Temporomandibular joint arthrography, as denoted by CPT® Code 70332, is a specialized diagnostic imaging procedure focused on the temporomandibular joint (TMJ). This technique involves the injection of a contrast agent, typically radioactive iodine, directly into the joint space. The primary purpose of this procedure is to visualize the intricate contours of the soft tissues within the TMJ, which is essential for diagnosing various conditions associated with temporomandibular joint disease. The arthrography process is performed using a single 27-gauge needle, which is utilized to inject the contrast material into both the upper and lower compartments of the joint. The resulting images, which may be captured through methods such as videofluoroscopy, display the contrast agent in a greyish or whitish hue, allowing for detailed assessment of the joint's internal structures. This imaging technique is particularly valuable for identifying issues such as displacement or abnormal morphology of the meniscus, perforations in the disk or meniscal attachments, adhesions within the joint capsule, and any abnormalities in the shape or function of the disk itself. By providing a clear view of these internal components, TMJ arthrography plays a crucial role in the accurate diagnosis and management of TMJ disorders.

The indications for performing temporomandibular joint arthrography (CPT® Code 70332) include the following conditions and symptoms:
The procedure for temporomandibular joint arthrography involves several key steps to ensure accurate imaging and diagnosis:
After the completion of temporomandibular joint arthrography, patients may be advised to rest and avoid strenuous activities for a short period. It is important to monitor for any signs of complications, such as increased pain, swelling, or signs of infection at the injection site. Patients may also be instructed to follow up with their healthcare provider to discuss the results of the imaging and any further management or treatment options based on the findings. Recovery is typically swift, and most patients can resume normal activities shortly after the procedure, barring any specific instructions from their physician.

| 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) |
