Complication of vein following a procedure, NEC, sequela

This code signifies a long-term or late-effect complication affecting a vein that arose from a previous medical or surgical procedure. These complications are not classified more specifically elsewhere in ICD-10-CM and manifest after the initial healing period of the original procedure. It indicates that the venous issue is a direct consequence of a past intervention.

Use this code when documenting a chronic or residual venous complication that is clearly linked to a prior procedure, such as post-procedural venous insufficiency, chronic phlebitis, or persistent venous obstruction not due to an acute event. This code is appropriate when the initial complication has resolved, but its lasting effects on the vein are still present and require ongoing management.

• Requires a seventh character "S" to indicate sequela, meaning the complication is a late effect of the original procedure.
• Always sequence this code after the code(s) identifying the specific nature of the venous complication (e.g., chronic venous insufficiency).
• Ensure documentation clearly establishes the causal link between the prior procedure and the current venous complication.
