Radiology
About 70328: Unilateral jaw joint X-ray, open and closed mouth
Reports plain X-rays of one temporomandibular joint with the mouth open and closed, typically to assess pain, clicking, or restricted jaw movement.
This exam images one temporomandibular joint (TMJ) with the mouth both open and closed. The views show the joint in two positions when a patient has symptoms such as jaw pain, clicking, or limited opening. Images may be acquired in an outpatient imaging department or office, with a radiologist or other qualified clinician interpreting them.
Select 70328 when the ordered and documented plain-film study covers one TMJ in both mouth positions. The report should identify the side examined and describe the open- and closed-mouth views. A study of both joints belongs to 70330 instead. CMS prices 70328 as a diagnostic test with separate professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies image acquisition using equipment and staff, and an unmodified claim represents the complete service. Match the claim to the portion the billing provider furnished.

70328 billing questions
When should 70328 be chosen instead of 70330?
Choose 70328 for open- and closed-mouth radiographs of one TMJ. Use 70330 when the study examines both TMJs.
What documentation supports 70328?
The order and imaging report should establish which joint was examined and that images were obtained with the mouth open and closed.
When is modifier 26 appropriate?
Append modifier 26 when the billing provider supplies only the interpretation of the unilateral TMJ X-rays.
When is modifier TC appropriate?
Append modifier TC when the billing provider supplies the equipment and staff for image acquisition but not the interpretation. Report 70328 without either modifier when that provider furnishes both portions.
Is 70328 the code for a TMJ MRI or contrast arthrogram?
No. 70328 describes plain X-rays taken with the mouth open and closed; TMJ MRI and contrast arthrography have separate codes.
