Unsp injury of right innominate or subclavian vein, sequela

This code signifies a long-term complication or late effect resulting from an unspecified injury to the right innominate (brachiocephalic) or subclavian vein. It indicates that the initial acute injury has resolved, but residual issues related to that trauma persist. The specific nature of the original injury and the current sequela are not detailed.

Use this code when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a past, unspecified injury of the right innominate or subclavian vein. This is appropriate for follow-up encounters where the primary focus is managing the chronic effects of such an injury, rather than the acute phase. Examples include chronic pain, venous insufficiency, or scarring affecting the vessel.

• Always sequence this code after the code describing the specific sequela (e.g., chronic venous insufficiency).
• Ensure documentation clearly links the current condition to a past injury of the specified vein.
• If the laterality is unknown or the injury affects both sides, a more general code should be considered.
