Outpatient: lowest $4.35, median $64.26, highest $532.00 — a 122.3× difference within the same market.
As an inpatient, the same code is billed by 20 facilities here, median $63.00. 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 17 of 30 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
A BUN test measures urea nitrogen, a waste product removed by the kidneys. It is used with creatinine to check kidney function and hydration.
What the price covers
The price usually covers running the test. The blood draw (36415) is often billed as a separate line.
