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

This diagnosis code signifies a complete displacement of the upper portion of the shin bone (tibia) backward from its normal articulation with the thigh bone (femur) in the right knee joint. This injury typically results from significant trauma, often involving a direct blow to the front of the knee or hyperextension.

Use this code for the initial encounter of a patient presenting with a newly diagnosed posterior dislocation of the proximal right tibia. This code is appropriate for documenting the acute injury and the initial treatment provided, such as reduction or stabilization.

• Ensure documentation specifies "posterior" dislocation and "proximal end of tibia" to differentiate from other knee dislocations.
• Verify the laterality is "right knee" as specified by the code.
• Confirm this is the "initial encounter" for treatment of this specific injury; subsequent care will require a different seventh character.
