Oth fracture of first metacarpal bone, unsp hand, init

This code signifies a fracture of the first metacarpal bone (thumb) that is not specifically a Bennett's or Rolando's fracture. It indicates that the skin over the fracture site is intact (closed fracture) and that this is the initial treatment encounter for the injury. The specific hand affected is not documented.

This code is appropriate for documenting a newly diagnosed, non-displaced or minimally displaced fracture of the thumb's metacarpal bone when the physician does not specify the fracture type as Bennett's or Rolando's. It applies when the patient is presenting for their first visit related to this particular injury.

• Ensure documentation explicitly states "other" or an unspecified type of first metacarpal fracture.
• Confirm the encounter is for initial treatment; subsequent encounters will require a different 7th character.
• Verify the fracture is closed; open fractures have distinct codes.
