Medial subluxation of proximal end of tibia, left knee, subs

This code signifies a partial dislocation of the left knee joint where the shin bone (tibia) has shifted inward (medially) relative to the thigh bone (femur). This specific code is used when the patient is receiving follow-up care for this injury, such as cast changes, physical therapy, or monitoring healing.

Apply this code for patients presenting for ongoing treatment of a previously diagnosed medial subluxation of the proximal tibia in the left knee. This includes visits for rehabilitation, wound care related to the injury, or follow-up imaging to assess recovery. Do not use for the initial treatment of the injury.

• Ensure documentation clearly specifies "left knee" and "medial subluxation" of the proximal tibia.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Confirm the subluxation is of the proximal end of the tibia, not other parts of the knee joint.
