Unspecified injury of popliteal vein, left leg, sequela

This code indicates a long-term or late effect resulting from an unspecified injury to the popliteal vein in the left leg. It signifies that the initial injury has healed, but residual symptoms, complications, or conditions persist due to that past trauma. The specific nature of the original injury is not documented or is unknown.

Use this code when a patient presents with a current condition directly attributable to a previous, unspecified injury of the left popliteal vein. This applies to situations where the acute phase of the original injury has passed, and the current encounter addresses a chronic sequela, such as chronic venous insufficiency, post-thrombotic syndrome, or persistent pain stemming from the old injury.

• Always use an additional code to identify the specific sequela or residual condition being treated.
• This "S" seventh character indicates a sequela, meaning the patient is seen for a complication or condition resulting from a previous injury.
• Do not use this code for acute injuries; instead, use the appropriate acute injury code for the initial encounter.
