Displ avuls fx tuberosity of l calcaneus, 7thK

This code describes a specific type of heel bone fracture where a piece of the calcaneus tuberosity has been pulled away from the main bone (avulsion) and is not in its correct anatomical position (displaced). The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" signifies that the fracture has failed to heal completely after the expected healing period.

Use this code for patients presenting for ongoing treatment, evaluation, or management of a displaced avulsion fracture of the left calcaneal tuberosity that has not healed properly. This includes situations where surgical intervention for nonunion is being planned or performed, or conservative management for the nonunion is continuing.

• Ensure documentation clearly specifies "left" calcaneus and "tuberosity" to differentiate from other calcaneal fractures.
• Verify that the fracture is explicitly documented as "displaced" and that "nonunion" is confirmed by the physician.
• This code is for subsequent encounters only; an initial encounter for this fracture would use a different code.
