I recently had a lumbar spine MRI with and without contrast. My insurance company was charged $4,307 plus an additional $700+ for the radiologist's fee. When I saw the bill, I laughed thinking there must have been a mistake.Nevertheless, the insurance company actually approved $2,500 of the charges.ince receiving the bill, I called some local imaging clinics whose charges range from $500 to $600 for a cash-pay lumbar spine MRI with and without contrast including the films and the radiologist's report.
