Question:
Answer:
Assuming documentation indicates bilateral views, you should report a single unit of 70330 (Radiologic examination, temporomandibular joint, open and closed mouth; bilateral). If the imaging was unilateral you would instead report 70328 (... unilateral).As CPT® Assistant (May 2011) explains, "the code descriptor does not specify the number of views." So a single unit of 70330 is sufficient to report bilateral TMJ imaging with the mouth open and closed regardless of the number of views.
Additionally, CMS lists a Medically Unlikely Edit (MUE) of 1 for 70330. That means that if you report more than one unit of 70330 on a claim line, the line will be denied.
