Disp fx of lateral malleolus of unsp fibula, 7thQ

This code describes a previously treated, open fracture (Gustilo type I or II) of the lateral malleolus of an unspecified fibula that has healed in an unsatisfactory position, resulting in malunion. The fracture was initially displaced, and this code is used for follow-up care related to the malunion.

Use this code for subsequent encounters when a patient presents with complications from a malunited, previously open lateral malleolus fracture. This applies to situations where the initial injury was an open fracture classified as Gustilo type I or II, and the current visit addresses the anatomical deformity or functional impairment caused by the malunion.

• Requires a seventh character of "Q" for subsequent encounter for malunion.
• Ensure documentation specifies an open fracture (type I or II) and malunion for accurate code assignment.
• Laterality (left or right fibula) is unspecified with this code; if known, a more specific code should be used.
