Inpatient: lowest $21.92, median $26.27, highest $66.04 — a 3.0× difference within the same market.

Cash or insurance?

At 4 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 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

This test looks for the genetic material of Neisseria gonorrhoeae using a nucleic acid amplification test (NAAT). It is run on a urine sample or a swab, often from the same sample as a chlamydia test, and is used for screening and when there are symptoms.

What the price covers

The price usually covers the gonorrhea test only. The visit, the sample collection and a chlamydia test on the same sample (87491) are usually billed separately.

2 rows held back from this comparison

They are priced below $1 or below a tenth of the national median for code 87591 ($105.00). 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.
