TMJ Radiographic Images - CDT Code Guide

Diagnostic/Image Capture with Interpretation

Overview

CDT code D0321 refers to the capture of radiographic images of the temporomandibular joint (TMJ), which is crucial for diagnosing TMJ disorders. This procedure involves taking detailed X-ray images that help dental professionals assess the condition of the TMJ, which connects the jawbone to the skull. These images are essential for identifying issues such as arthritis, dislocation, or other abnormalities in the joint. Typically, this code is used when a patient presents with symptoms like jaw pain, clicking, or limited movement, and a thorough examination is required to determine the underlying cause.

When to Use This Code

Evaluation of TMJ function before orthodontic treatment.
Assessment of TMJ condition in patients with a history of trauma to the jaw.
Monitoring changes in TMJ structure in patients with rheumatoid arthritis.
Pre-surgical planning for TMJ-related procedures.

Documentation Requirements

Detailed patient history and symptoms related to TMJ issues.
Clinical notes supporting the necessity of TMJ imaging.
