    CPT 70328: TMJ Radiographic Imaging, Open and Closed Mouth

    Medicare pays $24 on average nationally for this procedure.

    CPT code 70328 describes radiographic imaging of one temporomandibular joint (TMJ) performed with the mouth both open and closed to evaluate TMJ arthralgia or abnormal clicking that may indicate an articular disc disorder; the service is diagnostic radiography and is typically performed in an outpatient imaging center or office-based radiology setting using intraoral/extraoral X‑ray techniques to capture comparative views of the joint in different jaw positions.

    For related coverage guidance, see recent payer policy updates: Lumbar Microdiscectomy, Artificial Cervical Intervertebral Disc, Lumbar Decompression.

    Clinical & Coding Specifications

    Clinical Context

    A 35-year-old female presents to an outpatient oral and maxillofacial radiology suite with a 6-month history of jaw pain and intermittent clicking on the right side when opening and closing her mouth. History and physical exam suggest temporomandibular joint (TMJ) arthralgia with possible articular disc displacement. The provider orders TMJ radiographs with closed- and open-mouth views to evaluate joint space, condylar position, and dynamic relationship of the articular surfaces. The radiology technologist obtains bilateral or unilateral oblique transcranial radiographs per the provider request. Images are processed and archived to the PACS; the interpreting dentist/oral and maxillofacial radiologist documents findings and delivers a diagnostic report. Billing uses 70328 for open and closed views from one side of the TMJ; modifier use follows payer and clinical circumstances (e.g., laterality or professional component billing). Typical site of service is an outpatient radiology department, dental clinic, oral and maxillofacial surgery clinic, or ambulatory imaging center. The patient may be referred by a general dentist, primary care clinician, or an oral and maxillofacial surgeon for evaluation of TMJ pain, clicking, or suspected internal derangement.
