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

This code signifies a fracture of the navicular bone in the right foot that has shifted out of its normal alignment and is not healing properly. The "subsequent encounter" indicates that the patient is receiving ongoing care for this previously diagnosed injury, and "nonunion" confirms that the bone fragments have failed to unite after a reasonable healing period.

Use this code for follow-up visits where a patient with a displaced right navicular fracture is being treated for a confirmed nonunion. This applies to scenarios such as evaluation for surgical intervention to promote healing, management of pain related to the nonunion, or monitoring the progression of the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right foot and navicular bone.
• Verify that the fracture was initially displaced, as this is a specific characteristic of the code.
• Do not use for initial treatment or for fractures that are healing normally (malunion or routine healing).
