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

This code signifies a break in the trapezium bone of the left wrist that has not shifted out of its normal anatomical position. The fracture is contained within the skin, meaning there is no open wound communicating with the bone.

Apply this code for the initial treatment of a patient presenting with a newly diagnosed, non-displaced fracture of the left trapezium. This typically occurs following a fall onto an outstretched hand or direct trauma to the thumb side of the wrist.

• Confirm the fracture is specifically of the trapezium and not another carpal bone.
• Verify the documentation explicitly states "nondisplaced" and "left wrist."
• Ensure this is the patient's first encounter for this specific fracture; subsequent care will require a different encounter character.
