Disp fx of body of hamate bone, l wrs, 7thK

This code signifies a fracture of the main part of the hamate bone in the left wrist that has shifted out of its normal anatomical position. Importantly, the bone fragments have failed to heal together after a previous attempt, indicating a nonunion.

This code is appropriate for encounters where a patient is receiving ongoing treatment for a previously diagnosed displaced left hamate body fracture that has not united. This includes follow-up visits, cast changes, or preparations for surgical intervention to address the nonunion. It would not be used for the initial injury or for a fracture that is healing normally.

• Ensure documentation clearly specifies "left wrist" and "body of hamate" to support this specific code.
• The "K" seventh character indicates a subsequent encounter for a fracture with nonunion; verify the encounter type aligns with this.
• Distinguish this from malunion (improper healing) or routine healing, which use different seventh characters.
