Nondisp avuls fx tuberosity of unsp calcaneus, 7thK

This code describes a specific type of foot fracture where a small piece of bone is pulled away from the tuberosity of the calcaneus (heel bone) by a tendon or ligament, but the bone fragments remain in their normal alignment. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" signifies that the fracture has failed to heal properly.

Use this code for patients presenting for ongoing treatment of a previously diagnosed, nondisplaced avulsion fracture of the calcaneal tuberosity that has not united. This would include scenarios such as continued immobilization, physical therapy, or surgical planning for nonunion management.

• Ensure documentation clearly states "nondisplaced avulsion fracture" and "nonunion."
• Verify this is a subsequent encounter for the fracture, not the initial treatment.
• Confirm the fracture location is the tuberosity of the calcaneus; other calcaneal fracture types have different codes.
