Unsp fx third MC bone, left hand, subs for fx w delay heal

This code signifies a fracture of the third metacarpal bone in the left hand where the specific type of fracture (e.g., transverse, oblique) is not documented. The encounter is for follow-up care of this fracture, and the healing process is progressing slower than expected.

This code is appropriate for subsequent encounters when a patient presents with a previously diagnosed, unspecified fracture of the left third metacarpal, and the physician notes delayed healing. This would include situations where the patient is undergoing continued treatment, such as cast changes, physical therapy, or monitoring, due to the slow healing.

• Ensure documentation clearly states "delayed healing" for the fracture.
• Verify the laterality (left hand) and the specific bone (third metacarpal).
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
