Oth fracture of unsp metacarpal bone, init for clos fx

This code signifies a fracture of a metacarpal bone in the hand, excluding the thumb (first metacarpal), where the specific metacarpal involved is not documented. It indicates that the skin over the fracture is intact (closed fracture) and this is the initial treatment for the injury.

Apply this code when documentation confirms a closed fracture of a metacarpal bone (second through fifth), but the specific metacarpal (e.g., second, third, fourth, or fifth) is not clearly identified. This is appropriate for the initial encounter for treatment of the fracture.

• Ensure the documentation specifies a closed fracture and an initial encounter.
• Only use this code if the specific metacarpal (2nd-5th) is truly unspecified; otherwise, use a more specific code.
• Do not use for fractures of the first metacarpal (thumb), as those have dedicated codes.
