Disp fx of trapezium, left wrist, subs for fx w delay heal

This code signifies a fracture of the trapezium bone in the left wrist, where the bone fragments are no longer in their normal alignment. The fracture is not healing at the expected rate, indicating a complication in the recovery process. This diagnosis is made during a follow-up visit after initial treatment.

Use this code for a patient presenting for a follow-up appointment for a previously diagnosed left trapezium fracture that was displaced and is now exhibiting delayed healing. This applies when the patient is still receiving active treatment for the fracture, such as cast changes, physical therapy, or surgical planning for nonunion.

• Ensure documentation clearly specifies "left wrist" and "displaced" for the trapezium fracture.
• Verify that the encounter is for "delayed healing" and not routine follow-up or initial treatment.
• Confirm the seventh character "G" for subsequent encounter with delayed healing is appropriate.
