Nondisp fx of trapezium, unsp wrist, init for clos fx

This code signifies a break in the trapezium bone of the wrist that has not shifted out of its normal anatomical alignment. The injury is to an unspecified wrist, meaning the documentation does not specify whether it's the left or right wrist.

This code is appropriate for the initial visit for a patient presenting with a newly diagnosed, non-displaced fracture of the trapezium bone. It is used when the medical record does not specify the laterality of the injury (left or right wrist) and the skin over the fracture is intact.

• Ensure documentation explicitly states "nondisplaced" and "closed fracture."
• Only use this code for the initial encounter for treatment of the fracture.
• If laterality (left or right wrist) is specified, a more specific code should be used.
