Disp fx of ant process of unsp calcaneus, init for opn fx

This code signifies a break in the front part of the heel bone (calcaneus) that is out of its normal alignment. It specifically indicates that the skin and soft tissue overlying the fracture are also broken, exposing the bone to the outside environment. This is an initial encounter for treatment of this specific injury.

Apply this code for a patient presenting with a newly diagnosed open fracture of the anterior process of the calcaneus, where the laterality (left or right) of the foot is not documented. This is appropriate for the initial surgical repair, debridement, or other definitive treatment of the open fracture.

• Ensure documentation clearly states "open fracture" and "anterior process of calcaneus."
• Only use this code for the initial treatment phase; subsequent encounters will require different seventh characters.
• Confirm that laterality is truly unspecified; if left or right is documented, a more specific code should be used.
