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.

Medicare (traditional) reference

Only for people on original Medicare. These are CMS’s 2026 amounts. They aren’t what private insurance or cash patients pay.
