Disp fx of posterior process of unsp talus, init for opn fx

This code describes a break in the posterior process of the talus bone, which is located in the ankle. The fracture is displaced, meaning the bone fragments are not in their normal anatomical alignment. This specific code indicates an open fracture, where the skin and soft tissue are compromised, exposing the bone.

Use this code for the initial treatment of a patient presenting with a displaced open fracture of the posterior process of the talus. This typically occurs following high-impact trauma or significant ankle injury where the bone has broken through the skin. It is appropriate for the first encounter where definitive treatment, such as surgical intervention or initial wound care, is provided.

• Ensure documentation clearly specifies "displaced" and "open fracture" of the posterior process of the talus.
• Verify this is the "initial encounter" for treatment of the open fracture; subsequent encounters will use different seventh characters.
• Laterality (left/right) is unspecified in this code; if known, a more specific code should be chosen.
