Unsp injury of anterior tibial artery, right leg, init

This code signifies an injury to the anterior tibial artery in the right leg where the specific type of injury (e.g., laceration, puncture, contusion) is not documented. It indicates that the patient is receiving initial active treatment for this vascular trauma.

Use this code for a patient presenting with an acute injury to the right anterior tibial artery, such as from a fall, direct blow, or penetrating trauma, when the physician's documentation does not specify the exact nature of the arterial damage. This code is appropriate when the patient is first seen for this condition and is undergoing diagnostic workup or initial surgical repair.

• Ensure the documentation clearly states "right leg" and "anterior tibial artery."
• Only use the "A" seventh character for the initial encounter for active treatment of the injury.
• If the specific type of injury (e.g., laceration, transection) is documented, a more specific code from the S85.1- series should be used.
