Cash or insurance?

At the one hospital here that publishes insurer rates for this code, the cash price is 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

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.
