Oth fx left femur, subs for opn fx type I/2 w delay heal

This code signifies a fracture of the left femur, excluding those of the shaft, neck, or trochanteric regions, that was initially an open fracture (Type I or II) and is now being treated during a subsequent encounter due to delayed healing. It indicates that the bone is not mending at the expected rate for this specific type of injury.

Use this code when a patient presents for follow-up care of a previously diagnosed open fracture (Type I or II) of the left femur (excluding shaft, neck, or trochanteric) and the physician documents that the healing process is prolonged or not progressing as anticipated. This applies to situations where the initial injury has been treated, but the fracture site is still unstable or showing signs of non-union/malunion in its early stages.

• Ensure documentation clearly specifies "delayed healing" for the left femur fracture.
• Verify the original fracture was an open fracture, Type I or II, as indicated by the 7th character.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
