Unsp injury of unsp tibial artery, unsp leg, init encntr

This code signifies an injury to a tibial artery in the leg, where the specific artery (anterior or posterior tibial) and the exact leg affected are not documented. It indicates the initial phase of treatment for such an injury, without specifying the nature of the trauma (e.g., laceration, contusion).

Use this code when a patient presents with an acute injury to a tibial artery, but the medical record lacks detail regarding which specific tibial artery is involved or which leg is affected. This is appropriate for the initial visit or encounter for this particular injury.

• Only use this code when documentation is truly ambiguous regarding the specific tibial artery and laterality.
• Always strive for greater specificity if available in the medical record (e.g., S85.11- for anterior tibial artery, S85.12- for posterior tibial artery).
• Ensure the "A" seventh character is appropriate for the initial encounter for this injury.
