Outpatient: lowest $264.96, median $397.80, highest $443.52 — a 1.7× difference within the same market.

One side of the body : lowest $246.89, median $260.00, highest $303.55 — a 1.2× 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 4 facilities here, median $397.80. 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 1 facility here, median $246.89. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.
