Disp fx of navicular of right foot, subs for fx w malunion

This diagnosis code signifies a previously treated fracture of the navicular bone in the right foot that has healed incorrectly, resulting in a deformity or functional impairment. The patient is currently receiving care for this complication, rather than the initial injury.

This code is appropriate for encounters where a patient is being managed for a malunion of a right foot navicular fracture. This includes follow-up appointments, evaluations for corrective surgery, or ongoing conservative management of the malunited fracture.

• Ensure documentation clearly states "malunion" and specifies the right foot navicular bone.
• Verify that this is a subsequent encounter for the fracture, not the initial treatment.
• Do not use this code for nonunion, which has a separate designation.
