As an outpatient, the same code is billed by 1 facility here, median $1,042.84 — 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 and below every plan's rate. 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

Radiofrequency ablation uses heat to disable the small nerves that carry pain from lower back facet joints, using imaging to guide the needle.

What the price covers

The price usually covers the injection and imaging guidance. The steroid or other medicine may be billed separately.
