Both sides : lowest $180.72, median $198.81, highest $340.20 — a 1.9× difference within the same market.

Outpatient: lowest $180.72, median $189.77, highest $198.81 — a 1.1× 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 2 facilities here, median $189.77. 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 $198.81. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.
