Before you call

The data in this report is from each hospital's publicly filed prices. Here's how to use it.

Confirm the price

Call the hospital's billing department and ask for a price estimate or Good Faith Estimate for Carotid Duplex Scan (CPT 93880). Under federal law, they must provide this. Compare it to the published price in this report.

Ask about cash pay

If you haven't met your deductible, ask for the cash/self-pay rate. At many hospitals, the cash price is lower than the insurance-negotiated rate. You can see this in the insurance table above — some negotiated rates exceed the cash price.

Compare before you schedule

You are not required to use the facility your doctor referred you to. You can request a referral to any in-network facility. The same procedure, same quality — sometimes at a fraction of the price.

Ask about financial help

Most nonprofit hospitals in Virginia offer financial assistance to patients based on household income. This is separate from insurance — even insured patients can qualify. Ask billing for their Financial Assistance Policy.

Financial assistance by facility

Nonprofit hospitals are legally required to have financial assistance programs. Below is what we know about each facility's charitable care.

Facility Status Charity Care Provided How to Apply
Duke University Hospital For-profit — N/A (for-profit)
Duke Regional Hospital Local government — N/A (for-profit)
Unc Hospitals State government — N/A (for-profit)
Duke Health Raleigh Hospital — N/A (for-profit)

What to do next

  1. Identify your top 2-3 facilities based on price, quality rating, and distance. The data in this report shows that lower price does not mean lower quality — check the star ratings.
  2. Call billing before you schedule. Confirm the published price. Ask for a Good Faith Estimate. Ask whether there's a prompt-pay or cash-pay discount beyond the listed rate.
  3. Check your deductible status. If you haven't met your deductible, compare the cash rate to what you'd owe through insurance. In some cases, paying cash is cheaper than using your plan.
  4. Apply for financial assistance if your household income is under $60,000-$125,000 (thresholds vary). Most eligible patients never apply because they don't know the program exists.
  5. Get everything in writing. Before your procedure, get a written price estimate. After, review the bill line by line. Roughly 80% of hospital bills contain errors (Becker's Hospital Review).
