Cash or insurance?

At 20 of 21 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 9 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

A magnesium test measures the level of magnesium in the blood. Doctors order it for muscle cramps or weakness, an irregular heartbeat, low potassium or calcium that does not correct, and for people on diuretics, long-term acid-reducing drugs or with kidney disease.

What the price covers

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