Anterior disloc of proximal end of tibia, left knee, subs

This code signifies a left knee injury where the shin bone (tibia) has slipped forward from its normal position relative to the thigh bone (femur). This specific code is used when the patient is receiving follow-up care for this dislocation after the initial treatment.

Apply this code for patients presenting for cast changes, physical therapy, follow-up imaging, or other ongoing management of a previously diagnosed and initially treated anterior dislocation of the proximal tibia in the left knee. It is appropriate for any encounter after the initial treatment phase, but before the condition is fully resolved.

• Ensure documentation clearly specifies "left knee" and "anterior dislocation of proximal tibia."
• Verify the encounter is for subsequent care, not the initial treatment or a sequela.
• Distinguish from other types of knee dislocations (e.g., posterior, medial, lateral) and patellar dislocations.
