Injury of left iliac vein, sequela

This code signifies a long-term complication or residual effect stemming from a past injury to the left iliac vein. It indicates that the initial acute injury has resolved, but its lasting impact, such as chronic venous insufficiency, post-thrombotic syndrome, or persistent pain, is still present and requires ongoing management.

Apply this code when documenting conditions that are direct consequences of a previous injury to the left iliac vein, even if the original injury occurred months or years ago. This is appropriate for follow-up encounters addressing chronic issues like venous stasis ulcers, edema, or pain directly attributable to the old vein trauma.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic venous insufficiency).
• Ensure documentation clearly links the current condition to a past left iliac vein injury.
• Do not use this code for the initial acute injury or for ongoing treatment of the acute phase.
