What it is

An MRI of a lower-limb joint makes detailed pictures of the joint, usually the knee, though the code also covers the hip and ankle. It shows ligaments, cartilage, the meniscus and tendons that do not show on X-rays. No contrast dye is used.

What the price covers

The hospital price usually covers the scan of one joint. The radiologist's reading is often billed separately.
