Major laceration of left external jugular vein, sequela

This code signifies a long-term complication or residual effect stemming from a significant tear or wound to the external jugular vein on the left side of the neck. It indicates that the initial injury has healed, but a lasting issue, such as chronic pain, scarring, nerve damage, or impaired circulation, persists as a direct result.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a previously sustained major laceration to the left external jugular vein. Documentation should clearly link the current sequela to the historical injury, often through physician notes detailing the patient's history and current symptoms.

• Always use an additional code to specify the nature of the sequela (e.g., chronic pain, scar formation, nerve palsy).
• Ensure the medical record explicitly states that the current condition is a "sequela" or "late effect" of the original injury.
• Distinguish from acute injuries; this code is for residual conditions after the initial healing phase.
