Unsp fracture of first metacarpal bone, right hand, init

This code signifies a fracture of the first metacarpal bone (thumb) in the right hand, where the specific type of fracture (e.g., transverse, oblique) is not documented. The skin overlying the fracture remains intact, indicating a closed injury. This code is used for the initial treatment phase of the injury.

This code is appropriate for a patient presenting with a newly diagnosed, non-displaced or minimally displaced fracture of the right thumb metacarpal, where the physician's documentation does not specify the fracture pattern. It is used for the initial encounter when the patient is receiving active treatment for the fracture.

• Ensure documentation explicitly states "unspecified" or lacks detail regarding the fracture type for the first metacarpal.
• Verify the fracture is on the right hand and is a closed injury.
• Confirm this is the initial encounter for active treatment; subsequent encounters will require a different seventh character.
