Oth injury of right innominate or subclavian vein, sequela

This code signifies a long-term complication or residual effect stemming from a previously sustained injury to the right innominate (brachiocephalic) or subclavian vein. This could include conditions like chronic venous insufficiency, post-thrombotic syndrome, or persistent pain directly attributable to the original trauma.

Apply this code when documenting a patient presenting for treatment of a current condition that is a direct consequence of an old injury to the right innominate or subclavian vein. This is appropriate for follow-up encounters where the acute injury has resolved, but its lasting impact is being addressed.

• Ensure documentation clearly links the current condition to the previous right innominate/subclavian vein injury.
• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic venous insufficiency).
• Verify that the "S" seventh character for sequela is appropriate, indicating the long-term nature of the condition.
