Disp fx of mid 3rd of navic bone of l wrs, 7thK

This code describes a fracture located in the middle portion of the scaphoid bone in the left wrist that has failed to heal properly. The fracture fragments are not in their anatomical alignment, and the bone has not shown signs of union during the healing process. This indicates a persistent gap or fibrous tissue formation at the fracture site.

This code is appropriate for use when a patient presents for follow-up care of a previously diagnosed displaced scaphoid fracture of the left wrist, and clinical or radiological evidence confirms nonunion. This would typically be documented after a period of conservative or surgical management has failed to achieve bone healing. It is used for subsequent encounters, not the initial treatment.

• Ensure documentation clearly specifies "displaced" and "nonunion" for the left scaphoid's middle third.
• Verify this is a subsequent encounter for the fracture, not the initial injury or a routine follow-up without nonunion.
• Always sequence this code after any applicable external cause codes, if known and documented.
