Sprain of jaw

This code signifies a ligamentous injury to the temporomandibular joint (TMJ), resulting from overstretching or tearing of the supporting structures. It typically presents with pain, tenderness, and limited jaw movement, often following trauma or excessive mouth opening.

Apply this code when documentation specifies a sprain or strain of the jaw, TMJ, or mandible, without evidence of fracture or dislocation. This is appropriate for injuries like those sustained during a motor vehicle accident, a sports injury, or forceful yawning.

• Differentiate from TMJ disorders (e.g., 524.6x) which involve internal derangement or degenerative changes.
• Ensure documentation clearly states "sprain" or "strain" of the jaw ligaments.
• Do not use if a fracture (e.g., 802.2x) or dislocation (e.g., 830.0x, 830.1x) of the jaw is present; those conditions take precedence.
