2025 CPT code 70332

Temporomandibular joint arthrography with radiological supervision and interpretation.

Follow all applicable CPT coding guidelines. Proper documentation is essential for accurate coding and reimbursement.Ensure that both the supervision and interpretation components are properly documented and supported by the clinical encounter.

Modifiers such as -50 (bilateral procedure), -26 (professional component only), and -TC (technical component only) may be applicable depending on the specific circumstances of the procedure and who performed what components.

Medical necessity for TMJ arthrography is established when other less invasive imaging modalities (e.g., plain radiography, MRI) are insufficient to provide a definitive diagnosis of TMJ pathology. The arthrography should be ordered for suspected internal derangements, inflammatory arthritis, or trauma, where visualization of the internal structures of the TMJ is critical for proper management.

The radiologist is responsible for injecting the contrast material (if performed by the radiologist), performing the imaging study, and interpreting the images to provide a diagnostic report.

IMPORTANT This code should not be reported with 77002.Codes 70328 and 70330 describe plain film radiography of the TMJ (without contrast).Code 70336 describes MRI of the TMJ.

In simple words: This medical code covers a special X-ray of your jaw joint (TMJ). A doctor injects a special dye into the joint, then takes X-rays to examine it closely. Another doctor supervises this procedure and interprets the X-ray results to help diagnose problems with the jaw joint.

This CPT code encompasses the radiological supervision and interpretation of a temporomandibular joint (TMJ) arthrography.The procedure involves injecting a contrast medium into the TMJ to visualize the joint structures and assess for abnormalities. The radiologist provides personal supervision during the procedure and interprets the resulting images.This code does not include the injection procedure itself, which should be billed separately using CPT code 21116 if performed by the same provider.If the arthrography is performed bilaterally, the code should be reported twice.

Example 1: A patient presents with jaw pain and limited range of motion.The radiologist performs a bilateral TMJ arthrography under personal supervision to assess for internal derangements such as a meniscus tear or displacement., A patient with a history of trauma to the face requires a TMJ arthrography to evaluate for ligamentous injuries or fractures that are not clearly visible on standard X-rays., A patient with suspected inflammatory arthritis affecting the TMJ undergoes a TMJ arthrography to assess for joint erosion, synovitis, or other features of the disease.
