Cash or insurance?
At 7 of 9 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
A transvaginal pregnancy ultrasound uses a small probe placed in the vagina to get close-up pictures. It is most often used early in pregnancy to see the pregnancy and heartbeat, and later to measure the length of the cervix.
What the price covers
The hospital price usually covers the exam. The doctor's reading may be billed separately, and an abdominal pregnancy ultrasound done at the same visit is billed under its own code.
