Outpatient: lowest $2,821.00, median $2,821.00, highest $13,125.00 — a 4.7× difference within the same market.

One side of the body : lowest $38,707.92, median $50,158.09, highest $54,369.60 — a 1.4× 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 3 facilities here, median $3,030.00. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.
