Unsp injury of unspecified tibial artery, right leg, sequela

This code indicates a long-term complication or late effect resulting from an injury to an unspecified tibial artery in the right leg. The original injury itself is not specified, and the current diagnosis reflects a residual condition or sequela.

This code is appropriate when documenting a current condition that is a direct consequence of a past injury to a right tibial artery, and the specific nature of the original injury or the affected artery branch is not known or documented. It is used when the patient is presenting for treatment of the sequela, not the acute injury.

• Always sequence this code after the code for the specific sequela (e.g., chronic pain, nonunion, scar formation).
• Only use this code when the specific tibial artery (anterior, posterior, or peroneal) is not documented.
• The "S" at the end indicates a sequela, meaning it's for conditions arising as a late effect of an injury.
