    Clinical & Coding Specifications

    Clinical Context

    A 34-year-old patient presents to an oral and maxillofacial clinic with several months of right-sided preauricular pain, intermittent locking, and audible clicking when opening and closing the jaw. The pain is worse with chewing and jaw function and partially relieved by soft diet and NSAIDs. The dentist refers the patient for imaging to evaluate the temporomandibular joint (TMJ) for suspected articular disc displacement or degenerative joint disease.

    The provider schedules bilateral TMJ radiographic imaging performed with the mouth closed and mouth open to assess joint alignment, condylar translation, and presence of disc displacement or degenerative changes. The procedure is typically performed in an outpatient radiology suite, dental office with radiography capabilities, or oral/maxillofacial clinic. The technologist obtains standardized bilateral TMJ views (open and closed), the images are reviewed by the interpreting physician (oral and maxillofacial radiologist or dentist with imaging privileges), and findings are documented in the radiology report to guide management such as conservative therapy, referral to oral surgery, or further advanced imaging (MRI) if soft-tissue assessment is required.
