Cash or insurance?

At 3 of 3 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 2 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

NIPT analyzes fragments of fetal DNA that circulate in the mother's blood to screen for Down syndrome (trisomy 21) and trisomies 18 and 13. It can be done from about 10 weeks of pregnancy. It is a screening test, so a positive result needs a diagnostic test to confirm.

What the price covers

The price usually covers the DNA analysis of one blood sample. The blood draw, genetic counseling and any added screens, such as sex chromosomes or microdeletions, may be billed separately.
