Articular disc disorder of left temporomandibular joint

This code signifies a derangement or dysfunction of the articular disc within the left temporomandibular joint (TMJ). This condition often involves displacement, perforation, or degeneration of the disc, leading to symptoms such as pain, clicking, popping, or limited jaw movement.

Apply this code when documentation explicitly states an articular disc disorder affecting the left TMJ. This diagnosis is typically supported by clinical examination findings, patient history of TMJ symptoms, and imaging studies such as MRI that visualize the disc's position and integrity.

• Ensure laterality is clearly documented as "left" to avoid unspecified TMJ codes.
• Distinguish from other TMJ disorders like osteoarthritis or muscle disorders, which have different codes.
• Look for specific terms like "disc displacement with reduction," "disc displacement without reduction," or "perforated disc" to confirm the diagnosis.
