Unspecified injury of portal vein, sequela

This code signifies a long-term complication or late effect stemming from an unspecified injury to the portal vein. It indicates that the initial acute injury has resolved, but the patient is now experiencing residual problems directly attributable to that past trauma.

Use this code when documenting a patient presenting with a current condition that is a direct consequence of a previous, unspecified portal vein injury. This applies when the original injury is no longer acute and the sequela is the primary reason for the current encounter.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a prior portal vein injury.
• Avoid using this code for acute or initial portal vein injuries; those require acute injury codes.
