Disp fx of base of 3rd MC bone, l hand, 7thK

This code signifies a left-sided fracture at the base of the third metacarpal bone that is no longer in its anatomical alignment. The patient is in a later phase of treatment where the bone fragments have failed to heal together properly, indicating a nonunion.

Apply this code when documenting follow-up care for a patient with a previously diagnosed displaced fracture of the left third metacarpal base, and the physician explicitly notes that the fracture has not united. This is appropriate for encounters involving ongoing management, surgical intervention for nonunion, or evaluation of delayed healing.

• Ensure documentation clearly specifies "left hand" and "third metacarpal base" to support this precise code.
• The "K" seventh character indicates a subsequent encounter for a nonunion, so verify the physician's assessment of healing status.
• Do not use this code for initial treatment or for fractures that are healing normally.
