Fracture of unsp carpal bone, left wrist, init for clos fx

This code signifies a break in any of the eight carpal bones of the left wrist, where the specific bone involved is not documented. It indicates that the skin over the fracture site remains intact, and this is the initial treatment for the injury.

Apply this code when a patient presents with a newly diagnosed, closed fracture of a carpal bone in the left wrist, but imaging or clinical documentation does not specify which carpal bone is affected. This is appropriate for the initial encounter for treatment of such a fracture.

• Ensure documentation explicitly states "left wrist" and "closed fracture."
• Only use this code if a more specific carpal bone fracture (e.g., scaphoid, lunate) cannot be identified.
• The "A" seventh character indicates an initial encounter for active treatment of the fracture.
