Unsp fracture of third metacarpal bone, left hand, init

This code signifies a fracture of the third metacarpal bone in the left hand, where the specific type of fracture (e.g., transverse, oblique, spiral) is not documented. It indicates that the skin over the fracture site remains intact, and this is the initial encounter for treatment.

This code is appropriate when a patient presents with a newly diagnosed, closed fracture of the left third metacarpal, and the provider's documentation does not specify the fracture type. It is used for the initial phase of treatment, such as emergency room visits or initial orthopedic consultations.

• Ensure documentation explicitly states "left hand" and "third metacarpal."
• Only use for closed fractures; open fractures require different codes.
• The "A" suffix indicates initial encounter; subsequent care will require different suffixes.
