Sprain of jaw, right side, initial encounter

This code signifies a ligamentous injury to the temporomandibular joint (TMJ) on the right side, resulting from overstretching or tearing of the supporting structures. It indicates the initial presentation or active treatment phase of a right-sided jaw sprain.

Apply this code when documentation clearly states a sprain of the right TMJ, often following trauma, excessive yawning, or prolonged mouth opening. Supporting documentation should include a physical exam noting pain, limited range of motion, or tenderness specific to the right jaw, and confirm this is the patient's first encounter for this specific injury.

• Ensure laterality (right side) is explicitly documented; otherwise, an unspecified code may be necessary.
• Verify "initial encounter" status; subsequent care for the same injury requires a different encounter character.
• Distinguish from dislocations (S03.0XXA) or subluxations (S03.42XA) of the jaw, which involve different degrees of joint displacement.
