treatment.
Even if a patient suffers complications or has to come back to the hospital, Geisinger promises not to send the insurer another bill.
