Disp fx of shaft of 1st MC bone, l hand, 7thK

This code signifies a left-sided fracture of the shaft of the first metacarpal bone (thumb) that is displaced and has failed to heal properly. The "subsequent encounter" indicates that the patient is being seen for ongoing management of this previously diagnosed fracture, specifically due to nonunion.

This code is appropriate for follow-up visits where a patient is being treated for a non-healing, displaced fracture of the left first metacarpal shaft. This includes scenarios such as evaluation for surgical intervention to address the nonunion, or ongoing conservative management of the nonunion.

• Ensure documentation clearly specifies "left hand" and "first metacarpal shaft."
• Verify the fracture is explicitly documented as "displaced" and that "nonunion" is present.
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
