Unsp injury of unspecified internal jugular vein, sequela

This code signifies a long-term complication or late effect stemming from an unspecified injury to an internal jugular vein, where the specific nature of the original injury and the affected side are not documented. It indicates that the initial acute injury has resolved, but its lasting consequences are now being addressed.

Use this code when a patient presents with a current condition or symptom that is a direct result of a past, unspecified injury to an internal jugular vein, and the specific side (left or right) is not specified. Documentation should clearly link the current sequela to a previous internal jugular vein injury.

• Always assign a sequela code (ending in 'S') as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure the medical record explicitly states that the current condition is a "late effect" or "sequela" of a prior internal jugular vein injury.
• Avoid using this code if the acute injury is still being treated; instead, use an acute injury code from the S15.30 category.
