Disp fx of lunate, unsp wrist, subs for fx w malunion

This code signifies a fracture of the lunate bone in an unspecified wrist that has healed incorrectly, resulting in a malunion. The fracture was displaced, meaning the bone fragments were not in their normal alignment. This code is used for follow-up care after the initial treatment of the fracture.

Apply this code when a patient presents for ongoing management of a previously treated lunate fracture that has demonstrably healed in an unsatisfactory alignment. This includes scenarios where the malunion is causing persistent pain, functional limitations, or requiring further intervention. It is appropriate for any encounter after the initial treatment phase where malunion is the focus.

• Ensure documentation clearly states "malunion" and specifies the lunate bone.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the wrist laterality is unspecified in the clinical notes to align with the code's specificity.
