Cash or insurance?

At 10 of 14 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 10 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

This blood test measures 25-hydroxy vitamin D, the form doctors use to judge whether the body has enough vitamin D. It is ordered to check for deficiency, for example with bone loss, certain digestive conditions or while taking supplements.

What the price covers

The price usually covers the vitamin D test only. The blood draw is often billed separately.
