Outpatient: lowest $4.00, median $66.75, highest $123.75 — a 30.9× difference within the same market.

1 row held back from this comparison

It is 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.
