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 $1,862.25. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.

What it is

Carpal tunnel release cuts the ligament across the palm side of the wrist to take pressure off the median nerve. It is done for numbness, tingling and weakness in the hand that do not improve with splints or injections.

What the price covers

The facility price usually covers the operating or procedure room and recovery. The surgeon and any anesthesia or sedation are billed separately.
