Oth fracture of left great toe, subs for fx w malunion

This code signifies a fracture of the left great toe (hallux) that is currently undergoing treatment, but the bone is healing in an abnormal or misaligned position. The malunion indicates that the bone fragments have united, but the alignment is not anatomically correct, potentially leading to functional impairment or deformity.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a previously diagnosed left great toe fracture that has healed or is healing with malunion. This includes scenarios where surgical intervention for correction of the malunion is being planned or has already occurred. It is appropriate for any encounter after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" and specifies the left great toe.
• Confirm this is not the initial encounter for the fracture; use the appropriate "initial encounter" code for the first visit.
• Always code any associated complications or sequelae of the malunion, such as pain or functional limitations, in addition to this code.
