Other subluxation of unspecified knee, subsequent encounter

This code signifies a partial dislocation of the knee joint, not otherwise specified, that is being addressed during a follow-up visit. This could involve instability or malalignment of the patella or other knee components without a complete separation of the joint surfaces. The specific anatomical location of the subluxation within the knee is not documented.

Use this code for subsequent encounters where a patient is receiving ongoing care for a previously diagnosed, unspecified knee subluxation. This includes follow-up appointments for physical therapy, medication management, or monitoring of healing after an initial injury or intervention. It is appropriate when the initial treatment has already been rendered and the patient is in the recovery or maintenance phase.

• Ensure documentation clearly indicates this is a subsequent encounter for the subluxation.
• If the specific knee component (e.g., patella, tibia) involved in the subluxation is known, a more specific code should be used.
• Always review the medical record for any additional injuries or complications that may require separate coding.
