Cash or insurance?
At 8 of 8 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
This test looks for the genetic material of Chlamydia trachomatis using a nucleic acid amplification test (NAAT), the most accurate type of chlamydia test. It is run on a urine sample or a swab and is used for routine screening and when there are symptoms.
What the price covers
The price usually covers the chlamydia test only. The visit, the sample collection and a gonorrhea test on the same sample (87591) are usually billed separately.
1 row held back from this comparison
It is priced below $1 or below a tenth of the national median for code 87491 ($114.40). 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.
