Major lacerat right innominate or subclav vein, sequela

This code signifies a significant, long-term complication or residual effect stemming from a previous major injury to the right innominate (brachiocephalic) or subclavian vein. This could involve persistent issues such as chronic venous insufficiency, thrombosis, or other structural damage that continues to impact the patient's health after the initial acute injury has resolved.

Apply this code when documenting the sequelae of a major laceration to the right innominate or subclavian vein, indicating that the initial injury occurred in the past and the patient is now experiencing a chronic or residual condition directly attributable to it. This is appropriate for follow-up encounters where the long-term consequences of the original trauma are being managed.

• Always use this code in conjunction with an external cause code to fully describe the circumstances of the original injury.
• Ensure documentation clearly links the current condition as a direct result of the past major laceration to the specified vein.
• Do not use this code for the initial acute injury; it is specifically for the long-term effects or complications.
