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

This code signifies a specific type of fracture involving the shaft of the right fibula, characterized by a break in multiple places within the bone segment and displacement of the fractured pieces. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously treated fracture, which has unfortunately healed in an unsatisfactory position (malunion).

Apply this code when documenting ongoing management for a right fibular shaft fracture that has healed improperly, resulting in malunion, and the fracture was initially segmental and displaced. This would be used for patients presenting for evaluation of pain, functional limitations, or planning for corrective surgery related to the malunion.

• Ensure documentation clearly specifies "right" fibula and "segmental" fracture.
• Confirm the encounter is for follow-up care of a closed fracture that has resulted in malunion.
• Differentiate from nonunion (failure to heal) or delayed union (slow healing) as these have different codes.
