Laceration of portal vein, sequela

📋Clinical Description

This code signifies a long-term complication or residual effect stemming from a laceration of the portal vein. These sequelae can manifest months or even years after the initial injury and may include conditions such as portal hypertension, strictures, or chronic thrombosis. It indicates that the patient is experiencing ongoing health issues directly attributable to the past portal vein trauma.

🎯When to Use

Apply this code when documenting a patient's current condition that is a direct consequence of a previously sustained laceration of the portal vein. This is appropriate for follow-up encounters where the initial acute injury has resolved, but its lasting impact is still being treated or monitored. Use it when the patient's current symptoms or diagnoses are directly linked to the historical portal vein damage.

💡Coding Tips

Always use in conjunction with an external cause code (V00-Y99) to specify the circumstances of the original injury, if known.
Requires a seventh character "S" to indicate sequela, signifying a late effect.
Do not use for the initial acute injury; this code is exclusively for residual conditions.
