Disp fx of neck of unsp MC bone, subs for fx w delay heal

This code signifies a fracture of the metacarpal neck, where the bone fragments are no longer in their normal alignment. It specifically indicates that the patient is in a later stage of healing, but the fracture is not progressing as expected. This typically involves persistent pain, swelling, or radiographic evidence of incomplete union beyond the anticipated healing timeframe.

Use this code for follow-up encounters when a patient with a previously diagnosed displaced metacarpal neck fracture is experiencing delayed healing. This applies when the fracture site shows signs of incomplete consolidation or non-union after the initial treatment phase. It would be appropriate for patients presenting for re-evaluation, casting changes, or consideration of further intervention due to slow healing.

• Ensure documentation clearly specifies "displaced" and "delayed healing" for the metacarpal neck fracture.
• Verify that the encounter is a subsequent visit for the fracture, not the initial treatment.
• Confirm the specific metacarpal bone is not identified in the documentation, necessitating the "unspecified" laterality.
