Both sides : lowest $1,426.54, median $3,067.03, highest $4,221.75 — a 3.0× difference within the same market.

Outpatient: lowest $718.25, median $3,903.84, highest $4,147.20 — a 5.8× difference within the same market.

One side of the body : lowest $713.27, median $1,732.90, highest $2,650.70 — a 3.7× difference within the same market.

The two groups are not comparable and are not averaged together: a price for both sides of the body covers twice the work. Merging them is how a single published "median" ends up far above what one side actually costs.

As an inpatient, the same code is billed by 1 facility here, median $1,426.54. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.

What it is

This MRI of a lower-limb joint, often the knee, hip or ankle, is done first without contrast dye and then again after contrast dye is injected into a vein. The extra images can help show infection, tumors or inflammation more clearly.

What the price covers

The hospital price usually covers both sets of images. The radiologist's reading is often billed separately, and the contrast agent may be a separate pharmacy charge.
