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

This code describes a complete displacement of the shin bone (tibia) forward from its normal articulation with the thigh bone (femur) at the knee joint. This injury involves the proximal end of the tibia, meaning the part closest to the knee. The "unspecified knee" indicates that the laterality (left or right) is not documented.

Use this code when documentation clearly states an anterior dislocation of the proximal tibia, and the specific knee (left or right) is not identified. This code is appropriate for the initial treatment of such an injury, often following high-energy trauma like motor vehicle accidents or sports injuries.

• Ensure documentation specifies "anterior" dislocation and "proximal end of tibia."
• Only use "unspecified knee" if laterality is truly unstated; otherwise, query for clarification.
• The "A" suffix indicates an initial encounter for active treatment of the dislocation.
