Unspecified injury of inferior vena cava, sequela

This code signifies a long-term or late-effect complication resulting from an unspecified injury to the inferior vena cava (IVC). It indicates that the initial acute injury has resolved, but the patient is now experiencing ongoing health problems directly attributable to that past trauma.

Apply this code when documentation clearly links a current condition or symptom to a previous, unspecified injury of the IVC, and the acute phase of the injury has passed. This is appropriate for conditions like chronic venous insufficiency, post-thrombotic syndrome, or other persistent sequelae stemming from an old IVC injury.

• Always ensure the "S" (sequela) seventh character is appended when coding for late effects.
• Code the specific current condition or symptom first, followed by this sequela code to provide a complete clinical picture.
• Verify that the medical record explicitly states the current condition is a direct consequence of a past IVC injury.
