Disp fx of base of third metacarpal bone, left hand, init

This code signifies a break in the base of the third metacarpal bone in the left hand, where the bone fragments are not properly aligned. It indicates that this is the initial treatment encounter for a fracture that has not broken through the skin.

Apply this code for patients presenting with a newly diagnosed, non-aligned fracture at the base of their left third metacarpal. This is appropriate for the initial visit where definitive treatment, such as reduction and casting, is planned or initiated for a closed fracture.

• Ensure documentation specifies "displaced" and "base of third metacarpal" for the left hand.
• Confirm the encounter is for the initial treatment of a closed fracture (e.g., no open wound).
• Do not use for subsequent encounters or for open fractures; different codes apply.
