Both sides : lowest $284.07, median $352.00, highest $440.00 — a 1.5× difference within the same market.

Outpatient: lowest $216.50, median $288.92, highest $701.28 — a 3.2× difference within the same market.

The two groups are not comparable and are not averaged together: a price for both sides of the body covers twice the work. Merging them is how a single published "median" ends up far above what one side actually costs.

As an inpatient, the same code is billed by 10 facilities here, median $352.00. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.

As an inpatient, the same code is billed by 4 facilities here, median $701.28. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.
