Other subluxation of right knee, initial encounter

This code signifies a partial dislocation of the right knee joint, where the bones are still in contact but are improperly aligned. This injury is less severe than a full dislocation and can involve various structures within the knee, such as the patella or tibiofemoral joint.

Apply this code for initial encounters with patients presenting with a subluxation of the right knee that is not specifically identified as a patellar subluxation. This includes cases where the physician documents "other subluxation of right knee" without further specification of the involved bone.

• Ensure documentation specifies "right knee" and "subluxation" rather than a full dislocation.
• Confirm this is the patient's initial encounter for this specific injury.
• If the subluxation is specifically of the patella, a more specific code (e.g., S83.311A) should be used.
