Both sides : lowest $834.99, median $834.99, highest $834.99.

Outpatient: lowest $493.63, median $493.63, highest $493.63.

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 1 facility here, median $834.99. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.
