Recurrent dislocation, left knee

This code signifies an unstable left knee joint where the patella or other joint components repeatedly displace from their normal anatomical position. It indicates a chronic issue of recurrent subluxation or dislocation, rather than an acute, isolated event. This condition often leads to pain, instability, and functional impairment of the knee.

Apply this code when documentation clearly indicates a history of multiple dislocations of the left knee, not just a single occurrence. This is appropriate for patients presenting with ongoing symptoms related to the knee's instability due to these recurrent events. Supporting documentation should include a history of previous dislocations and current symptoms consistent with chronic instability.

• Ensure the documentation specifies "recurrent" or "chronic" dislocation, not just a single, acute dislocation.
• Verify laterality; this code is specific to the left knee.
• Do not confuse with M24.362 (Pathological dislocation, left knee) which implies an underlying disease causing the dislocation, rather than mechanical instability.
