Nondisp fx of prox 3rd of navic bone of unsp wrs, 7thK

This code signifies a fracture of the navicular (scaphoid) bone in the wrist, specifically in its proximal third, that is not displaced. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone is failing to heal properly.

Use this code for patients presenting for ongoing treatment of a previously diagnosed, nondisplaced proximal navicular fracture where the bone has not united. This would include clinic visits for cast changes, follow-up imaging to assess healing progress (or lack thereof), or discussions regarding further intervention for the nonunion.

• Ensure documentation clearly states "nondisplaced" and specifies the "proximal third" of the navicular bone.
• Verify the encounter is for follow-up care and not the initial treatment.
• Confirm the physician's assessment explicitly indicates "nonunion" of the fracture.
