Hospital The hospital that published the price, its city and the line exactly as written in its price file.

List price The hospital's full chargemaster price (“gross charge”) before any discount. Almost nobody pays it; the gap to the cash price shows what the self-pay discount is worth. More

Cash or insurance?

At the one hospital here that publishes insurer rates for this code, the cash price is not 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.

What it is

This lumbar fusion combines an interbody cage placed between two vertebrae with bone graft along the back of the spine, usually with screws and rods. It is the most common single-level lower back fusion, often done at L4-L5 or L5-S1.

What the price covers

The hospital price usually covers the operating room, recovery and supplies. The surgeon and anesthesia usually bill separately, and screws, rods and cages may be billed as implants.
