Post disloc of proximal end of tibia, unsp knee, sequela

This code signifies a long-term complication or late effect resulting from a previous posterior dislocation of the upper part of the shin bone in an unspecified knee. It indicates that the initial injury has healed, but the patient continues to experience residual symptoms or conditions directly attributable to that past dislocation.

Apply this code when documenting a patient's current condition that is a direct consequence of a prior posterior proximal tibia dislocation, and the acute phase of the injury has passed. This is appropriate for follow-up encounters addressing chronic pain, instability, limited range of motion, or other persistent issues stemming from the old injury.

• Always use this "S" seventh character for sequela when the acute injury has resolved.
• Do not use this code for the initial or acute treatment of the dislocation; use an acute injury code instead.
• Consider additional codes to specify the nature of the sequela (e.g., chronic pain, osteoarthritis) if applicable.
