Articular disc disorder of bilateral temporomandibular joint

This code signifies a dysfunction or derangement of the articular disc within both temporomandibular joints (TMJs). This disorder often involves displacement, perforation, or degeneration of the disc, leading to impaired jaw movement and associated symptoms. It is a specific type of internal derangement affecting the cushioning structure between the condyle and the temporal bone.

Apply this code when documentation explicitly states an articular disc disorder affecting both TMJs. This is typically supported by clinical examination findings such as clicking, popping, crepitus, limited jaw opening, or pain localized to both TMJs, often confirmed by imaging studies like MRI.

• Ensure documentation specifies "bilateral" involvement; otherwise, use a code for unilateral involvement.
• Distinguish from other TMJ disorders like osteoarthritis (M26.60-M26.62) or other specified TMJ disorders (M26.69).
• Code any associated pain (e.g., R68.84) or other symptoms separately if documented and clinically significant.
