Hospital The hospital that published the price, its city and the line exactly as written in its price file.
Cash price The hospital's own price for a patient paying without insurance (“discounted cash” in its price file). Hospitals must publish it under federal law, 45 CFR 180.50. Call to confirm it before booking. More
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
Insurers pay The lowest and highest rates this hospital has agreed with insurance plans for the same item, from its price file. If the cash price is below what your plan pays and you have not met your deductible, paying cash can cost you less. More
Off list How much lower the cash price is than the list price.
No cash discount This line's cash price equals the hospital's full list price. Many hospitals still reduce bills for uninsured patients: ask the billing office for its self-pay discount in writing. More

Inpatient: lowest $12.60, median $78.56, highest $272.00 — a 21.6× difference within the same market.

As an outpatient, the same code is billed by 54 facilities here, median $74.90 — that is the price to compare if you are not being admitted.

Cash or insurance?

At 19 of 22 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 3 it is 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

An electrolyte panel measures sodium, potassium, chloride and bicarbonate (CO2) in one blood sample. It checks fluid and acid balance in people with vomiting, diarrhea, kidney problems or on diuretics.

What the price covers

The price usually covers running the test. The blood draw (36415) is often billed as a separate line.

4 rows held back from this comparison

They are priced below $1 or below a tenth of the national median for code 80051 ($75.14). Such a line is almost always a physician's fee billed separately, an assistant's share or a placeholder — a real charge, but not the price of the procedure itself.
