Inpatient: lowest $15.39, median $55.80, highest $162.60 — a 10.6× difference within the same market.

Cash or insurance?

At 10 of 12 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 3 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

Rheumatoid factor is an antibody found in many people with rheumatoid arthritis. The test is part of the workup for joint pain and swelling.

What the price covers

The price usually covers running the test. The blood draw (36415) is often billed as a separate line.
