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

This code describes a forward displacement of the shin bone from its normal articulation with the thigh bone, affecting an unspecified knee joint. This specific code is used when the patient is receiving follow-up care for a previously diagnosed anterior tibial dislocation.

Apply this code for encounters where a patient is being treated for the ongoing management, healing, or complications of an anterior dislocation of the proximal tibia. This includes visits for cast changes, physical therapy, or follow-up imaging after the initial injury and treatment.

• Ensure documentation clearly indicates "subsequent encounter" for the dislocation.
• Verify the dislocation is specifically "anterior" and of the "proximal end of tibia."
• Do not use this code for initial treatment of the injury; refer to the appropriate initial encounter code.
