Major laceration of unsp external jugular vein, sequela

This code signifies a long-term complication or late effect resulting from a significant tear or cut in an external jugular vein, where the specific side (left or right) of the injury was not documented. It indicates that the initial acute injury has resolved, but its lasting consequences are now being addressed.

Apply this code when a patient presents with a condition directly attributable to a previously sustained, major laceration of an external jugular vein, and the initial injury occurred in the past. Documentation should clearly link the current sequela to the prior jugular vein trauma and specify the lack of laterality in the original injury report.

• Always use a "sequela" code (ending in "S") as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation explicitly states the laceration was "major" and that the laterality was "unspecified" at the time of the original injury.
• Distinguish from acute injuries (codes without "S" suffix) and superficial lacerations.
