Nondisp fx of lateral cuneiform of l ft, 7thK

This code describes a situation where a patient has a fracture of the lateral cuneiform bone in their left foot that was initially nondisplaced, but has failed to heal properly. The patient is currently receiving care for this ununited fracture.

Use this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced lateral cuneiform fracture of the left foot that has progressed to a nonunion. This applies to encounters where treatment for the nonunion, such as surgical intervention or cast changes, is being provided.

• Ensure documentation clearly specifies "nonunion" for the subsequent encounter.
• Verify the fracture is of the lateral cuneiform and on the left foot.
• Confirm the initial fracture was nondisplaced; displaced fractures would use a different code.
