Nondisp seg fx shaft of l tibia, 7thM

This code signifies a non-displaced fracture affecting a segment of the shaft of the left tibia. It specifically indicates that this is a subsequent encounter for a previously diagnosed open fracture, categorized as either Type I or Type II, which has unfortunately failed to heal properly (nonunion).

Utilize this code when documenting follow-up care for a patient with a left tibial shaft fracture that was initially an open fracture (Type I or II) and is now experiencing nonunion. This applies to situations where the fracture fragments are still in their anatomical position without significant displacement.

• Ensure documentation clearly specifies "subsequent encounter" and "nonunion" for an open fracture type I or II.
• Verify the fracture is located in the shaft of the tibia and is non-displaced.
• Confirm the laterality is "left" to avoid coding errors.
