What the whole procedure costs
The office rate above is what an imaging center, lab or office is paid for the whole test. In a hospital, the facility bills its own fee and the physician bills only the reading. These are 2026 national Medicare amounts.
This is Medicare's separate payment to the facility on top of the physician's fee. For a test like this the physician in a hospital bills only the reading (the professional component); outside a hospital one global fee covers the whole test, shown in the office rate above. Medicare allowed amounts are not what an uninsured patient is charged, and not a quote. Private plans typically allow more.

What these numbers are
Every figure on this page is a 2026 Medicare allowed amount: the physician line comes from the Physician Fee Schedule adjusted by geographic practice-cost indices, and the facility totals come from the CMS hospital outpatient (OPPS) and ambulatory surgery center rates. None of them is a hospital chargemaster price, your insurer's contracted rate, or a quote. Anesthesia, pathology, imaging reads and follow-up care are billed under their own codes when they apply, and an inpatient stay is paid a different way again. In South Dakota the office and hospital physician lines for this CPT differ by $150.97.

Carotid Ultrasound and how South Dakota is priced
All of South Dakota falls under a single payment locality with indices near the bottom of the national scale, cushioned by the work index floor for low-cost states. Sioux Falls and a West River ranch community share one published fee schedule. The state's east-west split, with most people and providers east of the Missouri River, has no counterpart in the pricing structure. That leaves South Dakota with some of the simplest and lowest Medicare pricing in the country.
Sioux Falls has become a genuine regional medical hub, headquarters to large systems whose reach extends across the Dakotas and into neighboring states, while Rapid City anchors care for the West River side and the Black Hills. Vast stretches between them rely on critical access hospitals and tribal facilities, some of the most isolated care settings in America. Referrals to Sioux Falls, Rapid City, or out of state are a routine part of rural care.
This procedure: A bilateral carotid duplex ultrasound examines the arteries on both sides of the neck that supply the brain, measuring plaque buildup and blood flow speed to estimate narrowing. It is ordered after a stroke or mini-stroke, for a bruit heard in the neck, or before certain surgeries. A technologist moves a probe along each side of your neck for 30 to 45 minutes; it is painless, radiation-free, and requires no preparation.
What Is Carotid Ultrasound?
A bilateral carotid duplex ultrasound examines the arteries on both sides of the neck that supply the brain, measuring plaque buildup and blood flow speed to estimate narrowing. It is ordered after a stroke or mini-stroke, for a bruit heard in the neck, or before certain surgeries. A technologist moves a probe along each side of your neck for 30 to 45 minutes; it is painless, radiation-free, and requires no preparation.
What Affects the Cost
- –Hospital vascular labs charge multiples of what office-based or freestanding vascular labs charge for the same bilateral study.
- –Significant narrowing triggers surveillance scans every 6 to 12 months, making the per-scan price a recurring expense for years.
- –Findings can cascade to CT or MR angiography for confirmation, each far more expensive than the ultrasound.
- –The interpreting physician's fee is a separate component at facility-based labs.
- –Screening packages sold directly to consumers by mobile companies price this scan cheaply as cash-pay, but positive findings still funnel into insured follow-up costs.
Questions to Ask Before Booking
- 1.What indication is on my order, and is it one my insurer covers?
- 2.What does this study cost at an office vascular lab versus the hospital?
- 3.If narrowing is found, how often will I need repeat scans and at what cost each?
- 4.Would an abnormal result lead to CT or MR angiography, and what do those cost?
- 5.Is the physician interpretation included in your quoted price?

Carotid Ultrasound in South Dakota: questions
Under 2026 Medicare rates, a carotid ultrasound costs about $281 in total at a hospital outpatient department, counting both the physician and the facility (national rates). Outside a hospital, at an independent imaging center, lab or office, Medicare's full rate in South Dakota averages $187. South Dakota is a single Medicare locality, so the physician rate is the same statewide.
Not on the physician fee schedule. South Dakota uses one locality, so the Medicare physician rate is the same from one end of the state to the other. What still changes is site of service (office vs hospital) and any facility fee the hospital bills on its own claim.
After the Part B deductible, coinsurance is usually 20% of the allowed amount: about $37 for the office physician line or $7 for the hospital physician line in South Dakota. Medigap may cover that 20%. This is not the hospital facility fee.
It depends on where the test is done. At an independent imaging center, lab or office, $186.83 is Medicare's full rate in South Dakota, covering the test and the reading. In a hospital outpatient department the physician is paid only for the reading (about $35.86) and the hospital is paid separately, which brings the national total to about $281. South Dakota ranks #30 of 51 states on the non-hospital rate (within 2% of the national office rate of $189.05).
