Displ seg fx shaft of r fibula, subs for clos fx w nonunion

This code describes a situation where a patient has a fracture in the shaft of their right fibula that is broken into multiple pieces (segmental) and the bone fragments are not properly aligned (displaced). Crucially, this code is used when the fracture has failed to heal after a previous treatment attempt (nonunion) and the skin over the fracture site remains intact (closed).

Use this code for follow-up encounters where a patient is being treated for a right fibula shaft fracture that has not healed and is still displaced and segmental. This applies to situations such as ongoing management of the nonunion, evaluation for further surgical intervention, or monitoring of conservative treatment for the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right fibula shaft.
• Verify the fracture is explicitly described as "segmental" and "displaced."
• Confirm this is a subsequent encounter for a closed fracture; do not use for open fractures or initial encounters.
