Disp fx of base of metacarpal bone, subs for fx w delay heal

This code signifies a fracture at the base of a metacarpal bone (excluding the thumb) that is no longer in its anatomical alignment. It indicates that the patient is presenting for follow-up care, and the fracture is not healing at the expected rate.

Apply this code when a patient with a previously diagnosed displaced fracture of the base of a metacarpal (other than the first) is seen for ongoing management due to delayed union. This would typically be used in subsequent visits after the initial treatment, where the fracture has not yet fully consolidated.

• Ensure documentation clearly specifies "displaced" and "delayed healing" for a metacarpal base fracture.
• Confirm the fracture is not of the thumb metacarpal (first metacarpal).
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
