Disp fx of trapezoid, unsp wrist, subs for fx w delay heal

This code signifies a fracture of the trapezoid bone in the wrist that is no longer in its anatomical alignment, affecting an unspecified wrist. The patient is currently in a phase of treatment where the fracture is not healing at the expected rate.

This code is appropriate for follow-up encounters for a patient with a previously diagnosed displaced trapezoid fracture who is experiencing delayed union. It should be used when the specific wrist (left or right) is not documented.

• Requires a seventh character to indicate the encounter type and healing status.
• Ensure documentation clearly states "delayed healing" for this specific seventh character.
• Do not use if the fracture is in malunion or nonunion; different seventh characters apply.
