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

A CRP test measures C-reactive protein, which the liver makes when there is inflammation in the body. It is used to look for infection or inflammatory conditions and to follow how they respond to treatment.

What the price covers

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