Outpatient: lowest $4.66, median $24.74, highest $91.50 — a 19.6× difference within the same market.

As an inpatient, the same code is billed by 14 facilities here, median $31.00. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.

3 rows held back from this comparison

They are priced below $1 or below a tenth of the national median for code 85610 ($33.60). 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.
