In simple words: An MRI scan of a joint in your lower leg (like your hip, knee, or ankle) is taken using a special dye to help see the joint better. The scan uses a powerful magnet and radio waves to create detailed pictures, which a doctor then reviews.

This procedure involves magnetic resonance imaging (MRI) using contrast material to visualize any joint in the lower extremity. It includes the technical and professional components of the service. The patient is positioned within the MRI scanner, and images are acquired. The radiologist interprets the images and prepares a report.

Example 1: A patient presents with chronic knee pain and suspected meniscus tear. An MRI of the knee with contrast is ordered to evaluate the joint and surrounding tissues., A patient has ankle instability following a sports injury. An MRI of the ankle with contrast is performed to assess ligament damage and bone abnormalities., A patient experiences persistent hip pain and limited range of motion. An MRI of the hip with contrast is requested to investigate possible labral tears or other joint pathology.

Documentation should include the patient's medical history, physical exam findings, the reason for the MRI, the specific joint imaged, the type of contrast used, and the radiologist's interpretation report.

** For MRI without contrast, use 73721. For MRI without contrast, followed by with contrast and further sequences, use 73723. For only the professional component use modifier 26. For only the technical component, use modifier TC (if applicable by payer). Modifier 50 (Bilateral Procedure) is typically not used for bilateral radiology procedures. Instead, consider using LT, RT, 59 modifiers, or billing the code twice (depending on payer preferences.)
