TMJ Arthrogram - CDT Code Guide

Diagnostic/Image Capture with Interpretation

Overview

CDT Code D0320 refers to the temporomandibular joint (TMJ) arthrogram, a diagnostic imaging procedure that includes the injection of contrast material into the TMJ. This procedure is typically used to evaluate the joint's structure and function, providing detailed images that help in diagnosing conditions such as TMJ disorders, arthritis, or joint injuries. During the procedure, a contrast dye is injected into the joint space, and X-rays or other imaging techniques are used to capture detailed images of the joint. This helps in identifying abnormalities in the joint's anatomy or function, which can aid in planning further treatment or surgical interventions.

When to Use This Code

  • Suspected TMJ disorder with unclear diagnosis
  • Pre-surgical evaluation of TMJ
  • Assessment of TMJ arthritis
  • Investigation of TMJ pain with no clear cause
  • Evaluation of joint function after trauma

Documentation Requirements

  • Detailed patient history and symptoms
  • Clinical indications for the procedure
  • Consent form signed by the patient
  • Description of the procedure performed

Billing Considerations

When billing for D0320, ensure that the procedure is justified by clinical necessity. Check with the patient's insurance for coverage specifics, as some plans may require prior authorization. Be aware of any frequency limitations on diagnostic imaging for TMJ conditions. Common modifiers that may apply include those indicating bilateral procedures or reduced services.
