Nondisp fx of navicular of left foot, subs for fx w malunion

This code signifies a left foot navicular (scaphoid) bone fracture that was initially nondisplaced but is now healing improperly, resulting in a malunion. The patient is in a subsequent phase of care, indicating ongoing management of the fracture.

Apply this code when documenting follow-up care for a patient whose left foot navicular fracture, initially nondisplaced, has healed in an anatomically incorrect position. This would be used for encounters where the malunion is being assessed, monitored, or treated.

• Ensure documentation clearly states "left foot" and "navicular [scaphoid]" to support laterality and specific bone.
• Verify the fracture was initially nondisplaced and that malunion is explicitly documented as the current healing status.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
