Displaced dome fx left talus, subs for fx w delay heal

This code signifies a fracture of the dome (superior articular surface) of the talus bone in the left foot, where the bone fragments are no longer in their anatomical alignment. The patient is in a subsequent phase of care, and the fracture is not healing at the expected rate.

Apply this code when documenting follow-up care for a patient with a previously diagnosed displaced dome fracture of the left talus who is experiencing delayed union. This would be used after the initial treatment phase, such as casting or surgery, but before the fracture has fully consolidated.

• Ensure documentation clearly specifies "left" talus and "displaced" fracture.
• Confirm that the encounter is for ongoing management of the fracture, not the initial treatment or a sequela.
• Look for physician notes indicating "delayed healing," "delayed union," or similar terminology.
