Outpatient: lowest $10.73, median $40.49, highest $252.00 — a 23.5× difference within the same market.
As an inpatient, the same code is billed by 30 facilities here, median $47.50. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.
Cash or insurance?
At 23 of 28 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
A rapid flu test checks a nose or throat swab for influenza within minutes. The code is billed once for each flu type tested, so a test for A and B may be billed twice.
What the price covers
The price usually covers the swab and the test for one flu type; tests for A and B may be billed twice.
