Anterior sublux of proximal end of tibia, right knee, subs

This code signifies a partial dislocation of the right tibia forward from its normal position relative to the femur, specifically at the knee joint. This injury indicates that the joint surfaces have lost some alignment but remain in partial contact. The "subsequent encounter" designation means the patient is receiving routine care during the healing or recovery phase of the injury.

This code is used when a patient with a previously diagnosed anterior subluxation of the proximal right tibia is seen for follow-up care, such as cast changes, physical therapy, medication management, or monitoring of healing progress. It applies to encounters after the initial treatment of the acute injury.

• Ensure documentation clearly specifies "anterior subluxation" and not a complete dislocation.
• Verify the laterality is "right knee" and not left or bilateral.
• Confirm the encounter type is for follow-up care, not the initial treatment or sequela.
