Lowest and highest amounts each hospital lists for this code as an outpatient, including lines it lists for both settings or without saying which. A doctor’s fee is shown separately when the hospital lists one with the code. “At least” means plans were counted in more than one group and some may be the same plan. This is one line of a bill; most care brings several.
