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

This code signifies a fracture of the great toe, excluding the phalanx or sesamoid, that has healed improperly, resulting in a malunion. The patient is presenting for follow-up care or treatment related to this previously sustained and now malunited fracture.

This code is appropriate for encounters where a patient is being evaluated or treated for complications arising from a malunited fracture of the great toe, such as pain, deformity, or functional limitations. It is used when the initial fracture has already healed in an unsatisfactory position.

• Ensure documentation clearly states "malunion" and specifies the great toe (hallux) as the affected digit.
• Verify that the encounter is for follow-up care related to the malunion, not the initial treatment of the acute fracture.
• Consider additional codes for any associated complications or sequelae of the malunion, such as chronic pain or osteoarthritis.
