How To Use CPT Code 70332

CPT 70332 describes the radiographic contrast joint study known as arthrography of the temporomandibular joint (TMJ). This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 70332?

CPT 70332 is used to describe a radiographic contrast joint study called arthrography of the temporomandibular joint (TMJ). This procedure involves injecting a radiopaque substance into the TMJ to visualize the structure and position of the joints. The physician supervises the entire radiological procedure and interprets the findings.

2. Official Description

The official description of CPT code 70332 is: ‘Temporomandibular joint arthrography, radiological supervision and interpretation.’

3. Procedure

1. During the arthrography of the TMJ, the physician injects a radiopaque substance into the temporomandibular joint.
2. X-rays are taken in multiple projections to visualize the joint and its structures.
3. The contrast material allows the radiologist to see more details than a conventional X-ray.
4. The physician supervises the entire procedure and interprets the findings.

4. Qualifying circumstances

CPT 70332 is used for patients who require a radiographic contrast joint study of the TMJ. This procedure is performed for diagnostic purposes to assess the structure and position of the joints. The physician must provide radiological supervision and interpretation throughout the procedure.

5. When to use CPT code 70332

CPT code 70332 should be used when performing arthrography of the TMJ, which involves injecting a contrast material into the joint and taking X-rays in multiple projections. This code is used for diagnostic purposes to evaluate the TMJ and its structures. It should not be reported in conjunction with code 77002.

6. Documentation requirements

To support a claim for CPT 70332, the following documentation is required:

• Indication for the arthrography of the TMJ
• Details of the radiographic procedure performed
• Date and time of the procedure
• Supervision and interpretation by the physician

7. Billing guidelines

When billing for CPT 70332, ensure that the physician provides radiological supervision and interpretation throughout the procedure. This code should not be reported with code 77002. If the procedure is performed on both the right and left sides, CPT 70332 and code 21116 should be reported twice.

8. Historical information

CPT 70332 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates to the code since its addition.

9. Examples

1. A patient undergoes arthrography of the TMJ to assess the position and structure of the joints.
2. The physician performs radiographic contrast joint study of the TMJ to evaluate a patient’s jaw pain.
3. Arthrography of the TMJ is performed to visualize the joint and its structures in a patient with suspected TMJ disorder.
4. A radiologist injects contrast material into the TMJ and takes X-rays in multiple projections to assess a patient’s TMJ condition.
5. The physician supervises the arthrography of the TMJ and interprets the findings to aid in diagnosis.
6. A patient undergoes arthrography of the TMJ to assess the effectiveness of previous TMJ treatment.
7. The radiologist performs a radiographic contrast joint study of the TMJ to evaluate a patient’s jaw mobility.
8. Arthrography of the TMJ is performed to assess the position and structure of the joints in a patient with TMJ dysfunction.
9. A physician injects contrast material into the TMJ and takes X-rays in multiple projections to aid in the diagnosis of a patient’s TMJ disorder.
10. The physician supervises the arthrography of the TMJ and interprets the findings to guide further treatment.
