Oth fx unsp femur, subs for opn fx type 3A/B/C w delay heal

This code signifies a fracture of the femur that is not specifically categorized elsewhere, where the bone has broken through the skin (an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC). The "subsequent encounter" indicates the patient is receiving follow-up care for this injury, and "delayed healing" means the fracture is not mending at the expected rate.

Apply this code when documenting ongoing treatment for a complex open femoral fracture (types IIIA, IIIB, or IIIC) that is exhibiting delayed union. This would be used during clinic visits, hospital admissions, or other encounters where the primary focus is managing the slow healing process of such a fracture.

• Ensure documentation clearly specifies an "other" femoral fracture site and an open fracture type IIIA, IIIB, or IIIC.
• Confirm the encounter is for follow-up care, not the initial treatment, and that delayed healing is explicitly noted.
• Do not use for initial treatment of the fracture or for fractures that are healing normally.
