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 and 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 carotid ultrasound uses sound waves and Doppler to look at the arteries in the neck that carry blood to the brain. It checks for narrowing or plaque and is ordered after a stroke or mini-stroke, for a bruit heard in the neck, or to follow known artery disease.
What the price covers
The hospital price usually covers the complete study of both sides. The interpretation by a radiologist or vascular specialist is often billed separately.
1 row held back from this comparison
It is priced below $1 or below a tenth of the national median for code 93880 ($811.54). Such a line is almost always a physician's fee billed separately, an assistant's share or a placeholder — a real charge, but not the price of the procedure itself.
