Cash or insurance?

At 10 of 10 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 is the lab (PCR or similar amplification) test for the virus that causes COVID-19. It is more sensitive than a rapid antigen test and is often required before some procedures or travel.

What the price covers

The price usually covers running the test on a swab sample; the collection may be billed separately.
