Disp fx of navicular of left foot, subs for fx w delay heal

This code signifies a fracture of the navicular bone in the left foot that is no longer in its anatomical position. The patient is currently in a phase of treatment where the fracture is healing slower than expected, requiring ongoing medical attention.

Apply this code when documenting follow-up care for a patient with a displaced left foot navicular fracture who is experiencing delayed union. This includes scenarios such as cast changes, physical therapy, or medication management specifically addressing the slow healing process.

• Ensure documentation clearly states "displaced" and specifies the "left foot" navicular bone.
• Verify the encounter is for "subsequent care" and explicitly mentions "delayed healing."
• Do not use for initial fracture treatment or for fractures healing at a normal rate.
