Displaced unsp fx left great toe, subs for fx w malunion

This code signifies a fracture of the left great toe (hallux) that has healed in an abnormal position, leading to a deformity (malunion). The initial fracture was displaced, meaning the bone fragments were out of alignment, and the specific type of fracture is not documented. This code is used when the patient is receiving follow-up care for this malunited fracture.

Use this code for patients presenting for treatment of complications arising from a malunited fracture of the left great toe, such as pain, functional impairment, or cosmetic concerns. This applies to subsequent encounters where the malunion itself is the focus of the visit, rather than the initial healing phase. Examples include evaluation for corrective surgery or ongoing management of symptoms related to the deformity.

• Ensure documentation clearly states "malunion" and specifies the left great toe.
• Verify that the encounter is for follow-up care of the malunion, not initial fracture treatment.
• Do not use this code if the fracture is still in the healing phase (nonunion) or if the malunion is not displaced.
