Outpatient: lowest $634.51, median $1,024.00, highest $3,712.15 — a 5.9× difference within the same market.

Both sides : lowest $5,693.27, median $5,693.27, highest $5,693.27.

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 inpatient, the same code is billed by 3 facilities here, median $1,024.00. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.

Cash or insurance?

At 2 of 3 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at none is it 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.
