Costs vary from region to region. That hospital cost seems high by
comparison to a 23 hour hospital stay for a surgical procedure around here,
but the variable may well be in the cost of the lithotripter machine. Many
hospitals don't have them on-site and they are leased on a periodic basis,
which would indeed likely increase the cost to the patient.

Certainly, you should make sure you have an itemized bill and visit the
business office of the hospital in question. You need to make sure that they
didn't make an error, and you would likely be able to negotiate both amount
and payment schedule.

Hospital costs always tend to be shocking compared to professional fees.
