Medial disloc of proximal end of tibia, right knee, init

This diagnosis describes a specific injury where the upper portion of the right shin bone (tibia) has shifted inward from its normal position relative to the thigh bone (femur) within the knee joint. This indicates a complete separation of the joint surfaces on the medial side.

This code is appropriate for the initial encounter of a patient presenting with a documented medial dislocation of the proximal tibia in the right knee. This typically occurs due to significant trauma, such as a motor vehicle accident or a fall from a height, resulting in acute knee instability and pain.

• Ensure documentation specifies "medial" dislocation and "proximal end of tibia" for accurate code assignment.
• Confirm the laterality is "right knee" and the encounter is the "initial" treatment for the injury.
• Do not use this code for subluxations or dislocations of other knee components; specific codes exist for those conditions.
