Injury of other iliac blood vessels, sequela

This code signifies a long-term or residual effect resulting from a past injury to any iliac blood vessel other than the main iliac artery or vein. These sequelae can include chronic pain, vascular insufficiency, or other persistent complications directly attributable to the original trauma.

Apply this code when documenting a current condition that is a direct consequence of a previous injury to a smaller iliac blood vessel (e.g., internal iliac artery/vein branches, external iliac artery/vein branches). This is appropriate for follow-up encounters where the acute injury has resolved, but its lasting impact is still being treated or evaluated.

• Always link this sequela code to an external cause code (V, W, X, Y category) if the original injury's cause is known.
• Ensure documentation clearly states the connection between the current condition and the past iliac blood vessel injury.
• Do not use for acute injuries; this code is specifically for residual effects.
