Abdominal ultrasound exams, which include renal ultrasounds, typically cost around $390, as of 2015, according to Cost Helper. The procedure can range from about $200 to about $650, depending on the region of the country and how extensive the ultrasound is.
Patients who have health insurance typically find that a renal ultrasound is covered by insurance, reducing their out-of-pocket costs to a copay of about $10 to $50, as Cost Helper points out. Many clinics and hospitals offer discounts to uninsured patients, and the U.S. Department of Health & Human Services provides a locator to help patients find low-cost clinics. Doctors may order more extensive and expensive tests, such as CT scans or MRIs, depending on the results of the renal ultrasound.
