Other subluxation of left patella, initial encounter

This code signifies a partial dislocation of the left kneecap, specifically when the patella is not fully out of its groove but is abnormally positioned. It covers any subluxation of the left patella that isn't a recurrent or habitual type, and it is used for the initial treatment of this injury.

Apply this code for a patient presenting with a newly diagnosed, non-recurrent subluxation of the left patella. This would include acute injuries where the patella has partially shifted out of alignment for the first time. It is appropriate for the initial evaluation and management of such an event.

• Ensure documentation specifies "left" patella and "subluxation" rather than a full dislocation.
• Confirm this is the patient's first presentation or treatment for this specific subluxation event.
• Do not use for recurrent subluxations; refer to the appropriate "recurrent" codes.
