Recurrent dislocation, left shoulder

This code signifies an instability of the left shoulder joint where the humerus repeatedly displaces from the glenoid cavity. It indicates a chronic condition of shoulder dislocation that has occurred multiple times, rather than an initial or acute event.

Apply this code when documentation clearly states "recurrent dislocation" or "chronic instability" of the left shoulder. Supporting documentation should include a history of previous dislocations and the current episode. This code is appropriate for both traumatic and atraumatic recurrent dislocations.

• Always specify laterality (left, right, bilateral) for shoulder conditions.
• Distinguish carefully between initial dislocation (S43.0-) and recurrent dislocation (M24.4-).
• Do not use this code for subluxation; a full dislocation must be documented.
