Cash or insurance?
At 2 of 2 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
A complete blood count (CBC) with differential measures red blood cells, white blood cells, hemoglobin, hematocrit and platelets, and breaks the white cells down into their types. It is used to check for anemia, infection, inflammation and many other conditions.
What the price covers
The price usually covers the automated CBC and differential. The blood draw is often billed separately, and a manual smear review, if needed, can be an extra code.
