Cash or insurance?
At 1 of 2 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 1 it is below every plan's rate.

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.
What it is
Shock-wave lithotripsy breaks kidney or ureter stones into small pieces with sound waves aimed from outside the body, so the pieces can pass in the urine. No cut is made, and it is usually done under sedation or anesthesia.
What the price covers
The listed price usually covers the lithotripsy treatment in the facility. The urologist, anesthesia, X-rays and any stent placement are often billed separately; some hospitals rent the machine from an outside company, which can change how the charge is listed.
