Displaced avulsion fx tuberosity of l calcaneus, init

This diagnosis code signifies a specific type of foot fracture involving the left calcaneus (heel bone). It describes a displaced avulsion fracture, meaning a fragment of bone has been pulled away from the tuberosity (a bony prominence) due to a ligament or tendon injury, and the fragment is not in its anatomical position. This code is used for the initial treatment phase of this closed fracture, indicating the skin remains intact over the injury site.

This code is appropriate for the initial encounter when a patient presents with a newly diagnosed displaced avulsion fracture of the tuberosity of their left calcaneus. It applies to situations where the fracture is managed non-surgically or during the initial workup for surgical repair. Subsequent encounters for fracture care would require different seventh characters.

• Confirm the laterality (left) and the specific bone (calcaneus) and location (tuberosity) are accurately documented.
• Verify the fracture type is explicitly stated as "displaced avulsion fracture."
• Ensure the encounter is indeed the "initial encounter" for this specific fracture to use the 'A' seventh character.
