Cash or insurance?
At the one hospital here that publishes insurer rates for this code, the cash price is not below the highest rate a health plan has negotiated. 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 the level of vitamin B12, which the body needs for red blood cells and nerves. It is ordered to look into anemia, numbness or tingling, memory problems, or conditions and medicines that lower B12 absorption.
What the price covers
