Laceration of posterior tibial artery, right leg, init

This diagnosis code signifies a tear or cut in the posterior tibial artery located in the right lower leg. This type of injury typically results in significant bleeding and potential compromise of blood flow to the foot and ankle.

This code is appropriate for documenting an initial presentation of a patient with a confirmed laceration of the right posterior tibial artery, often due to trauma such as a penetrating injury or severe blunt force. It should be used for the first encounter where the injury is diagnosed and treated.

• Ensure documentation clearly specifies the right leg and the posterior tibial artery.
• Confirm this is the initial encounter for this specific injury; subsequent encounters would use a different seventh character.
• Always code any associated external cause of injury (e.g., W25.xxxA for contact with sharp glass) and place of occurrence codes.
