Disp fx of shaft of 1st MC bone, l hand, 7thG

This code signifies a break in the long, central part of the first metacarpal bone (thumb) in the left hand, where the bone fragments are no longer in proper alignment. It specifically indicates that the patient is in a later stage of care for this fracture, and the healing process is taking longer than expected.

Apply this code when a patient presents for follow-up care of a previously diagnosed left first metacarpal shaft fracture that was displaced, and the physician documents delayed union or non-union. This would be used for subsequent visits after the initial treatment, where the fracture has not healed within the anticipated timeframe.

• Ensure documentation clearly specifies "left hand" and "shaft" of the first metacarpal.
• Verify that the fracture was initially documented as "displaced" and that "delayed healing" is explicitly stated or clearly implied by the clinical context.
• Do not use for initial encounter or for fractures that are healing normally.
