Right. And many insurance companies already reward hospitals and doctors more if the diagnosis methods and treatments were appropriately effective.
For example, if the patient with pneumonia is discharged but re-admitted a week later for recurrence of the pneumonia because they weren't given the appropriate antibiotic, or their bed during hospital stay wasn't at a 30-degree angle, etc...then they get less money from insurance.
Or if a particular emergency department physicians keep ordering unnecessary and expensive diagnostic tests, not only may those tests not be reimbursed, but their "score" for quality of care goes down, and so will their personal reimbursement.
