Cash or insurance?
At 6 of 9 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 1 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
The hepatitis B surface antigen test shows whether the hepatitis B virus is present in the blood now. The CDC recommends screening all adults at least once and every pregnant woman in each pregnancy.

1 row held back from this comparison
It is priced below $1 or below a tenth of the national median for code 87340 ($57.00). 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.
