Oth fx low end unsp femr, 7thQ

This code describes a situation where a patient is receiving follow-up care for a previously sustained open fracture of the lower end of an unspecified femur, which has now healed incorrectly (malunion). The original open fracture was classified as Type I or II, indicating a relatively clean wound with minimal soft tissue damage.

This code is appropriate for subsequent encounters when a patient presents with complications of a malunited open fracture of the distal femur, originally classified as Type I or II. This would include scenarios such as surgical correction of the malunion, physical therapy for functional deficits due to the malunion, or ongoing pain management related to the improperly healed fracture.

• Ensure documentation clearly specifies "malunion" as the complication of the fracture.
• Verify the original fracture was an "open fracture type I or II" and that this is a "subsequent encounter."
• Do not use this code for nonunion, delayed union, or initial treatment of the fracture.
