Displ avuls fx tuberosity of unsp calcaneus, 7thP

This code describes a specific type of heel bone fracture where a piece of bone has been pulled away from the main calcaneus (avulsion) and is not in its proper anatomical position (displaced). This particular code is used when the patient is receiving ongoing care for a fracture that has healed incorrectly (malunion).

Apply this code for patients presenting for follow-up care, rehabilitation, or surgical intervention due to a previously sustained avulsion fracture of the calcaneal tuberosity that has healed with a deformity or misalignment. This indicates a complication of the initial fracture healing process.

• Requires a seventh character "P" for subsequent encounter for fracture with malunion.
• Ensure documentation clearly specifies "avulsion fracture of tuberosity" and "displaced" for the calcaneus.
• Distinguish from nonunion (S92.033N) or routine follow-up for a healing fracture (S92.033D).
