Unsp fracture of fifth metacarpal bone, left hand, init

This code signifies a fracture of the fifth metacarpal bone in the left 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 documenting a "boxer's fracture" or other fifth metacarpal fracture of the left hand when the physician's documentation does not specify the fracture type. It is used for the initial encounter when the fracture is closed and treatment is actively being rendered.

• Ensure the documentation explicitly states "left hand" and "fifth metacarpal" to support this specific code.
• Confirm the fracture is described as "closed" and that this is the patient's initial encounter for this injury.
• If the fracture type is later identified (e.g., comminuted, transverse), a more specific code should be used.
