Cash or insurance?
At 7 of 10 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
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
The price usually covers the B12 test only. The blood draw is often billed separately, and folate (82746) or follow-up tests are separate codes.
1 row held back from this comparison
It is priced below $1 or below a tenth of the national median for code 82607 ($79.28). 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.
