Illinois Medicare physician rate (2026)
-1.2% vs nationalAverage of 4 localities. Office range $177.04–$196.12.
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 Illinois the office and hospital physician lines for this CPT differ by $147.47.

Carotid Ultrasound and how Illinois is priced
Illinois uses one of the more detailed locality maps in the Midwest: Chicago has its own locality, the suburban collar counties are priced separately, the East St. Louis area carries its own locality tied to the St. Louis market, and the rest of the state shares a fourth. Approved amounts step down noticeably from the city and suburbs to downstate, so the same procedure prices differently in Chicago, Naperville, Belleville, and Springfield. This four-way split makes Illinois one of the states where a ZIP-level check genuinely changes the answer. Downstate rates align more closely with neighboring rural states than with Chicagoland.
Chicago is one of the country's great medical hubs, with multiple academic medical centers and deep specialist supply, and its suburbs support large competing systems of their own. Downstate Illinois is a different market: smaller cities like Peoria, Springfield, and Champaign serve wide rural areas, and the Metro East suburbs orient toward St. Louis providers. Where you sit on that map shapes both price and choice.
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?

After the Part B deductible, coinsurance is usually 20% of the allowed amount: about $37 for the office physician line or $8 for the hospital physician line in Illinois. 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, $186.80 is Medicare's full rate in Illinois, covering the test and the reading. In a hospital outpatient department the physician is paid only for the reading (about $39.33) and the hospital is paid separately, which brings the national total to about $281. Illinois ranks #29 of 51 states on the non-hospital rate (within 2% of the national office rate of $189.05).
