What this number is
The figures on this page are 2026 Medicare physician allowed amounts for a specific CPT code: the professional fee, adjusted by geographic practice-cost indices. They are not a hospital chargemaster price, not your insurer's contracted rate, and not a quote. Hospital facility fees, anesthesia, implants, imaging reads, and pathology are billed separately when they apply.

Carotid Ultrasound and how Missouri is priced
Missouri is a three-locality state: metropolitan St. Louis and metropolitan Kansas City are each priced separately, and everywhere else falls into a rest-of-state locality with lower geographic adjustments. Both metro localities approve higher amounts than outstate Missouri, and the Kansas City locality applies only to the Missouri side of that metro, since the Kansas side prices under Kansas's statewide locality. Springfield, Columbia, and the rural counties all share rest-of-state factors. The metro-versus-outstate gap is the main pricing story here.
St. Louis and Kansas City hold the state's academic medical centers and most of its specialty depth, drawing patients from far beyond Missouri's borders, including southern Illinois and eastern Kansas. Outstate Missouri is served by regional hubs in Springfield, Columbia, and Cape Girardeau, with the Ozarks and Bootheel among the harder places to reach specialty care. Rural hospital viability has been a persistent concern across the state.
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?
