Inpatient: lowest $292.50, median $331.45, highest $370.40 — a 1.3× difference within the same market.

Both sides : lowest $438.75, median $438.75, highest $438.75.

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 outpatient, the same code is billed by 2 facilities here, median $331.45 — that is the price to compare if you are not being admitted.

Cash or insurance?

At the one hospital here that publishes insurer rates for this code, the cash price is below the highest rate a health plan has negotiated. If you have insurance but have not met your deductible, you usually pay your plan's negotiated rate, which falls somewhere in the "Insurers pay" column. Paying cash can cost less, but a cash payment usually does not count toward your deductible. Ask the hospital for both numbers before you book.
