Cash or insurance?
At 2 of 11 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at none is it below every plan's rate. If you have insurance but have not met your deductible, you usually pay your plan's negotiated rate, which falls somewhere in the "Insurers pay" column. Paying cash can cost less, but a cash payment usually does not count toward your deductible. Ask the hospital for both numbers before you book.
What it is
An MRI of the thoracic spine makes detailed pictures of the middle section of the spine, between the neck and the lower back, including discs, vertebrae and the spinal cord. It is ordered for mid-back pain, suspected fractures or nerve symptoms. No contrast dye is used.
What the price covers
The hospital price usually covers the scan of the mid-back section only. The radiologist's reading is often billed separately.
