Articular disc disorder of right temporomandibular joint

This code identifies a specific internal derangement of the right temporomandibular joint (TMJ) involving the articular disc. This condition typically manifests as pain, clicking, popping, or limited jaw movement due to displacement or degeneration of the disc that cushions the joint.

Apply this code when documentation clearly indicates a diagnosis of an articular disc disorder affecting the patient's right TMJ. Supporting clinical notes should detail findings such as disc displacement with or without reduction, degenerative changes of the disc, or perforation, specifically localized to the right side.

• Ensure laterality is explicitly documented as "right" to support this specific code.
• Distinguish from other TMJ disorders, such as osteoarthritis (M19.2xx) or other specified derangements (M26.69x).
• Look for diagnostic confirmation via imaging (e.g., MRI) or clinical examination findings consistent with disc pathology.
