Nondisp avuls fx tuberosity of l calcaneus, 7thK

This code signifies a specific type of heel bone fracture where a small piece of bone has been pulled away from the main bone by a tendon or ligament, but the bone fragments remain in their normal anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone has failed to heal properly after a typical healing period.

Apply this code when documenting ongoing treatment for a patient with a previously diagnosed avulsion fracture of the left calcaneal tuberosity that has not united. This includes scenarios where the patient is undergoing further evaluation, conservative management, or surgical intervention to address the nonunion. It is appropriate for follow-up visits after the initial diagnosis and treatment.

• Ensure documentation clearly states "left calcaneus," "avulsion fracture," "nondisplaced," and "nonunion" for accurate code assignment.
• This code is for subsequent encounters only; an initial encounter for this fracture would use a different seventh character.
• Verify laterality (left) is explicitly documented to avoid coding errors.
