Arthritis of right temporomandibular joint

This code signifies inflammation of the right temporomandibular joint (TMJ), a condition characterized by pain, tenderness, and limited jaw movement. It specifically identifies an arthritic process affecting the articulation between the temporal bone and the mandible on the right side of the face.

Apply this code when documentation clearly indicates a diagnosis of arthritis affecting the right temporomandibular joint. This diagnosis is typically supported by clinical examination findings such as joint tenderness, crepitus, restricted range of motion, and imaging studies confirming arthritic changes.

• Ensure laterality is explicitly documented as "right" to support this specific code.
• Differentiate from other TMJ disorders, such as internal derangement (M26.62-) or other specified disorders (M26.69-).
• Consider sequencing this code with any underlying systemic arthritic conditions, if applicable, following official coding guidelines.
