Displ seg fx shaft of l tibia, subs for clos fx w routn heal

This code signifies a fracture affecting the shaft of the left tibia, where the bone fragments are no longer in their normal alignment. The fracture is segmental, meaning there are at least two fracture lines isolating a central fragment. This specific code is used when the patient is receiving follow-up care for this injury and the fracture is healing as expected without complications.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed displaced segmental fracture of the left tibial shaft is undergoing routine follow-up. This includes appointments for cast changes, X-ray evaluations confirming expected callus formation, or physical therapy during the normal healing phase of a closed fracture. It should be used when the fracture is progressing well towards union.

• Ensure the documentation specifies "left" tibia and "segmental" fracture of the shaft.
• The "D" seventh character indicates a subsequent encounter for routine healing; do not use for initial treatment or delayed/nonunion.
• Verify the fracture is documented as "closed" to align with this code's specificity.
