Outpatient: lowest $9.54, median $65.25, highest $83.85 — a 8.8× difference within the same market.

As an inpatient, the same code is billed by 11 facilities here, median $66.39. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.

8 rows held back from this comparison

They are priced below $1 or below a tenth of the national median for code 85730 ($50.00). Such a line is almost always a physician's fee billed separately, an assistant's share or a placeholder — a real charge, but not the price of the procedure itself.
