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

This code indicates a fracture at the base of the third metacarpal bone in the left hand that has healed improperly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not in their normal alignment. This code is used when the patient is receiving follow-up care for this previously treated, but now malunited, fracture.

Use this code for patients presenting for treatment or management of a malunited fracture of the base of the left third metacarpal. This applies to situations such as surgical correction of the malunion, physical therapy to address functional deficits from the malunion, or ongoing pain management related to the improper healing. It signifies that the initial fracture treatment has concluded, and the current encounter addresses the complication of malunion.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the laterality (left hand) and the specific bone (third metacarpal base).
• This "P" seventh character indicates a subsequent encounter for a fracture with malunion, not the initial treatment or routine follow-up for a healing fracture.
