Disp fx of nk of 2nd MC bone, l hand, 7thG

This code signifies a displaced fracture of the neck of the second metacarpal bone in the left hand. It specifically indicates that the patient is in a subsequent encounter for this fracture, and there is evidence of delayed healing. This suggests the fracture is not progressing to union at the expected rate.

Apply this code when a patient presents for follow-up care of a previously diagnosed displaced left second metacarpal neck fracture, and clinical or radiological findings confirm delayed healing. This would typically be used after initial treatment and during ongoing management to monitor healing progress.

• Ensure documentation clearly specifies "displaced" and "neck" for the second metacarpal.
• Verify the encounter is "subsequent" and explicitly mentions "delayed healing" to justify this specific seventh character.
• Confirm the laterality is "left hand" to avoid coding errors.
